Abstract
An in-vehicle device remote control system includes a vehicle-side device, a main mobile device that returns a first response signal in response to a request signal transmitted from the vehicle-side device, and a sub-mobile device that returns a second response signal in response to the request signal. When the vehicle-side device receives the response signal, it conducts a matching process. Vehicle doors are unlocked automatically when the received response signal is determined to be either the first or the second response signal. On the other hand, the engine start is permitted only when the received signal is determined to be the first response signal.
