Abstract
An anti-theft system for a vehicle that registers ID information at the time of replacement of a lock controller. A portable device, such as a key, has exclusive ID information. A lock controller locks or unlocks a control target device according to an authentication result of the portable device. An auxiliary controller transmits and receives data to and from the lock controller and stores the ID information of the portable device as backup data. The lock controller receives the ID information from the auxiliary controller, and transmits a response requiring signal for searching the portable device which has the ID information received from the auxiliary controller and is present within a predetermined detection range. Then, the lock controller stores the ID information of the portable device which has transmitted a response signal to the response requiring signal.
