I have a 96 Audi A4 Quattro. I have a little blck button on the key and have no idea what it does. Anybody know? The car doesnt seem to do anything when i push it. Did these cars come withsome sort of alarm or keyless entry? It would be cool to have keyless entry.

 

It is a flashlight, check the front and you should see a little hole where the bulb is. It takes a watch batery, but I don't use it. LED's are better. I have been trying to figure a way to retrofit an LED in there but haven't found a way yet.

 

It is for the ejector seat
