Advanced Key

From Wikipedia, the free encyclopedia

Advanced key is the electronic access and authorization system which is available as an option in several cars. The advanced key allows the driver to keep the car key in his or her pocket when unlocking and starting the automobile. The key is identified via a proximity sensor in the car door and a radio pulse generator in the key housing as soon as the driver is within approximately 1.5 metres of the vehicle. The vehicle is automatically unlocked as soon as the door handle (or trunk lid) is actuated.

The advanced key system also means that the steering is released and the ignition turned on electronically and without inserting the key in the ignition. The driver must have the key on his or her person inside the car for the engine can be started by pressing down on the brake followed by pressing the starter button. The advanced key also operates like a conventional Audi Huf key. When leaving a vehicle equipped with advanced key, it merely suffices to press the small locking button on the driver's door handle in order to lock the vehicle. The advanced key operates for 4 separate drivers and forms Audi's new personalization system, one-touch memory.
