Abstract
A remote controlled lock system (100) includes a computer (111), a system controller (102), a transmitter (109), and at least one remote controlled lock device (105). The system controller (102) generates one of a digital lock or unlock code upon a change of a user access condition of the computer (111). The transmitter (109) transmits a radio signal including the lock code or the unlock code, and a selective call receiver address. The remote controlled lock device (105) includes a selective call receiver (310) and an electromechanical lock (311). The electromechanical lock (311) has a locking member (1205) which is switched to a mechanically stable lock or unlock position in response to the lock or unlock code when the radio signal when the transmitted selective call receiver address matches a predetermined address stored in the selective call receiver (310).
