Abstract
An anti-theft system for a motor vehicle includes a portable code transmitter which transmits a code signal from a distance upon actuation. A receiver unit in the motor vehicle receives the code signal and evaluates it. Upon authorization, only the engine is started, but the vehicle does not have to be unlocked. A further code signal is required in order to drive the vehicle. However, it must be generated in the vehicle interior. Thus the engine can already warm up without the user being located in the vicinity of the vehicle.
