Re: Infrared V8 Key - www.AudiV8.com - Audi V8 Forum / Audi A8 Forum

Hi Dave,

since when do you have problems with your IR key?
There are several reasons:
1) The key is not synchronized with the car.
2) The key is damaged.
3) The IR sensors of your car are damaged.

1) When the battery of the car has been cut off for a longer period (few hours), the IR key is not longer synchronized with the car any longer. In this case you have to register the key at the control unit of your car. To do this, you put one of your keys into the lock for the ignition and switch it on (engine not started). After this close all doors of the car and lock the car on the driver site. The alarm system of your car will not respond as usual done by a short accustical signal. After you have locked the door with the second key you will have about five seconds to register the IR key. Therefore push the button on the IR key one to four times and wait about one second between each push. The car should respond to each push on the IR key with a short accustical signal. The memory for the keys has space for four keys. The number of the postion within the memory is given by the count of pushes while registration of the key. After you have registered the key, wait for about ten to thirty seconds and then try to open the car with the IR key.

2)Take a look on the IR-Diode of your key while pushing it. When you push it, the led should flash almost invisible and very short. Try this in a dark environment.

3)Do you know somebody who also drives a V8 with the IR system. Then try to register one of his keys, only for testing, at your car.

Best regards

Martin
