In addition, when a first ID code signal corresponding to the vehicle-side request signal is input from the vehicle-side transmission / reception unit 31, the vehicle-side microcomputer 32 performs a decoding process on the first ID code signal and the first ID code signal. Is collated with the first ID code recorded in the memory 32a (ID code collation). As a result, when both the first ID codes match, that is, when the ID code verification is established, the vehicle-side microcomputer 32 drives the door lock driving device 35 to unlock the door lock or permits the engine to start. To do. Specifically, if the first ID code signal is transmitted in response to the request signal transmitted to the periphery of the vehicle, the vehicle-side microcomputer 32 outputs a drive signal to the door lock drive device 35 to lock the door lock. Unlock. Moreover, if the 1st ID code signal is transmitted in response to the request signal transmitted in the vehicle interior, the vehicle side microcomputer 32 will make an engine startable state. Therefore, the engine starts when the start switch 33 is operated in this state. In other words, when the engine start permission state is not set, the engine is not started even if the start switch 33 is operated. In this embodiment, the engine can be started only when the shift position sensor 34 is in the “P” range or the “N” range.
