Abstract

A security system for controlling access to a locked area and updating a lock code combination memory. A central console generates lock code combinations, encodes key cards, and stores the lock code combinations. Correspondence between an authorization code combination inputted into the console, and a valid, stored authorization code combination is required to operate the console. Each lock stores a guest, station and master lock code combination. The lock opens when correspondence occurs between an inputted lock code combination and one of the stored lock code combinations. The stored guest or station combinations may be altered when an appropriately coded key card is inserted in the lock. A portable temporary security override module (TSOM) receives a security code combination and a lock code combination from the central console to enable the TSOM to be used to either open the lock, lock or unlock a double lock, or update the lock code combination by changing the guest, station or master lock code combination. A portable permanent security override module (PSOM) operates similarly to a TSOM but is adapted to receive lock code combinations from a key card rather than from the console.
