Abstract
An electronic key executes keyless entry communication or RFID communication. A wireless controller mounted on a vehicle executes keyless entry communication within a range of a radius of several meters to several tens of meters. An RFID reader is assigned to each door and executes RFID communication within a range of a radius of approximately 1 meter. In regards to unlocking the door, the wireless controller issues a password by the keyless entry communication, and a wireless circuit temporarily stores the issued password. The RFID readers search for the password stored in the electronic key by the RFID communication, and the wireless controller unlocks a door corresponding to the RFID reader for which the password was detected.
