Abstract
An ignition lock system for a motor vehicle includes an electronic ignition key and an electronic ignition lock having a key receptacle. The electronic ignition key can be inserted into the key receptacle to exchange coded operating signals, the key receptacle, together with the inserted electronic ignition key, being movable out of an initial position into at least one operating position. A mechanical blocking device is provided in the key receptacle, which blocks the electronic ignition key against withdrawal from the key receptacle in the operating position. The mechanical blocking device cooperates with the electronic ignition key in such a way that the electronic ignition key and/or the key receptacle is irreversibly damaged when blocking actions of the mechanical blocking device are forcibly overcome.
