Abstract

An apparatus and a method for use with an electronic locking system is provided. At least one key is selected in order to have access to at least one lock. This key to lock relationship is transferred to a memory of the key. The key is presented to the lock and at least a portion of the key to lock relationship from the key is transferred to a memory of the lock. This transfer updates the memory of the key to lock relationships in the lock. The update of the memory in the lock is noted in the memory of the key. The key may then be placed in communication with a computer so that at least a portion of the memory of the key is transferred to a database in the computer. This transfer updates the database in order to reflect the fact that the memory of the lock has been updated and completed.
