Organization, Consolidation and Presentation of Financial Statements [Abstract]
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS Recently Adopted Accounting Pronouncements: In October 2021, the FASB issued ASU No. 2021-08, "Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers." This ASU requires contract assets and contract liabilities (e.g. deferred revenue) acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC 606, "Revenue from Contracts with Customers". Generally, this new guidance will result in the acquirer recognizing contract assets and contract liabilities at the same amounts recorded by the acquiree. Historically, such amounts were recognized by the acquirer at fair value in purchase accounting. This ASU is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted, including in interim periods, for any financial statements that have not yet been issued. The Company elected to early adopt ASU 2021-08 on January 1, 2022, and will apply this new guidance to all business combinations consummated subsequent to this date.

Fair Value Measurements

Fair Value Measurements	3 Months Ended

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 March 31, 2022, 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 $ — $ 22.5 $ — $ 22.5 Total asset recurring fair value measurements $ — $ 22.5 $ — $ 22.5 Liabilities: Deferred compensation and other retirement plans $ — $ 22.7 $ — $ 22.7 Total liability recurring fair value measurements $ — $ 22.7 $ — $ 22.7 Financial instruments not carried at fair value Total debt $ — $ 1,418.6 $ — $ 1,418.6 Total financial instruments not carried at fair value $ — $ 1,418.6 $ — $ 1,418.6 Assets and liabilities measured at fair value at December 31, 2021, 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 $ — $ 24.5 $ — $ 24.5 Total asset recurring fair value measurements $ — $ 24.5 $ — $ 24.5 Liabilities: Deferred compensation and other retirement plans $ — $ 25.9 $ — $ 25.9 Total liability recurring fair value measurements $ — $ 25.9 $ — $ 25.9 Financial instruments not carried at fair value Total debt $ — $ 1,510.4 $ — $ 1,510.4 Total financial instruments not carried at fair value $ — $ 1,510.4 $ — $ 1,510.4 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. • 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 these debt instruments is obtained based on observable market prices quoted on public exchanges for similar instruments. The methodologies used by the Company to determine the fair value of its financial assets and liabilities at March 31, 2022, are the same as those used at December 31, 2021. The carrying values of Cash and cash equivalents, Accounts and notes receivable, net, 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 also had investments in debt and equity securities without readily determinable fair values of $35.8 million as of both March 31, 2022 and December 31, 2021, which are classified as Other noncurrent assets within the Condensed and Consolidated Balance Sheets. These investments are considered to be nonrecurring fair value measurements, and thus, are not included in the fair value tables above.

Share-based Payment Arrangement, Noncash Expense [Abstract]
Share-Based Compensation	SHARE-BASED COMPENSATION The Company’s share-based compensation plans include programs for stock options, restricted stock units ("RSUs"), performance stock units ("PSUs") and deferred compensation. 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 months ended March 31: In millions 2022 2021 Stock options $ 2.9 $ 2.8 RSUs 7.3 5.6 PSUs 1.6 1.3 Deferred compensation (1.1) 0.4 Pre-tax expense 10.7 10.1 Tax benefit (0.9) (1.1) After-tax expense $ 9.8 $ 9.0 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 three months ended March 31 were as follows: 2022 2021 Number Weighted- Number Weighted- Stock options 157,880 $ 28.59 179,743 $ 24.99 RSUs 101,609 $ 115.33 117,864 $ 109.49 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 three months ended March 31: 2022 2021 Dividend yield 1.42 % 1.32 % Volatility 27.05 % 27.14 % Risk-free rate of return 1.89 % 0.75 % Expected life (years) 6.0 6.0 Volatility is based on the Company’s historic volatility. 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 During the three months ended March 31, 2022, the Company granted PSUs with a maximum award level of approximately 0.1 million shares. In February 2020, 2021 and 2022, 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 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.

The increase in the effective tax rate compared to 2021 is primarily due to the unfavorable mix of income earned in higher tax rate jurisdictions, which is partially offset by the favorable year-over-year change in the amounts recognized for uncertain tax positions.

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 months ended March 31: In millions 2022 2021 Weighted-average number of basic shares 88.2 90.7 Shares issuable under share-based compensation plans 0.4 0.5 Weighted-average number of diluted shares 88.6 91.2 At March 31, 2022, 0.3 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.

Segment Reporting [Abstract]
Business Segment Information	BUSINESS SEGMENT INFORMATIONThe Company classifies its business into the following two reportable segments based on industry and market focus: Allegion Americas and Allegion International. The Company largely evaluates performance based on Segment operating income and Segment operating margins. Segment operating income 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 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 to arrive at a Segment operating income 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 as a percentage of the segment’s Net revenues. A summary of operations by reportable segment for the three months ended March 31 was as follows: In millions 2022 2021 Net revenues Allegion Americas $ 528.2 $ 498.9 Allegion International 195.4 195.4 Total $ 723.6 $ 694.3 Segment operating income Allegion Americas $ 123.9 $ 135.4 Allegion International 19.6 15.4 Total 143.5 150.8 Reconciliation to Operating income Unallocated corporate expense (26.5) (19.5) Operating income 117.0 131.3 Reconciliation to earnings before income taxes Interest expense 11.9 12.3 Other income, net (2.2) (3.5) Earnings before income taxes $ 107.3 $ 122.5

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 As of March 31, 2022 and December 31, 2021, the Company has recorded reserves for environmental matters of $15.4 million and $16.4 million, respectively. The total reserve at March 31, 2022 and December 31, 2021, included $3.6 million and $4.3 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 the timing of their expected future payment. The Company’s total current environmental reserve at March 31, 2022 and December 31, 2021, was $ 3.1 million and $3.7 million, respectively, and the remainder is classified as noncurrent. Expenses related to environmental remediation were not material during either the three months ended March 31, 2022 or 2021. Given the evolving nature of environmental laws, regulations and technology, the ultimate cost of future compliance is uncertain. Warranty Liability The changes in the standard product warranty liability for the three months ended March 31 were as follows: In millions 2022 2021 Balance at beginning of period $ 17.7 $ 16.5 Reductions for payments (2.4) (1.8) Accruals for warranties issued during the current period 3.1 3.5 Changes to accruals related to preexisting warranties — (0.1) Currency translation (0.1) (0.1) Balance at end of period $ 18.3 $ 18.0 Standard product warranty liabilities are classified as either Accrued expenses and other current liabilities or Other noncurrent liabilities within the Condensed and Consolidated Balance Sheets based on the timing of the expected future payments.

The dividend is payable June 30, 2022, to shareholders of record on June 16, 2022. Acquisition Agreement On April 22, 2022, the Company signed a definitive agreement to acquire Stanley Access Technologies LLC ("Access Technologies") and assets related to the automatic entrance solutions business from Stanley Black & Decker, Inc. for $900 million in cash. Access Technologies is a leading manufacturer, installer and service provider of automatic doors in the U.S. and Canada. Its diversified customer base centers on non-residential settings, including retail, healthcare, education, commercial offices, hospitality and government. Access Technologies generated approximately $340 million in Net revenues in 2021. The planned acquisition will create a more comprehensive portfolio of access solutions, with the addition of automated entrances. Additionally, Access Technologies will add an expansive service and support network throughout the U.S. and Canada, broadening the Company's solutions to better serve a breadth of national, regional and local customers, and complementing the Company's existing strengths in these non-residential markets. The acquisition will help progress the Company's strategy to create value "by securing people and assets with seamless access wherever they reside, work and thrive." Access Technologies is expected to be integrated into the Allegion Americas segment. The Company intends to finance the transaction through a combination of cash, borrowings under its existing 2021 Revolving Facility and new debt financing. The Company has obtained fully committed financing, and the anticipated acquisition is not subject to a financing condition. The acquisition is expected to close in the third quarter of 2022, subject to regulatory approval and customary closing conditions.

Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS Recently Adopted Accounting Pronouncements: In October 2021, the FASB issued ASU No. 2021-08, "Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers." This ASU requires contract assets and contract liabilities (e.g. deferred revenue) acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC 606, "Revenue from Contracts with Customers". Generally, this new guidance will result in the acquirer recognizing contract assets and contract liabilities at the same amounts recorded by the acquiree. Historically, such amounts were recognized by the acquirer at fair value in purchase accounting. This ASU is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted, including in interim periods, for any financial statements that have not yet been issued. The Company elected to early adopt ASU 2021-08 on January 1, 2022, and will apply this new guidance to all business combinations consummated subsequent to this date.
