Abstract
An immobilizing device for a motor vehicle includes an immobilizer control unit on the vehicle, one or more authentication elements which can be carried by the user, and an actuation communication channel for immobilizer actuation communications which require authentication, between the authentication element and the immobilizer control unit. The immobilizer control unit allows driving operation and/or engine starting only if the driving authorization check is positive. According to the invention, an immobilizer operating element arranged on the vehicle can be operated without any manipulation of an authentication element, for user-requested initiation of the immobilizer actuation communication processes which require authentication. Alternatively or additionally, the brake pedal can be used as an operating element for activating engine starting, once it has been enabled by the immobilizer control unit.
