Quoted service for a warehouse operation a few days ago (we provide office cleaning Phoenix). in running through our key security procedures, I mentioned picking up a string of credit unions from a franchise janitorial provider a bit ago; I had to visit each credit union location in the afternoon to pick up the keys that the ma & pa franchisee had dropped off that morning.
In several of the locations, the keys returned by the franchisee had little sticky tags on the keys - client address on one side, alarm code on the other. Quite convenient for the janitor, but a bit of a security issue for the client, should the keys ever escape the janitor's grasp.
I talked through, and provided documentation, on our key procedures: no identification, save an internal account number, ever allowed on client keys; keys copied onto neutered bow blanks, to make unauthorized duplication difficult; keys kept separate from client name and address; alarm code printed on a card separate from client name or address; client name and address never along with the janitor, once he had memorized them. So, when we drop the keys in the Circle K parking lot, we've got a problem, but not as big a problem as we'd have with the client name, or alarm code, attached.
The potential commercial cleaning Phoenix client was amused, and seemed to appreciate our security procedures.
So, several days later, when I dropped by to pick up the keys dropped off that morning by the former janitorial service, my new client sported a bit of a grimace as he handed me the keys as turned in by the previous janitor - with the alarm code attached.
