Obtain a Lost Combination
American Lock combination locks are registered to a particular business or school. Please see your administrator for the chart with lock serial numbers and corresponding combinations.
If you cannot locate your information, for locks with serial numbers ending with “A”, you may obtain a new combination chart. We ask that you mail your request on your official company or school letterhead along with the completed Chart Request Form. The cost for hardcopy charts or charts on disk is $50 (Note: If you need a full end user history, the cost is $100).
Please mail your request with your check or money order to the address below:
Attn: Customer Service/Chart Request 137 W Forest Hill Avenue
PO Box 927
Oak Creek, WI 53154
Please allow up to 4 to 6 weeks from receipt of your letter to process your request.
