Abstract

A security system for a storage compartment including a latch assembly disposed on an interior side of a door for latching the door in a closed position with the storage compartment. A plurality of reciprocating latch elements are included in the latch assembly for latching the door in a closed position with the storage compartment. A latch actuator included in the latch assembly moves the latch elements to latch the door. A master lock assembly controls operation of the latch actuator by having a first locking part of the master lock assembly interlocking with a second locking part carried by the latch actuator. A tamper-resistant master lock control controls operation of the master lock assembly from outside the storage compartment whereby access to the compartment interior is prevented when the latch assembly is latched and the master lock assembly is in the lock
