A signal is received from a key having predetermined information. A resulting output signal is discriminated as to whether it represents the predetermined information. A predetermined anti-theft operation is actuated in response to output signals from first and second detectors indicating that at least one predetermined one of the covering members is closed and locked. Operation of the actuator is disabled in response to an output signal indicating that the received signal represents the predetermined information. The key includes a magnetic element forming first predetermined information, and light emitting elements for emitting infrared ray carrying second predetermined information. The predetermined anti-theft operation is actuated in response to an output signal from a third detector indicating that the key has been removed from a predetermined key hole, in addition to the output signals from the first and second detectors. |
