Remote-control-operated locking/unlocking system

摘要

A remote-control-operated locking/unlocking system includes a key which transmits a locking/unlocking signal by remote control. A locking/unlocking unit is provided with a controller for controlling a locking/unlocking operation based on a locking/unlocking signal transmitted from the key. The controller has a suitability determining section for determining the suitability of a locking/unlocking signal transmitted from the key, and an information section for providing information indicating that the use of the key is unsuitable.
