Abstract
A lock section is mechanically operated by a key provided with identification information to perform a locking or unlocking operation. A receiver acquires the identification information from the key. A checker determines whether the identification information acquired by the receiver matches with pre-stored registration information of the key. A limiter restricts the unlocking operation of the key when the checker determines that the identification information does not match with the registration information.
