Many of the banks that issued these portable safes kept the key and opened it for you when you came in to deposit the money into your account, which would explain the scarcity of keys out there.
The chromed plate was customized with the bank's name and their depositor's account number and then riveted to the exterior of the bank prior to shipment by the Automatic Recording Safe Co.
