A secure access system includes at least one lock, at least one electronic key with stored information assigned to a user and a system administration for administering user access privileges. A method for remotely updating the user's expired access privileges includes establishing communication between the user and the system administration from a location remote from the system administration, receiving a remote privilege code from the system administration, communicating the remote privilege code to the lock, and, if authorized, the lock validating the privilege code to renew the user's access privileges. The validated privilege code can also be made effective to access other different locks within the system.

Remote access privileges renewal

An electronic security enclosure conceals a device, such as a switch, valve, outlet, or lock, behind a movable member. When the movable member is unlocked, by an electronic key, and moved to reveal the concealed device, the key is captured, preventing its removal until the enclosure is again secured over the device. A variety of operational features, including provision for keyholder access restrictions, time-of-day restrictions, provision of different classes of keys for employees and vendors, etc., are also provided. The invention also contemplates a plurality of access control devices, including lock boxes, padlocks, mortise locks, cam locks, etc., that are each operable by a common electronic key.
