Lock key for automobile locking system has microwave lock code signal generation and/or evaluation device with key shaft acting as microwave antenna

摘要

The lock key (1) has a key housing (5) of an electrically non-conductive material and a relatively pivoted electrically conductive key shaft (4) which can be inserted in the lock, for mechanical and/or magnetic operation of the lock mechanism. The key shaft acts a reception antenna for microwave signals, the key housing containing a device (8) for generation and/or evaluation of microwave lock code signals.
