American Locker Group Incorporated
608 Allen Street
Jamestown, New York  14702-1000

Ladies and Gentlemen:

         We are  counsel  to  American  Locker  Group  Incorporated,  a Delaware
corporation (the  "Registrant"),  and we have acted as counsel to the Registrant
in  connection  with the  Registrant's  Registration  Statement on Form S-8 (the
"Registration  Statement").  The Registration  Statement is to be filed with the
Securities  and Exchange  Commission and relates to the  registration  under the
Securities  Act of 1933,  as amended,  of an  aggregate  of 150,000  shares (the
"Shares")  of the  Registrant's  Common  Stock,  par value  $1.00 per share,  in
connection with the American Locker Group Incorporated 1999 Stock Incentive Plan
(the "Plan").

         We are familiar with the  Registration  Statement and the Plan,  and we
have examined the Registrant's Certificate of Incorporation and the Registrant's
By-Laws.  We have also  examined  such  other  public and  corporate  documents,
certificates,  instruments and corporate records,  and such questions of law, as
we have deemed necessary or appropriate for the purpose of this opinion.

         Based on the  foregoing,  we are of the opinion  that the Shares,  when
issued in accordance  with the Plan,  will be duly  authorized,  validly issued,
fully paid and nonassessable.

         We hereby  consent to the filing of this  opinion as Exhibit 5.1 to the
Registration Statement.

                                        Yours truly,


                                        /s/ Kirkpatrick & Lockhart LLP
