Hi, I have 2002 A6 Avant. I had just one key, so I bought a blank on eBay with a remote. I cu the key and programmed the remote to open and close the vehicle but it would not start the car. Can someone tell me how do I reprogram it to start the car?
THanks you.

 

Dealer...........DO IT!

 

Yeah, I think the '02s and later have an immobilizer chip in them that requires dealer programming unfortunately.
