Organization, Consolidation and Presentation of Financial Statements [Abstract]
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS Recently Adopted Accounting Pronouncements: In June 2016, the FASB issued ASU 2016-13, "Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." The new guidance within ASU 2016-13, along with related updates (collectively "ASC 326") introduces an approach based on expected losses to estimate credit losses on certain types of financial instruments. The new guidance became effective for annual periods beginning after December 15, 2019, and interim periods within those annual periods. Accordingly, the Company adopted ASC 326 on January 1, 2020, using the modified retrospective transition method through a $2.2 million cumulative-effect decrease to retained earnings (see Note 11). The Company has also made updates to its policies and internal controls over financial reporting as a result of adoption. In August 2018, the FASB issued ASU 2018-15, "Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." The new guidance aligns the requirements for capitalizing implementation costs incurred in a cloud-based hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). ASU 2018-15 became effective for annual periods beginning after December 15, 2019, and interim periods within those annual periods. Accordingly, the Company adopted ASU 2018-15 on January 1, 2020, using the prospective method of adoption, and the adoption did not have a material impact to the Condensed and Consolidated Financial Statements. Recently Issued Accounting Pronouncements In December 2019, the FASB issued ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes." The new guidance is intended to simplify the accounting for income taxes by removing certain exceptions and by updating accounting requirements around franchise taxes, goodwill recognized for tax purposes, the allocation of current and deferred tax expense among legal entities, among other minor changes. The ASU is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. Early adoption is permitted. The Company is assessing what impact ASU 2019-12 will have on the Condensed and Consolidated Financial Statements. In January 2020, the FASB issued ASU 2020-01, "Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815): Clarifying the Interactions between Topic 321, Topic 323, and Topic 815." The amendments in ASU 2020-01 clarify the interaction of the accounting for equity securities under Topic 321 and investments accounted for under the equity method of accounting. The ASU is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. Early adoption is permitted. The Company is assessing what impact ASU 2020-01 will have on the Condensed and Consolidated Financial Statements. In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." This ASU provides temporary optional expedients and exceptions for applying GAAP to contract modifications, hedging relationships and other transactions if certain criteria are met in order to ease the potential accounting and financial reporting burden associated with the expected market transition away from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. The ASU is currently effective and may be applied prospectively at any point through December 31, 2022 at the Company’s option. The Company is assessing what impact ASU 2020-04 will have on the Condensed and Consolidated Financial Statements.

As quoted market prices are not available for these reporting units, the calculations of their estimated fair values were based on a discounted cash flow model (income approach). This was a change in estimate, as historically the Company’s determination of reporting unit fair values has been estimated based on two valuation techniques, a discounted cash flow model (income approach) and a market multiple of earnings (market approach), with each method being weighted in the calculation. Given the high degree of market volatility and lack of reliable market data that existed as of March 31, 2020, the Company determined that a discounted cash flow model (income approach) provided the best approximation of fair value of the EMEA and Asia Pacific reporting units for the purpose of performing these interim impairment tests.

The Credit Facilities mature on September 12, 2022, and are unconditionally guaranteed jointly and severally on an unsecured basis by the Company and Allegion US Holding Company Inc. ("Allegion US Hold Co"), the Company’s wholly-owned subsidiary. At inception, the Term Facility was scheduled to amortize in quarterly installments at the following rates: 1.25% per quarter starting December 31, 2017 through December 31, 2020, 2.5% per quarter from March 31, 2021 through June 30, 2022, with the balance due on September 12, 2022. Principal amounts repaid on the Term Facility may not be reborrowed. During the third quarter of 2019, the Company made a $400.0 million principal payment to partially pay down the outstanding Term Facility balance. As a result of this payment, the Company has satisfied its obligation to make quarterly installments on the Term Facility up to the maturity date, with the remaining outstanding balance due on September 12, 2022. The Revolving Facility provides aggregate commitments of up to $500.0 million, which includes up to $100.0 million for the issuance of letters of credit. At June 30, 2020, there were no borrowings outstanding on the Revolving Facility and the Company had $16.3 million of letters of credit outstanding. Commitments under the Revolving Facility may be reduced at any time without premium or penalty, and amounts repaid may be reborrowed. Outstanding borrowings under the Credit Facilities accrue interest, at the option of the Company, of (i) a LIBOR rate plus the applicable margin or (ii) a base rate plus the applicable margin. The applicable margin ranges from 1.125% to 1.500% depending on the Company’s credit ratings. At June 30, 2020, the outstanding borrowings under the Credit Facilities accrue interest at LIBOR plus a margin of 1.250%. To manage the Company’s exposure to fluctuations in LIBOR rates, the Company has interest rate swaps to fix the interest rate for $200.0 million of the outstanding borrowings, which expire in September 2020 (see Note 7). The weighted-average interest rate for borrowings was 2.41% under the Credit Facilities (including the effect of interest rate swaps) at June 30, 2020. The Credit Facilities contain negative and affirmative covenants and events of default that, among other things, limit or restrict the Company’s ability to enter into certain transactions. In addition, the Credit Facilities require the Company to comply with a maximum leverage ratio and a minimum interest expense coverage ratio, as defined within the agreement. As of June 30, 2020, the Company was in compliance with all covenants. Senior Notes

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments	FINANCIAL INSTRUMENTS In the normal course of business, the Company uses various financial instruments, including derivative instruments, to manage the risks associated with interest and currency rate exposures. These financial instruments are not used for trading or speculative purposes. When a derivative contract is entered into, the Company designates the derivative instrument as a cash flow hedge of a forecasted transaction, a cash flow hedge of a recognized asset or liability or as an undesignated derivative. The Company formally documents its hedge relationships, including identification of the derivative instruments and the hedged items, as well as its risk management objectives and strategies for undertaking the hedge transaction. This process includes linking derivative instruments that are designated as hedges to specific assets, liabilities or forecasted transactions. The fair market value of derivative instruments is determined through market-based valuations and may not be representative of the actual gains or losses that will be recorded when these instruments mature due to future fluctuations in the markets in which they are traded. The Company assesses at inception and at least quarterly thereafter, whether the derivatives used in cash flow hedging transactions are effective in offsetting the changes in the cash flows of the hedged item. To the extent the derivative is deemed to be an effective hedge, the fair market value changes of the instrument are recorded to Accumulated other comprehensive income (AOCI) and subsequently reclassified into Net earnings when the hedged transaction affects earnings. Changes in the fair market value of derivatives not deemed to be an effective hedge are recorded in Net earnings in the period of change. If the hedging relationship ceases to be effective subsequent to inception, or it becomes probable that a forecasted transaction is no longer expected to occur, the hedging relationship will be undesignated and any future gains and losses on the derivative instrument will be recorded in Net earnings. Currency Hedging Instruments The gross notional amount of the Company’s currency derivatives was $155.0 million and $146.4 million at June 30, 2020 and December 31, 2019, respectively. At June 30, 2020 and December 31, 2019, a gain of $0.6 million and a loss of $0.1 million, net of tax, respectively, were included in Accumulated other comprehensive loss related to the fair value of the Company’s currency derivatives designated as cash flow hedges. The amount expected to be reclassified into Net earnings over the next twelve months is a gain of $0.6 million. The actual amounts that will be reclassified to Net earnings may vary from this amount as a result of changes in market conditions. Gains and losses associated with the Company’s currency derivatives not designated as hedges are recorded in Net earnings as changes in fair value occur. At June 30, 2020, the maximum term of the Company’s currency derivatives was less than one year. Interest Rate Swaps The Company has interest rate swaps to fix the interest rate paid during the contract period related to $200.0 million of the Company’s variable rate Term Facility. These interest rate swaps expire in September 2020 and meet the criteria to be accounted for as cash flow hedges of variable rate interest payments. Consequently, the changes in fair value of the interest rate swaps are recognized in Accumulated other comprehensive loss. At June 30, 2020 and December 31, 2019, a loss of $0.4 million and a gain of $0.5 million, net of tax, respectively, were included in Accumulated other comprehensive loss related to these interest rate swaps. The amount expected to be reclassified into Net earnings over the next twelve months is a loss of approximately $0.4 million. The fair values of derivative instruments included within the Condensed and Consolidated Balance Sheets were as follows: Designated as hedge instruments Not designated as hedge instruments In millions Balance Sheet classification June 30, December 31, June 30, December 31, Asset derivatives Currency derivatives Other current assets $ 0.6 $ — $ 0.6 $ 0.4 Interest rate swaps Other current assets — 0.7 — — Total asset derivatives $ 0.6 $ 0.7 $ 0.6 $ 0.4 Liability derivatives Currency derivatives Accrued expenses and other current liabilities $ 0.5 $ 0.8 $ 1.0 $ 0.7 Interest rate swaps Accrued expenses and other current liabilities 0.5 — — — Total liability derivatives $ 1.0 $ 0.8 $ 1.0 $ 0.7 The amounts associated with derivatives designated as hedges affecting Net earnings and Accumulated other comprehensive loss for the three months ended June 30 were as follows: Amount of gain (loss) recognized in Accumulated other comprehensive loss Location of gain recognized Amount of gain reclassified from Accumulated other comprehensive loss and In millions 2020 2019 2020 2019 Currency derivatives $ — $ 0.4 Cost of goods sold $ 2.1 $ 1.3 Interest rate swaps — (1.5) Interest expense 0.1 0.8 Total $ — $ (1.1) $ 2.2 $ 2.1 The amounts associated with derivatives designated as hedges affecting Net earnings and Accumulated other comprehensive loss for the six months ended June 30 were as follows: Amount of gain (loss) recognized in Accumulated other comprehensive loss Location of gain recognized Amount of gain reclassified from Accumulated other comprehensive loss and In millions 2020 2019 2020 2019 Currency derivatives $ 3.0 $ 1.0 Cost of goods sold $ 2.1 $ 3.3 Interest rate swaps (0.8) (2.2) Interest expense 0.4 1.7 Total $ 2.2 $ (1.2) $ 2.5 $ 5.0 The gains and losses associated with the Company’s non-designated currency derivatives, which are offset by changes in the fair value of the underlying transactions, are included within Other (income) expense, net in the Condensed and Consolidated Statements of Comprehensive Income. Concentration of Credit Risk The counterparties to the Company’s forward contracts and swaps consist of a number of investment grade major international financial institutions. The Company could be exposed to losses in the event of nonperformance by the counterparties. However, the credit ratings and the concentration of risk in these financial institutions are monitored on a continuous basis and present no significant credit risk to the Company.

Leases [Abstract]
Leases	LEASES The Company records a right-of-use ("ROU") asset and lease liability for substantially all leases for which it is a lessee, in accordance with ASC 842. At inception of a contract, the Company considers all relevant facts and circumstances to assess whether or not the contract represents a lease by determining whether or not the contract conveys a right to control the use of an identified asset, either explicit or implicit, for a period of time in exchange for consideration. The Company has no significant lease agreements in place for which the Company is a lessor, and substantially all of the Company’s leases for which the Company is a lessee are classified as operating leases. Total rental expense for the six months ended June 30, 2020 and 2019, was $21.6 million and $21.6 million, respectively, and is classified within Cost of goods sold and Selling and administrative expenses within the Condensed and Consolidated Statements of Comprehensive Income. Rental expense related to short-term leases, variable lease payments or other leases or lease components not included within the ROU asset or lease liability totaled $4.7 million and $4.9 million, respectively, for the six months ended June 30, 2020 and 2019. No material lease costs have been capitalized on the Condensed and Consolidated Balance Sheets as of June 30, 2020 or December 31, 2019. If at the lease commencement date, a lease has a term of less than 12 months and does not include a purchase option that is reasonably certain to be exercised, the Company does not include the lease as part of its ROU asset or lease liability. If the Company enters into a large number of leases in the same month with the same terms and conditions, these are considered a group (portfolio), assuming the lease model under this approach does not materially differ from applying ASC 842 to each individual lease. When available, the Company will utilize the rate implicit in the lease as the discount rate to determine the lease liability. However, as this rate is not available for most leases, the Company will use its incremental borrowing rate as the discount rate, which is the rate at inception of the lease the Company would hypothetically incur to borrow over a similar term the funds needed to purchase the leased asset. As a lessee, the Company categorizes its leases into two general categories: real estate leases and equipment leases. The Company’s real estate leases include leased production and assembly facilities, warehouses and distribution centers, office space and to a lesser degree, employee housing. The terms and conditions of real estate leases can vary significantly from lease to lease. The Company has assessed the specific terms and conditions of each real estate lease to determine the amount of the lease payments and the length of the lease term, which includes the minimum period over which lease payments are required plus any renewal options that are both within the Company’s control to exercise and reasonably certain of being exercised upon lease commencement. The Company assesses all relevant factors to determine if sufficient incentives exist as of lease commencement to conclude whether or not renewal is reasonably certain. There are no material residual value guarantees provided by the Company nor any restrictions or covenants imposed by the real estate leases to which the Company is a party. In determining the lease liability, the Company utilizes its incremental borrowing rate for debt instruments with terms approximating the weighted-average term for its real estate leases to discount the future lease payments over the lease term to present value. The Company does incur variable lease payments for certain of its real estate leases, such as reimbursements of property taxes, maintenance and other operational costs to the lessor. In general, these variable lease payments are not captured as part of the lease liability or ROU asset, but rather are expensed as incurred. The Company’s equipment leases include vehicles, material handling equipment, other machinery and equipment utilized in the Company’s production and assembly facilities, warehouses and distribution centers, laptops and other IT equipment, and other miscellaneous leased equipment. Most of the equipment leases are for terms ranging from two to five years, although terms and conditions can vary from lease to lease. The Company applies similar estimates and judgments to its equipment lease portfolio in determining the lease payments and lease term as it does to its real estate lease portfolio. There are no material residual value guarantees provided by the Company nor any restrictions or covenants imposed by the equipment leases to which the Company is a party. In determining the lease liability, the Company utilizes its incremental borrowing rate for debt instruments with terms approximating the weighted-average term for its equipment leases to discount the future lease payments over the lease term to present value. The Company does not typically incur variable lease payments related to its equipment leases. Amounts included within the Condensed and Consolidated Balance Sheet related to the Company’s ROU asset and lease liability were as follows: June 30, 2020 December 31, 2019 In millions Balance Sheet classification Real estate Equipment Total Real estate Equipment Total ROU asset Other noncurrent assets $ 50.0 $ 23.1 $ 73.1 $ 57.5 $ 23.9 $ 81.4 Lease liability - current Accrued expenses and other current liabilities 14.2 10.5 24.7 15.4 10.4 25.8 Lease liability - noncurrent Other noncurrent liabilities 36.3 12.6 48.9 42.1 13.5 55.6 Other information: Weighted-average remaining term (years) 6.6 2.6 6.5 2.8 Weighted-average discount rate 4.4 % 3.6 % 4.5 % 3.8 % The following table summarizes additional information related to the Company’s leases for the six months ended June 30: 2020 2019 In millions Real estate Equipment Total Real estate Equipment Total Cash paid for amounts included in the measurement of lease liabilities $ 9.7 $ 7.2 $ 16.9 $ 9.6 $ 7.1 $ 16.7 ROU assets obtained in exchange for new lease liabilities 1.5 6.8 8.3 7.0 6.2 13.2 The Company frequently enters into both real estate and equipment leases in the normal course of business. While there have been lease agreements entered into that have not yet commenced as of June 30, 2020, none of these leases provide new rights or obligations to the Company that are material individually or in the aggregate. Future Repayments Scheduled minimum lease payments required under non-cancellable operating leases for both the real estate and equipment lease portfolios for the remainder of 2020 and for each of the years thereafter as of June 30, 2020, are as follows: In millions Remainder of 2020 2021 2022 2023 2024 Thereafter Total Real estate leases $ 8.5 $ 14.5 $ 10.5 $ 6.3 $ 3.7 $ 15.5 $ 59.0 Equipment leases 6.0 9.3 5.7 2.2 0.9 0.1 24.2 Total $ 14.5 $ 23.8 $ 16.2 $ 8.5 $ 4.6 $ 15.6 $ 83.2 The difference between the total undiscounted minimum lease payments and the combined current and noncurrent lease liabilities as of June 30, 2020, is due to imputed interest of $9.6 million.

Retirement Benefits, Description [Abstract]
Pensions and Postretirement Benefits Other than Pensions	PENSIONS AND POSTRETIREMENT BENEFITS OTHER THAN PENSIONS The Company sponsors several U.S. defined benefit and defined contribution plans covering substantially all of its U.S. employees. Additionally, the Company has non-U.S. defined benefit and defined contribution plans covering eligible non-U.S. employees. Postretirement benefits, other than pensions, provide healthcare benefits, and in some instances, life insurance benefits, for certain eligible employees. Pension Plans The noncontributory defined benefit pension plans covering non-collectively bargained U.S. employees provide benefits on an average pay formula while most plans for collectively bargained U.S. employees provide benefits on a flat dollar benefit formula. The non-U.S. pension plans generally provide benefits based on earnings and years of service. The Company also maintains additional other supplemental plans for officers and other key employees. The components of the Company’s Net periodic pension benefit cost (income) for the three and six months ended June 30 were as follows: U.S. Three months ended Six months ended In millions 2020 2019 2020 2019 Service cost $ 1.9 $ 1.5 $ 3.8 $ 3.0 Interest cost 2.5 2.8 4.9 5.7 Expected return on plan assets (3.6) (3.1) (7.3) (6.3) Administrative costs and other 0.4 0.4 0.9 0.8 Net amortization of: Prior service costs — 0.1 0.1 0.2 Plan net actuarial losses 1.0 1.1 2.0 2.1 Net periodic pension benefit cost $ 2.2 $ 2.8 $ 4.4 $ 5.5 Non-U.S. Three months ended Six months ended In millions 2020 2019 2020 2019 Service cost $ 0.5 $ 0.4 $ 1.0 $ 0.8 Interest cost 1.7 2.2 3.4 4.4 Expected return on plan assets (3.2) (3.3) (6.5) (6.5) Administrative costs and other 0.3 0.4 0.7 0.7 Net amortization of: Prior service costs — — — 0.1 Plan net actuarial losses 0.3 0.4 0.7 0.7 Net curtailment and settlement losses — 1.4 — 1.4 Net periodic pension benefit (income) cost $ (0.4) $ 1.5 $ (0.7) $ 1.6 The Service cost component of Net periodic pension benefit cost (income) is recorded in Cost of goods sold and Selling and administrative expenses within the Condensed and Consolidated Statements of Comprehensive Income. The remaining components of Net periodic pension benefit cost (income) are recorded within Other (income) expense, net within the Condensed and Consolidated Statements of Comprehensive Income. Employer contributions were not material during the six months ended June 30, 2020 and 2019. Contributions of approximately $10 million are expected during the remainder of 2020. Postretirement Benefits Other Than Pensions The Company sponsors a postretirement ("OPEB") plan that provides for healthcare benefits, and in some instances, life insurance benefits, that cover certain eligible retired employees. The Company funds postretirement benefit obligations principally on a pay-as-you-go basis. Generally, postretirement health benefits are contributory with contributions adjusted annually. Life insurance plans for retirees are primarily noncontributory. Net periodic postretirement benefit cost (income) is included within Other (income) expense, net within the Condensed and Consolidated Statements of Comprehensive Income.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS Fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Fair value measurements are based on a framework that utilizes the inputs market participants use to determine the fair value of an asset or liability and establishes a fair value hierarchy to prioritize those inputs. The fair value hierarchy is comprised of three levels that are described below: • Level 1 – Inputs based on quoted prices in active markets for identical assets or liabilities. • Level 2 – Inputs other than Level 1 quoted prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability. • Level 3 – Unobservable inputs based on little or no market activity and that are significant to the fair value of the assets and liabilities. The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Observable inputs are obtained from independent sources and can be validated by a third party, whereas unobservable inputs reflect assumptions regarding what a third party would use in pricing an asset or liability based on the best information available under the circumstances. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Assets and liabilities measured at fair value at June 30, 2020, were as follows: Fair value measurements Total In millions Quoted prices in active markets for identical assets (Level 1) Significant other observable inputs (Level 2) Significant unobservable inputs (Level 3) Recurring fair value measurements Assets: Investments $ — $ 20.0 $ — $ 20.0 Derivative instruments — 1.2 — 1.2 Total asset recurring fair value measurements $ — $ 21.2 $ — $ 21.2 Liabilities: Derivative instruments $ — $ 2.0 $ — $ 2.0 Deferred compensation and other retirement plans — 21.7 — 21.7 Total liability recurring fair value measurements $ — $ 23.7 $ — $ 23.7 Financial instruments not carried at fair value Total debt $ — $ 1,504.0 $ — $ 1,504.0 Total financial instruments not carried at fair value $ — $ 1,504.0 $ — $ 1,504.0 Assets and liabilities measured at fair value at December 31, 2019, were as follows: Fair value measurements Total In millions Quoted prices in active markets for identical assets (Level 1) Significant other observable inputs (Level 2) Significant unobservable inputs (Level 3) Recurring fair value measurements Assets: Investments $ — $ 17.4 $ — $ 17.4 Derivative instruments — 1.1 — 1.1 Total asset recurring fair value measurements $ — $ 18.5 $ — $ 18.5 Liabilities: Derivative instruments $ — $ 1.5 $ — $ 1.5 Deferred compensation and other retirement plans — 23.1 — 23.1 Total liability recurring fair value measurements $ — $ 24.6 $ — $ 24.6 Financial instruments not carried at fair value Total debt $ — $ 1,474.0 $ — $ 1,474.0 Total financial instruments not carried at fair value $ — $ 1,474.0 $ — $ 1,474.0 The Company determines the fair value of its financial assets and liabilities using the following methodologies: • Investments – These instruments include equity mutual funds and corporate bond funds. The fair value is obtained based on observable market prices quoted on public exchanges for similar instruments. • Derivative instruments – These instruments include foreign currency contracts for non-functional currency balance sheet exposures, including both those that are designated as cash flow hedges and those that are not, as well as interest rate swap contracts related to the Company’s variable rate Term Facility. The fair value of the foreign currency contracts is determined based on a pricing model that uses spot rates and forward prices from actively quoted currency markets that are readily accessible and observable. The fair value of the interest rate swap contracts is determined based on quoted prices for the Company’s swaps, which is not considered an active market. • Deferred compensation and other retirement plans – These include obligations related to deferred compensation and other retirement plans adjusted for market performance. The fair value is obtained based on observable market prices quoted on public exchanges for similar instruments. • Debt – These instruments are recorded at cost and include senior notes maturing through 2029. The fair value of the long-term debt instruments is obtained based on observable market prices quoted on public exchanges for similar instruments. The carrying values of Cash and cash equivalents, Restricted cash, Accounts and notes receivable, Accounts payable and Accrued expenses and other current liabilities are a reasonable estimate of their fair value due to the short-term nature of these instruments. The Company had investments in debt and equity securities without readily determinable fair values of $21.4 million and $18.1 million as of June 30, 2020 and December 31, 2019, respectively, which are classified as Other noncurrent assets within the Condensed and Consolidated Balance Sheets. These investments are measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments of the same issuer and are qualitatively assessed for impairment indicators at each reporting period. These investments are considered to be nonrecurring fair value measurements, and thus, are not included in the fair value tables above. The methodologies used by the Company to determine the fair value of its financial assets and liabilities at June 30, 2020, are the same as those used at December 31, 2019.

Share-based Payment Arrangement, Noncash Expense [Abstract]
Share-Based Compensation	SHARE-BASED COMPENSATION The Company records share-based compensation awards using a fair value method and recognizes compensation expense for an amount equal to the fair value of the share-based payment issued in its financial statements. The Company’s share-based compensation plans include programs for stock options, restricted stock units ("RSUs"), performance stock units ("PSUs") and deferred compensation. Compensation Expense Share-based compensation expense is included in Cost of goods sold and Selling and administrative expenses within the Condensed and Consolidated Statements of Comprehensive Income. The following table summarizes the expenses recognized for the three and six months ended June 30: Three months ended Six months ended In millions 2020 2019 2020 2019 Stock options $ 0.4 $ 0.4 $ 3.0 $ 2.8 RSUs 2.2 2.0 7.6 6.4 PSUs (1.0) 1.8 0.4 3.4 Deferred compensation 2.2 0.5 0.2 2.2 Pre-tax expense 3.8 4.7 11.2 14.8 Tax benefit (a) (1.0) (0.6) (1.4) (1.8) After-tax expense $ 2.8 $ 4.1 $ 9.8 $ 13.0 (a) Tax benefit reflected in the table above does not include the excess benefit from exercises and vesting of share based compensation of $0.3 million during the three months ended June 30, 2019, and $4.0 million and $1.2 million during the six months ended June 30, 2020 and 2019, respectively. Stock Options / RSUs Eligible participants may receive (i) stock options, (ii) RSUs or (iii) a combination of both stock options and RSUs. Grants issued during the six months ended June 30 were as follows: 2020 2019 Number Weighted- Number Weighted- Stock options 161,600 $ 25.62 195,675 $ 19.58 RSUs 77,570 $ 126.19 115,137 $ 89.21 The fair value of each of the Company’s stock option and RSU awards is expensed on a straight-line basis over the required service period, which is generally the three-year vesting period. However, for stock options and RSUs granted to retirement eligible employees, the Company recognizes expense for the fair value at the grant date. The average fair value of the stock options granted is determined using the Black-Scholes option-pricing model. The following assumptions were used during the six months ended June 30: 2020 2019 Dividend yield 0.99 % 1.23 % Volatility 20.70 % 21.44 % Risk-free rate of return 1.41 % 2.53 % Expected life (years) 6.0 6.0 Expected volatility is based on the Company’s historic volatility for the prior six years. The risk-free rate of return is based on the yield curve of a zero-coupon U.S. Treasury bond on the date the award is granted with a maturity equal to the expected term of the award. The expected life of the Company’s stock option awards is derived from the simplified approach based on the weighted-average time to vest and the remaining contractual term and represents the period of time that awards are expected to be outstanding. Performance Stock The Company has a Performance Stock Program ("PSP") for key employees which provides awards in the form of PSUs based on performance against pre-established objectives. The annual target award level is expressed as a number of the Company’s ordinary shares. All PSUs are settled in the form of ordinary shares unless deferred. During the six months ended June 30, 2020, the Company granted PSUs with a maximum award level of approximately 0.1 million shares. In February 2018, 2019 and 2020, the Company’s Compensation Committee granted PSUs that were earned based 50% upon a performance condition, measured at each reporting period by earnings per share ("EPS") performance in relation to pre-established targets set by the Compensation Committee, and 50% upon a market condition, measured by the Company’s relative total shareholder return ("TSR") against the S&P 400 Capital Goods Index over a three-year performance period. The fair values of the market conditions are estimated using a Monte Carlo Simulation approach in a risk-neutral framework to model future stock price movements based upon historical volatility, risk-free rates of return and correlation matrix. Deferred Compensation Prior to 2019, the Company allowed key employees to defer a portion of their eligible granted PSUs and/or compensation into a number of investment choices including its ordinary share equivalents. Any amounts invested in ordinary share equivalents will be settled in ordinary shares of the Company at the time of distribution.

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The effective income tax rates for the three months ended June 30, 2020 and 2019, were 16.2% and 16.9%, respectiv ely. The decrease in the effective tax rate compared to 2019 is primarily due to the favorable mix of income earned in lower tax rate jurisdictions. The effective income tax rates for the six months ended June 30, 2020 and 2019, were 25.7% and 16.4%, respectively. The increase in the effective tax rate compared to 2019 is primarily due to the unfavorable tax impact related to the goodwill and indefinite-lived trade name impairment charges, partially offset by the favorable benefit of excess share-based compensation deductions and the favorable mix of income earned in lower tax rate jurisdictions.

Earnings Per Share [Abstract]
Earnings Per Share (EPS)	EARNINGS PER SHARE (EPS) Basic EPS is calculated by dividing Net earnings attributable to Allegion plc by the weighted-average number of ordinary shares outstanding for the applicable period. Diluted EPS is calculated after adjusting the denominator of the basic EPS calculation for the effect of all potentially dilutive ordinary shares, which in the Company’s case, includes shares issuable under share-based compensation plans. The following table summarizes the weighted-average number of ordinary shares outstanding for basic and diluted EPS calculations for the three and six months ended June 30: Three months ended Six months ended In millions 2020 2019 2020 2019 Weighted-average number of basic shares 92.3 93.8 92.5 94.1 Shares issuable under incentive stock plans 0.4 0.7 0.5 0.7 Weighted-average number of diluted shares 92.7 94.5 93.0 94.8 At June 30, 2020, 0.1 million stock options were excluded from the computation of weighted-average diluted shares outstanding because the effect of including these shares would have been anti-dilutive.

Net Revenues

Net Revenues	6 Months Ended

Revenue from Contract with Customer [Abstract]
Net Revenues	NET REVENUES Net revenues are recognized based on the satisfaction of performance obligations under the terms of a contract. A performance obligation is a promise in a contract to transfer control of a distinct product or to provide a service, or a bundle of products or services, to a customer, and is the unit of account under ASC Topic 606, "Revenue from Contracts with Customers" (ASC 606). The Company has two principal revenue streams, tangible product sales and services. Approximately 99% of consolidated Net revenues involve contracts with a single performance obligation, which is the transfer of control of a product or bundle of products to a customer. Transfer of control typically occurs when goods are shipped from the Company’s facilities or at other predetermined control transfer points (for instance, destination terms). Net revenues are measured as the amount of consideration expected to be received in exchange for transferring control of the products and takes into account variable consideration, such as sales incentive programs including discounts and volume rebates. The existence of these programs does not preclude revenue recognition but does require the Company’s best estimate of the variable consideration to be made based on expected activity, as these items are reserved for as a deduction to Net revenues over time based on the Company’s historical rates of providing these incentives and annual forecasted sales volumes. The Company also offers a standard warranty with most product sales, and the value of such warranty is included in the contractual price. The corresponding expense of the warranty obligation is accrued as a liability (see Note 19). The Company’s remaining Net revenues involve services, including installation and consulting. Unlike the single performance obligation to ship a product or bundle of products, revenue recognition related to services is delayed until the service performance obligations are satisfied. In some instances, customer acceptance provisions are included in sales arrangements to give the buyer the ability to ensure the service meets the criteria established in the order. In these instances, revenue recognition is deferred until the performance obligations are satisfied, which could include acceptance terms specified in the arrangement being fulfilled through customer acceptance or a demonstration that established criteria have been satisfied. During the six months ended June 30, 2020 and 2019, no adjustments were recorded related to performance obligations satisfied in previous periods. The Company applies the practical expedients allowed under ASC 606 to omit the disclosure of remaining performance obligations for contracts with an original expected duration of one year or less and for contracts where the Company has the right to invoice for performance completed to date. The transaction price is not adjusted for the effects of a significant financing component, as the time period between control transfer of goods and services is less than one year. Sales, value-added and other similar taxes collected by the Company are excluded from Net revenues. The Company has also elected to account for shipping and handling activities that occur after control of the related goods transfers as fulfillment activities instead of performance obligations. These activities are included in Cost of goods sold in the Condensed and Consolidated Statements of Comprehensive Income. The Company’s payment terms are generally consistent with the industries in which its businesses operate. The following tables show the Company’s Net revenues related to both tangible product sales and services for the three and six months ended June 30, 2020 and 2019, respectively, disaggregated by business segment. Net revenues are shown by tangible product sales and services, as contract terms, conditions and economic factors affecting the nature, amount, timing and uncertainty around revenue recognition and cash flows are substantially similar within each of these two principal revenue streams: Three months ended June 30, 2020 Six months ended June 30, 2020 In millions Americas EMEA Asia Pacific Total Americas EMEA Asia Pacific Consolidated Net revenues Products $ 444.3 $ 106.0 $ 32.6 $ 582.9 $ 956.4 $ 231.6 $ 63.5 $ 1,251.5 Services — 5.0 1.6 6.6 — 9.3 3.4 12.7 Total Net revenues $ 444.3 $ 111.0 $ 34.2 $ 589.5 $ 956.4 $ 240.9 $ 66.9 $ 1,264.2 Three months ended June 30, 2019 Six months ended June 30, 2019 In millions Americas EMEA Asia Pacific Total Americas EMEA Asia Pacific Consolidated Net revenues Products $ 545.1 $ 137.1 $ 41.8 $ 724.0 $ 1,020.4 $ 275.8 $ 76.5 $ 1,372.7 Services — 5.1 2.1 7.2 — 9.3 4.2 13.5 Total Net revenues $ 545.1 $ 142.2 $ 43.9 $ 731.2 $ 1,020.4 $ 285.1 $ 80.7 $ 1,386.2 As of June 30, 2020, neither the contract assets related to the Company’s right to consideration for work completed but not billed, nor the contract liabilities associated with contract revenue were material. As a practical expedient, the Company recognizes incremental costs of obtaining a contract, if any, as an expense when incurred if the amortization period of the asset would have been one year or less. The Company does not have any costs to obtain or fulfill a contract that are capitalized.

Segment Reporting [Abstract]
Business Segment Information	BUSINESS SEGMENT INFORMATION The Company classifies its business into the following three reportable segments based on industry and market focus: Americas, Europe, Middle East and Africa ("EMEA") and Asia Pacific. Results for the Company's India operations are now included within the Asia Pacific segment results, due to an operational change during the three months ended June 30, 2020. This change did not result, and is not expected to result, in a material impact to Segment results of operations for either the EMEA or Asia Pacific segment. The Company largely evaluates performance based on Segment operating income (loss) and Segment operating margins. Segment operating income (loss) is the measure of profit and loss that the Company’s chief operating decision maker uses to evaluate the financial performance of the business and as the basis for resource allocation, performance reviews and compensation. For these reasons, the Company believes that Segment operating income (loss) represents the most relevant measure of segment profit and loss. The Company’s chief operating decision maker may exclude certain charges or gains, such as corporate charges and other special charges, from Operating income (loss) to arrive at a Segment operating income (loss) that is a more meaningful measure of profit and loss upon which to base operating decisions. The Company defines Segment operating margin as Segment operating income (loss) as a percentage of the segment’s Net revenues. A summary of operations by reportable segment for the three and six months ended June 30 was as follows: Three months ended Six months ended In millions 2020 2019 2020 2019 Net revenues Americas $ 444.3 $ 545.1 $ 956.4 $ 1,020.4 EMEA 111.0 142.2 240.9 285.1 Asia Pacific 34.2 43.9 66.9 80.7 Total $ 589.5 $ 731.2 $ 1,264.2 $ 1,386.2 Segment operating income (loss) Americas $ 120.8 $ 161.2 $ 267.4 $ 282.1 EMEA (5.6) 1.6 (4.5) 12.4 Asia Pacific (3.6) 1.3 (101.5) (0.2) Total 111.6 164.1 161.4 294.3 Reconciliation to Operating income Unallocated corporate expense (15.1) (18.4) (36.0) (40.6) Operating income 96.5 145.7 125.4 253.7 Reconciliation to earnings before income taxes Interest expense 13.0 13.4 25.9 27.1 Other (income) expense, net (4.4) 0.7 (0.4) (0.4) Earnings before income taxes $ 87.9 $ 131.6 $ 99.9 $ 227.0

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES The Company is involved in various litigation, claims and administrative proceedings, including those related to environmental and product warranty matters. Amounts recorded for identified contingent liabilities are estimates, which are reviewed periodically and adjusted to reflect additional information when it becomes available. Subject to the uncertainties inherent in estimating future costs for contingent liabilities, except as expressly set forth in this note, management believes that any liability which may result from these legal matters would not have a material adverse effect on the financial condition, results of operations, liquidity or cash flows of the Company. Environmental Matters The Company is dedicated to an environmental program to reduce the utilization and generation of hazardous materials during the manufacturing process and to remediate identified environmental concerns. As to the latter, the Company is currently engaged in site investigations and remediation activities to address environmental cleanup from past operations at current and former production facilities. The Company regularly evaluates its remediation programs and considers alternative remediation methods that are in addition to, or in replacement of, those currently utilized by the Company based upon enhanced technology and regulatory changes. Changes to the Company’s remediation programs may result in increased expenses and increased environmental reserves. The Company is sometimes a party to environmental lawsuits and claims and has received notices of potential violations of environmental laws and regulations from the U.S. Environmental Protection Agency and similar state authorities. It has also been identified as a potentially responsible party ("PRP") for cleanup costs associated with off-site waste disposal at federal Superfund and state remediation sites. For all such sites, there are other PRPs and, in most instances, the Company’s involvement is minimal. In estimating its liability, the Company has assumed it will not bear the entire cost of remediation of any site to the exclusion of other PRPs who may be jointly and severally liable. The ability of other PRPs to participate has been taken into account, based on our understanding of the parties’ financial condition and probable contributions on a per site basis. Additional lawsuits and claims involving environmental matters are likely to arise from time to time in the future. During the three months ended June 30, 2020 and 2019, the Company incurred $0.3 million and $0.6 million, respectively, of expenses for environmental remediation at sites presently or formerly owned or leased by the Company. During the six months ended June 30, 2020 and 2019, the Company incurred $0.8 million and $1.0 million, respectively, of expenses for environmental remediation at sites presently or formerly owned or leased by the Company. As of June 30, 2020 and December 31, 2019, the Company has recorded reserves for environmental matters of $18.3 million and $19.3 million, respectively. The total reserve at June 30, 2020 and December 31, 2019, included $3.9 million and $4.2 million, respectively, related to remediation of sites previously disposed by the Company. Environmental reserves are classified as Accrued expenses and other current liabilities or Other noncurrent liabilities within the Condensed and Consolidated Balance Sheets based on their expected term. The Company’s total current environmental reserve at June 30, 2020 and December 31, 2019, was $ 5.4 million and $6.2 million, respectively, and the remainder is classified as noncurrent. Given the evolving nature of environmental laws, regulations and technology, the ultimate cost of future compliance is uncertain. Warranty Liability Standard product warranty accruals are recorded at the time of sale and are estimated based upon product warranty terms and historical experience. The Company assesses the adequacy of its liabilities and will make adjustments as necessary based on known or anticipated warranty claims, or as new information becomes available. The changes in the standard product warranty liability for the six months ended June 30 were as follows: In millions 2020 2019 Balance at beginning of period $ 15.9 $ 14.5 Reductions for payments (3.3) (4.4) Accruals for warranties issued during the current period 3.9 5.7 Changes to accruals related to preexisting warranties (0.2) (0.2) Currency translation (0.1) — Balance at end of period $ 16.2 $ 15.6 Standard product warranty liabilities are classified as Accrued expenses and other current liabilities within the Condensed and Consolidated Balance Sheets.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS Recently Adopted Accounting Pronouncements: In June 2016, the FASB issued ASU 2016-13, "Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." The new guidance within ASU 2016-13, along with related updates (collectively "ASC 326") introduces an approach based on expected losses to estimate credit losses on certain types of financial instruments. The new guidance became effective for annual periods beginning after December 15, 2019, and interim periods within those annual periods. Accordingly, the Company adopted ASC 326 on January 1, 2020, using the modified retrospective transition method through a $2.2 million cumulative-effect decrease to retained earnings (see Note 11). The Company has also made updates to its policies and internal controls over financial reporting as a result of adoption. In August 2018, the FASB issued ASU 2018-15, "Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." The new guidance aligns the requirements for capitalizing implementation costs incurred in a cloud-based hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). ASU 2018-15 became effective for annual periods beginning after December 15, 2019, and interim periods within those annual periods. Accordingly, the Company adopted ASU 2018-15 on January 1, 2020, using the prospective method of adoption, and the adoption did not have a material impact to the Condensed and Consolidated Financial Statements. Recently Issued Accounting Pronouncements In December 2019, the FASB issued ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes." The new guidance is intended to simplify the accounting for income taxes by removing certain exceptions and by updating accounting requirements around franchise taxes, goodwill recognized for tax purposes, the allocation of current and deferred tax expense among legal entities, among other minor changes. The ASU is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. Early adoption is permitted. The Company is assessing what impact ASU 2019-12 will have on the Condensed and Consolidated Financial Statements. In January 2020, the FASB issued ASU 2020-01, "Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815): Clarifying the Interactions between Topic 321, Topic 323, and Topic 815." The amendments in ASU 2020-01 clarify the interaction of the accounting for equity securities under Topic 321 and investments accounted for under the equity method of accounting. The ASU is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. Early adoption is permitted. The Company is assessing what impact ASU 2020-01 will have on the Condensed and Consolidated Financial Statements. In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." This ASU provides temporary optional expedients and exceptions for applying GAAP to contract modifications, hedging relationships and other transactions if certain criteria are met in order to ease the potential accounting and financial reporting burden associated with the expected market transition away from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. The ASU is currently effective and may be applied prospectively at any point through December 31, 2022 at the Company’s option. The Company is assessing what impact ASU 2020-04 will have on the Condensed and Consolidated Financial Statements.
