  • Patent number: 5878613
    Abstract: A key control device comprises an access key and lock, and a stored key and lock. The access lock operably receives the access key and is keyed such that when the access key is inserted into the access lock, it becomes movable between an access key release state and an access key capture state. The stored lock operably receives the stored key and is keyed such that when the stored key is received by the stored lock it becomes movable between a stored key release state and a stored key capture state. Only one key can be removed at any given time from either lock and such removal locks the other key against removal so that it is retained by the key control device. The access and stored lock are totally independent and not interconnected in any way.
