<p>Keyholders (22) for controlled keys mate with corresponding portions of keyholder housings (21) in a storage container (20). A latch releases a keyholder only upon receiving an access signal. A data processor (14) receives inputs and provides access to selected keys in response to appropriate inputs. The data processor further records information such as the date and time of access. Keyholder housings include circuitry to determine when a key has been replaced. The data processor records this information. The data processor provides output reports listing information as to access, return, and usage. Keyholders may have unique identification codes that are read by circuitry in the storage container or data processor. The data processor then records usage and controls access via the keyholder identification codes.</p> |
