Abstract | A method and system is disclosed for allowing users to consolidate a large number electronic keys (for operating mechanical locks) in electronic key assemblies. These electronic keys are easily duplicated, added to, removed, backed up, or upgraded. The electronic key assemblies are also more resistant to tampering. The lock assembly and electronic key designs taught by the invention are customizable to meet various security needs. The lock assembly includes a transmitter and a receiver operatively coupled to an electronic circuit in communication with a store for keys. The electronic circuit is also coupled to the mechanical levers for operating the lock assembly. The electronic key assembly also has its transmitter, receiver, a control circuit and a user interface for selecting a particular electronic key password. |
