ITEM 1.  SECURITY AND ISSUER.

         This statement (the "Statement") relates to the common stock, par value
$.001 per share (the "Union Common Stock"), of Union Bankshares, Ltd., a
Delaware corporation (the "Company" or "Union").

         The address of the principal executive office of the Company is: Union
Bankshares, Ltd., 1825 Lawrence Street, Suite 444, Denver, Colorado 80202.

ITEM 2.  IDENTITY AND BACKGROUND.

         The principal business address of KeyCorp, an Ohio corporation
("Keycorp"), is: 127 Public Square, Cleveland, Ohio 44114-1306. Keycorp is a
bank holding company and a financial holding company offering through its
subsidiaries a wide range of retail and commercial banking, commercial leasing,
investment management, consumer finance and investment banking products and
services to individual, corporate and institutional clients.

         (a)-(c); (f) The name, business address, present principal occupation
or employment, and the name and principal business of any corporation or other
organization in which such employment is conducted of each of the directors and
executive officers, as applicable, of Keycorp is set forth in Exhibit A hereto.
Except as otherwise indicated in Exhibit A hereto, each person listed in Exhibit
A hereto is a citizen of the United States.

         (d)-(e) During the last five years, none of Keycorp or, to the
knowledge of Keycorp, any of the persons listed on Exhibit A hereto, (i) has
been convicted in a criminal proceeding (excluding traffic violations or similar
misdemeanors) or (ii) has been a party to a civil proceeding of a judicial or
administrative body of competent jurisdiction and as a result of such proceeding
was or is subject to a judgment, decree or final order enjoining future
violations of, or prohibiting or mandating activities subject to, Federal or
State securities laws, or finding any violation with respect to such laws.

ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

         In order to induce Keycorp to enter into an Agreement and Plan of
Merger (the "Merger Agreement"), dated as of September 25, 2002, among the
Company, Keycorp, and Buffalo Acquiror Sub, Inc., a Delaware corporation and a
wholly owned subsidiary of Keycorp ("Acquiror Sub"), Charles R. Harrison, Bruce
E. Hall and Herman J. Zueck (the "Stockholders") entered into Voting and Support
Agreements, dated as of September 25, 2002 with Keycorp (each a "Voting
Agreement", and collectively, the "Voting Agreements") with respect to certain
shares of Union Common Stock beneficially owned by the Stockholders. No shares
of Union Common Stock were purchased by Keycorp pursuant to the Voting
Agreements, and thus no funds were used for such purpose. For a description of
the Voting Agreements, see "Item 4. Purpose of Transaction" below, which
description is incorporated herein by reference in response to


                                      -3-



this Item 3. Copies of the Voting Agreements are filed as Exhibits B, C, and D
hereto, and Exhibits B, C, and D are specifically incorporated herein by
reference in response to this Item 3.

ITEM 4.  PURPOSE OF TRANSACTION.

         (a)-(j) The purpose of Keycorp's entering into the Voting Agreements
covering the shares of Union Common Stock to which this Statement relates is to
facilitate the consummation of the transactions contemplated by the Merger
Agreement. Except as otherwise provided in this Statement, capitalized terms
that are used but not otherwise defined in this Statement shall have the meaning
assigned to such terms in the Merger Agreement, a copy of which is attached
hereto as Exhibit E and which is incorporated herein by reference in its
entirety.

         Pursuant to Instructions For Cover Page (2) to this Schedule 13D, the
following is a description of the relationship between Keycorp and the
Stockholders under the Voting Agreement but is not an affirmation by Keycorp of
the existence of a group for purposes of Section 13(d)(3) or Section 13(g)(3) of
the Securities Exchange Act of 1934 (the "Act") and Rule 13d-5(b)(1) thereunder.

         In order to induce Keycorp to enter into the Merger Agreement, the
Stockholders entered into the Voting Agreements with Keycorp. Pursuant to the
Voting Agreement, each of the Stockholders agreed, among other things, to vote
their Shares (as defined in the Voting Agreements) and any other shares of
capital stock of the Company acquired by them after the date of the Voting
Agreements and prior to the termination of the Voting Agreements, (i) in favor
of adoption of the Merger Agreement and any other action of the stockholders of
the Company requested in furtherance thereof, (ii) against any action or
agreement submitted for approval of the stockholders of the Company that would
result in a breach of any covenant, representation or warranty or any other
obligation or agreement of the Company contained in the Merger Agreement or of
the Stockholders in the Voting Agreements and (iii) against any Acquisition
Proposal or any other action submitted for approval to the stockholders of the
Company that is intended, or could reasonably be expected to, materially impede,
interfere or be inconsistent with, delay, postpone, discourage or materially and
adversely affect the Merger or the Voting Agreements.

         Under the Voting Agreements, each Stockholder agreed to grant to
Keycorp a proxy to vote the Shares owned beneficially and of record by such
Stockholder as indicated in the applicable Voting Agreement if such Stockholder
fails for any reason to vote such shares in accordance with the Voting
Agreement. In addition, each Stockholder agreed not to sell, transfer, pledge,
encumber, assign, distribute, gift or otherwise dispose of any of their Shares
or any Shares acquired by the Stockholders after the date of the Voting
Agreements.


                                      -4-



         The Voting Agreements will terminate upon the earlier of (i) the later
of (A) the termination of the Merger Agreement and (B) the date three months
from the date of the Voting Agreements and (ii) the Effective Time.

         The transactions contemplated by the Merger Agreement are summarized as
follows:

         On September 25, 2002, the Company, Keycorp and Acquiror Sub entered
into the Merger Agreement pursuant to which Acquiror Sub will merge with and
into Union, with Union as the surviving corporation of the merger (the
"Merger"). Pursuant to the Merger, each share of Union Common Stock outstanding
immediately prior to the Effective Time will be converted, subject to certain
customary exceptions, into the right to receive consideration comprising $22.63
in cash. Following consummation of the Merger, the Company will be a wholly
owned subsidiary of Keycorp.

         The Merger is subject to various conditions and regulatory approvals,
including prior approval of the Federal Reserve Bank and Colorado Division of
Banking, approval of the stockholders of the Company, and the satisfaction of
other customary terms and conditions in the Merger Agreement. Keycorp's
obligation to consummate the merger is also subject to the effectiveness of
certain employment agreements, separation and non-competition agreements and
waiver agreements with certain current officers and directors of the Company and
its banking subsidiary, Union Bank & Trust (the "Bank"), a Colorado state
chartered bank.

         Keycorp expects that subject to the receipt of regulatory approval and
the expiration of applicable waiting periods, it will merge the Bank with a
wholly owned banking subsidiary of Keycorp ("Keybank").

         The foregoing descriptions of the transactions contemplated by the
Voting Agreements and the Merger Agreement are qualified in their entirety by
reference to the respective agreements, copies of which are filed as Exhibits B,
C, D and E hereto, and such exhibits as specifically incorporated by reference
in response to this Item 4.

         Except as set forth in this Statement, the Voting Agreements and the
Merger Agreement, none of Keycorp or, to the best of Keycorp's knowledge, any of
the individuals named in Exhibit A hereto, has any plans or proposals which
relate to or which would result in or relate to any of the actions specified in
subparagraphs (a) through (j) of Item 4 of Schedule 13D.

ITEM 5.  INTERESTS IN SECURITIES OF THE ISSUER.

         (a) As a result of the Voting Agreements, Keycorp may be deemed to
beneficially own 846,022 shares of Union Common Stock which constitutes, based
upon information provided by the Company and set forth in the Merger Agreement,
approximately 35.10% of the outstanding shares of Union Common Stock. Keycorp,
however, hereby disclaims beneficial ownership of such shares of Union Common
Stock,


                                      -5-


and this Statement shall not be construed as an admission that Keycorp is, for
any or all purposes, the beneficial owner of the securities covered by this
Statement.

         Except as set forth in this Item 5, none of Keycorp or, to the best of
Keycorp's knowledge, any of the individuals named in Exhibit A hereto
beneficially own any shares of Union Common Stock.

         (b) Pursuant to the Voting Agreements, Keycorp may be deemed to have
shared power to vote 846,022 shares of Union Common Stock with the Stockholders.

         Keycorp may be deemed to share the power to vote 475,232 shares of
Union Common Stock with Charles R. Harrison. Charles R. Harrison is a United
States citizen whose business address is: 1825 Lawrence Street, Suite 444,
Denver CO 80202. His present principal occupation or employment is Chairman of
the Board and Chief Executive Officer of the Company.

         Keycorp may be deemed to share the power to vote 111,552 shares of

whose business address is: 1825 Lawrence Street, Suite 444, Denver CO 80202. His
present principal occupation or employment is Vice President, Treasurer,
Secretary and Director of the Company.

         However, Keycorp (i) is not entitled to any rights as a stockholder of
the Company as to the shares of Union Common Stock that are subject to the
Voting Agreements and (ii) disclaims any beneficial ownership of the shares of
Union Common Stock that are covered by the Voting Agreements.

         To the knowledge of Keycorp none of Charles R. Harrison, Herman J.
Zueck, and Bruce E. Hall, during the last five years, has been (i) convicted in
a criminal proceeding (excluding traffic violations or similar misdemeanors) or
(ii) a party to a civil proceeding of a judicial or administrative body of
competent jurisdiction and as a result of such proceeding was or is subject to a
judgment, decree or final order enjoining future violations of, or prohibiting
or mandating activities subject to, Federal or State securities laws, or finding
any violation with respect to such laws.

         (c) Except with respect to the transactions contemplated by the Voting
Agreements and the Merger Agreement which are described in response to Item 4
above and incorporated herein by reference, none of Keycorp or to the best of
Keycorp's knowledge, any of the individuals named in Exhibit A hereto, has
effected any transaction in Union Common Stock during the past 60 days. The
descriptions of the


                                      -6-


transactions contemplated by the Voting Agreements and the Merger Agreement, in
Item 4 are qualified in their entirety by reference to the respective agreements
and documents, as the case may be. Copies of the Voting Agreements are filed
hereto as Exhibits B, C and D and a copy of the Merger Agreement is filed hereto
as Exhibit E. Exhibits B, C, D and E are specifically incorporated herein by
reference in answer to this Item 5.

         (d) Except as set forth in this Item 5, no other person is known by
Keycorp to have the right to receive, or the power to direct the receipt of
dividends from, or the proceeds from the sale of, the Union Common Stock that
may be deemed to be beneficially owned by Keycorp.

         (e) Not applicable.

         WITH RESPECT TO THE SECURITIES OF THE ISSUER.
