ABSTRACT:
The invention provides an ignition key-vehicle communication device having at least one electronic key which can be inserted into a vehicle-end ignition lock. A wireless key-vehicle communication component arranged on the key actuates at least one vehicle-end functional unit by activating an activation element which is arranged at the key end. To protect against incorrect operation, means are provided for detecting when a key is inserted into the ignition lock and/or is inserted in a specific position in the ignition lock, and disabling communication between this key and the functional unit to be actuated in response thereto. The means for protecting against incorrect operation are arranged on the key.
