Definitions
- the present invention relates to a vehicle key having a security element according to the preamble of claim 1, a corresponding security element according to the preamble of claim 1 1, and a method for operating a security element according to claim 12.
- Vehicle keys for motor vehicles such as a passenger car basically have the function, on the one hand, that an authorized person is guaranteed access to the vehicle by the vehicle key enabling the locking of the doors and the boot to be opened. Further, the vehicle key is used to start the engine of the vehicle.
- the comfort has been improved in that transceiver units have been integrated into the vehicle key in order to enable a long-range, for example radio-based, connection with transmitting and receiving units of the motor vehicle. This ensures that vehicle doors can be opened by means of a radio link without the user having to insert the key into a lock and manually turning a lock cylinder.
- modern vehicle keys also contain elements by means of which an electronic immobilizer can be realized in order to prevent a theft of the vehicle.
- electronic immobilizers are implemented by means of an RFID (Radio Frequency Identification), wherein such an RFID system has a transponder which is integrated in the vehicle key, and a reading device in the motor vehicle, by means of which a characteristic code of the transponder can be read.
