装置。 A key code transmitting means for transmitting a signal including predetermined key code information, a key code receiving means for receiving the signal, a key code included in the signal received by the key code receiving means, and a pre-stored key code. In a locking/unlocking device, the locking/unlocking device is provided with a key code verification means for comparing and verifying the key codes and outputting a locking/unlocking signal when both key codes match,
The lock/unlock device is characterized in that the key code is transmitted a plurality of times at predetermined time intervals, and the frequency of the carrier wave on which the key code is carried differs each time the key code is transmitted.
