Abstract

A vehicle security system has an access monitoring device which includes an access control part and/or an electronic immobilizing device which comprises an immobilizer control part, located on the vehicle. An authentication device can be carried by the user for actuation, subject to authentication, of the respective control part on the vehicle via an associated wireless actuation communication channel. Both an actuation communication channel which needs a key, and a wireless actuation communication channel which needs no key (and communicates based on proximity, without manual actuation) are provided for actuating a control part on the vehicle, optionally via one or the other actuation communication channel. The actuation communication channel which requires a key is given priority over the corresponding actuation communication channel which needs no key.
