I have a 2003 A6 quattro that I purchased last August that now has 80K miles. I have begun to experience problems with my central locking system. The remote control key quit working. I can still manually lock and unlock the car with the key, just not with the remote. I tried to use the spare key remote and it would not work either. I then bought new batteries for the remote keys and still no go. What do I try next? I miss using the keyless entry. I am fortunate that everything with the central locking system still works perfect except for the remote control keyless entry. Is there a receiver for the remote that needs to be checked/replaced? Does the main control unit need to be replaced? I don't know where the receiver or control unit are located. Any help would be much appreciated! This car rocks and I have not had any other problems! Thanks

 

You probably just need to reprogram the remotes to work with your car. When the batteries die or you change them you have to reprogram the remotes. I know on my 00 (without immobilzer) there is directions in my owners manual. If not the dealer can do it, maybe for no charge if they like you.

Thanks man. I had to change my car battery about the same time this started. The car battery had gone bad. I also put new batteries in the remote keys. I bet you are right on the money. I didn't even think about that. So, I can reprogram the keys myself? That would be great!
