EXHIBIT 10.51

                                SECOND AMENDMENT
                                 TO THE KEYCORP
                          SUPPLEMENTAL RETIREMENT PLAN

      WHEREAS, KeyCorp has established the KeyCorp Supplemental Retirement Plan
(the "Plan"), and

      WHEREAS, the Board of Directors of KeyCorp has authorized its Compensation
Committee to permit amendments to the Plan, and

      WHEREAS, the Compensation Committee of the Board of Directors of KeyCorp
on September 16, 2004 determined it desirable to amend the Plan and accordingly
authorized the execution of this Second Amendment,

      NOW, THEREFORE, pursuant to such action of the Compensation Committee, the
Plan is hereby amended as follows:

      1.    ARTICLE II, Section 2.1(c) shall be amended to include the term
"Equity/Compensation Award" as a new definition to the Plan, with all remaining
Sections under Article II thereafter sequentially renumbered:

            "2.1(c) "EQUITY/COMPENSATION AWARD" shall mean one-half (50%) of the
            value of an award granted under the KeyCorp 2004 Equity Compensation
            Plan for any Plan year. The term "Equity/Compensation Award" may
            include "Stock Appreciation Rights", "Restricted Stock", "Restricted
            Stock Units", "Performance Shares", and/or "Performance Units", but
            shall specifically not include "Options" as those terms have been
            defined in accordance with the provisions of the KeyCorp 2004 Equity
            Compensation Plan."

      2.    Article II, Section 2.1(l) shall be amended to delete it in its
entirety and to substitute therefore the following:

            "2.1(l) "INCENTIVE COMPENSATION AWARD" for any Plan year shall
            collectively mean the short term incentive compensation award
            (whether in cash or common shares of the Corporation, and whether
            paid or deferred, or a combination of both) and the long term
            incentive compensation award (whether in cash or common shares of
            the Corporation, and whether paid or deferred, or a combination of
            both) (if any) granted to a Grandfathered Employee under an
            Incentive Compensation Plan, as follows:

            -     An incentive compensation award granted under the KeyCorp
                  Annual Incentive Plan, the KeyCorp Short Term Incentive
                  Compensation Plan, the KeyCorp Management Incentive
                  Compensation Plan, and/or such other Employer-sponsored line
                  of business Incentive Compensation Plan which shall constitute
                  an Incentive Compensation Award for the year in which the
                  award is earned (without regard to the actual time of
                  payment).

            -     An incentive compensation award granted under the KeyCorp Long
                  Term Incentive Compensation Plan ("LTIC Plan") with respect to
                  any multi-year performance period which shall be deemed to be
                  for the last year of the multi-year period without regard to
                  the actual time of payment of the award. Accordingly, an
                  incentive compensation award granted under the LTIC Plan with
                  respect to the three-year performance period of 1993, 1994,
                  and 1995 will be deemed to be for 1995 (without regard to the
                  actual time of payment), and the entire incentive compensation
                  award under the LTIC Plan for that performance period will be
                  an Incentive Compensation Award for the year 1995.

            -     An incentive compensation award granted under the KeyCorp Long
                  Term Incentive Plan ("Long Term Plan") with respect to any
                  multi-year period which shall be deemed to be for the last
                  year of the multi-year performance period and for the year
                  immediately following such year (without regard to the actual
                  time of payment). Accordingly, an award granted under the Long
                  Term Plan with respect to the four-year performance period of
                  1998, 1999, 2000, and 2001 shall be deemed to be for the years
                  2001 and 2002, with one-half the award allocated to the year
                  2001, and one-half the award allocated to the year 2002.



            -     An incentive compensation award granted in the form of
                  restricted stock under the KeyCorp Amended and Restated 1991
                  Equity Compensation Plan with respect to any multi-year period
                  (but specifically excluding those awards applicable to the
                  2002-2003 multi-year period), which shall be deemed to be for
                  the year in which the award (grant) is made to the
                  Grandfathered Employee; provided, however, that only those
                  shares of restricted stock that have vested as of the
                  Grandfathered Employee's termination date shall be utilized
                  for purposes of determining the Grandfathered Employee's
                  Incentive Compensation Award. The fair market value of such
                  shares as of the date of the restricted stock grant multiplied
                  by the number of vested shares as of the Grandfathered
                  Employee's termination date shall be included in determining
                  the value of such award for purposes of calculating the
                  Grandfathered Employee's Supplemental Retirement Benefit under
                  the provisions of Article III of the Plan.

                  Notwithstanding the foregoing, however, in calculating the
                  Grandfathered Employee's Supplemental Retirement Benefit under
                  the provisions of Article III of the Plan, if it is determined
                  that an incentive compensation award granted under the KeyCorp
                  Amended and Restated 1991 Equity Compensation Plan would
                  produce a larger Plan benefit for the Grandfathered Employee
                  if the award was included in the year in which the award (or
                  any part of the award) was initially vested rather than in the
                  year in which the award was granted, then such incentive
                  compensation award shall be included for the year in which the
                  award (or any part of the award) initially vested rather than
                  for the year in which the award was granted.

                  If at the time of the Grandfathered Employee's termination
                  date, the Grandfathered Employee maintains shares of not
                  forfeited restricted stock and such restricted stock later
                  vests in conjunction with the passage of time or with the
                  Corporation's attainment of certain performance criteria, or
                  otherwise, then as of such subsequent vesting date the
                  Grandfathered Employee's Monthly Supplemental Retirement
                  Benefit shall be recalculated to include such newly vested
                  shares. Such newly vested shares shall relate to the award in
                  which such shares were granted under the KeyCorp Amended and
                  Restated 1991 Equity Compensation Plan and shall be included
                  as a part of that award (based on either the date of grant or
                  the date of initially vesting, whichever date was actually
                  used by the Plan in calculating the Grandfathered Employee's
                  initial Monthly Supplemental Retirement Benefit).

            -     An incentive compensation award granted in the form of either
                  restricted stock and/or phantom shares (hereinafter
                  collectively referred to as "shares") under the KeyCorp Chief
                  Executive Officer Plan with respect to any multi-year period
                  (but specifically excluding those awards applicable to the
                  2002-2003 multi-year period), shall be deemed to be for the
                  year in which the award (grant) is made to the Grandfathered
                  Employee; provided, however, that only those shares that have
                  vested as of the Grandfathered Employee's termination date
                  shall be utilized in calculating the Grandfathered Employee's
                  Incentive Compensation Award. The fair market value of such
                  shares as of the date of the share grant multiplied by the
                  number of vested shares as of the Grandfathered Employee's
                  termination date shall be used in determining value of such
                  award for purposes of calculating the Grandfathered Employee's
                  Supplemental Retirement Benefit under the provisions of
                  Article III of the Plan.

            -     Notwithstanding the foregoing, however, in calculating the
                  Grandfathered Employee's Supplemental Retirement Benefit under
                  the provisions of Article III of the Plan, if it is determined
                  that an incentive compensation award granted under the KeyCorp
                  Chief Executive Officer Plan would produce a larger Plan
                  benefit for the Grandfathered Employee if the award was
                  included in the year in which the award (or any part of the
                  award) initially vested rather than in the year in which the
                  award was granted, then such incentive compensation award
                  shall be included in year in which the award (or any part of
                  the award) initially vested rather than for the year for which
                  the award was granted.

                  If at the time of the Grandfathered Employee's termination
                  date, the Grandfathered Employee maintains not forfeited
                  shares, and such shares later vest in conjunction with



                  the passage of time or with the Corporation's attainment of
                  certain performance criteria, or otherwise, then as of such
                  subsequent vesting date, the Grandfathered Employee's Monthly
                  Supplemental Retirement Benefit shall be recalculated to
                  include such newly vested shares. Such newly vested shares
                  shall relate to the award in which such shares were granted
                  under the under the KeyCorp Chief Executive Officer Plan, and
                  shall be included as part of that award (based on either the
                  date granted or the date initially vested, whichever date was
                  actually used by the Plan in calculating the Grandfathered
                  Employee's initial Monthly Supplemental Retirement Benefit).

            -     For those Grandfathered Employees who, for Plan purposes,
                  received Incentive Compensation Award(s) granted in the form
                  of time-lapsed restricted stock award(s) and/or performance
                  shares under the KeyCorp Amended and Restated 1991 Equity
                  Compensation Plan or the KeyCorp Chief Executive Officer Plan
                  with respect to any multi-year period, the term Incentive
                  Compensation Award shall also include those
                  Equity/Compensation Award(s) granted to the Grandfathered
                  Employee under the 2004 Equity Compensation Plan. An
                  Equity/Compensation Award shall be deemed to be for the year
                  in which the Equity/Compensation Award vests. If the
                  Equity/Compensation Award is in the form of Restricted Stock,
                  Restricted Stock Units, Performance Units or Performance
                  Shares, the fair market value of such shares as of the date of
                  the Equity/Compensation Award grant multiplied by the number
                  of vested shares as of the Grandfathered Employee's
                  termination date shall determine the value of such Incentive
                  Compensation Award for purposes of calculating the
                  Grandfathered Employee's Supplemental Retirement Benefit under
                  the provisions of Article III of the Plan.

      Notwithstanding the foregoing provisions of this Section 2.1(l) hereof, in
calculating a Grandfathered Employee's Incentive Compensation Award for any 12
month period, there shall be included only one award granted under the KeyCorp
Amended and Restated 1991 Equity Compensation Plan, the KeyCorp Chief Executive
Officer Plan, or Equity/Compensation Award under the KeyCorp 2004 Equity
Compensation Plan for purposes of determining such Incentive Compensation Award
for such 12 month period.

      3.    Article II, Section 2.1(m) shall be amended to delete it in its
entirety and to substitute therefore the following:

            "2.1(m) "INCENTIVE COMPENSATION PLAN" shall mean the KeyCorp
            Management Incentive Compensation Plan, the KeyCorp Annual Incentive
            Plan, the KeyCorp Short Term Incentive Compensation Plan, the
            KeyCorp Long Term Incentive Compensation Plan, the KeyCorp Long Term
            Incentive Plan, the KeyCorp Amended and Restated 1991 Equity
            Compensation Plan, the KeyCorp Chief Executive Officer Plan, the
            KeyCorp 2004 Equity Compensation Plan, and/or such other Employer or
            KeyCorp-sponsored incentive compensation plan that KeyCorp in its
            sole discretion determines constitutes an "Incentive Compensation
            Plan" for purposes of this Section 2.1(m), as may be amended from
            time to time."

      4.    Article III, Section 3.4 shall be amended to delete it in its
entirety and to substitute therefore the following:

            "3.4 RECALCULATION AS A RESULT OF HARMFUL ACTIVITY. Notwithstanding
            the foregoing provisions of Section 3.2 and Section 3.3 hereof, the
            Corporation reserves the right at all times to recalculate a
            Grandfathered Employee's Supplemental Retirement Benefit, if it is
            determined that within six months of the Grandfathered Employee's
            termination date the Grandfathered Employee engaged in any Harmful
            Activity, as that term is defined in accordance with Section 2.1(k)
            of the Plan, which resulted in the forfeiture of all or any portion
            of the Grandfathered Employee's restricted share award(s) under the
            KeyCorp Amended and Restated 1991 Equity Compensation Plan or the
            KeyCorp Chief Executive Officer Plan, or Equity/Compensation Awards
            granted under the KeyCorp 2004 Equity Compensation Plan. Such
            recalculation shall relate back to the Grandfathered Employee's
            original date of termination, and any Supplemental Retirement
            Benefit payment paid to the Grandfathered Employee in excess of such
            recalculated Supplemental Retirement Benefit amount shall be offset
            against any future Supplemental Retirement Benefit payments to be
            paid to the Grandfathered Employee."

      5.    The amendment set forth in Paragraphs 1 through 4 shall be effective
as of September 16, 2004.



      6.    Except as otherwise amended herein, the Plan shall remain in full
force and effect.

      IN WITNESS WHEREOF, KeyCorp has caused this Second Amendment to the Plan
to be executed by its duly authorized officer to be effective as of the
sixteenth day of September 2004.
