ABSTRACT:
The invention provides a key/vehicle communication device in which an electronic key capable of being inserted into a steering-column lock controls activation of an immobilizing device having an inductive key/steering-column lock communication channel for recognizing whether a key authorized for use is inserted. A key/vehicle communication channel is also provided, for the remotely controllable activation of at least one vehicle-side function via a key-side actuating member. A vehicle-side control unit determines, via the inductive key/steering-column lock communication channel, whether a key authorizing the driving of a vehicle is inserted in the steering-column lock and, if so, blocks the vehicle-side part of the key/vehicle communication channel.
