ABSTRACT:
A data input device for beforehand inputting ID data into a locking device in a locking system, including a data input unit for generating data to be preset in the locking device, an IC key type of connector which is connected to the data input unit and has the same shape as an IC key, serving as an interface like the IC key, and through which data can be supplied from the data input unit to the locking device, and a lock control unit provided in the locking device, for receiving and storing the data supplied from the data input unit when the IC key type of connector is inserted into a reader/writer of the locking device. When the stored ID data is coincident with ID data transmitted from the IC key, the lock control unit releases the lock of the locking device.
