Default 2000 A8 remote key synchronization

Replaced the batteries in the backup key and ran the synchronization routine described on page 63 of the manual but did not work.

When I had the key apart I cleaned the contacts with alcohol, etc. and electronics looked OK.

Anyone have a solution? Feedback appreciated.

Default Try this...

I'll explain what the manual says, but in a plain-english fashion:


1. Take an extra key (not the one being programmed) and turn the ignition to "ON".

2. Get out, close the driver's door, and lock the car MANUALLY using the key you are programming

3. You said it is your backup key, so you should probably press the "LOCK" button twice. Your primary key is most likely in position one. You can assign up to four keys per vehicle. This is why the explanation in the manual is somewhat confusing.

4. After you press the "LOCK" button twice (or whatever it should be - 1 to 4 times), wait five or six seconds, then press the "UNLOCK" button to confirm the program was successful. If it was, the driver door should unlock.

Voila.

Alex:

Thank you - it worked - frightened me a bit as the trunk opened, lights flashed and there was a noticeable thunking under the hood but I can now use both keys.

Can't tell you what the "thunking" noise would be from...

Just joking - but I was seriously going to put it on a Q45 in the mid nineties and would consider it for the A8 if it wasn't for warranty considerations.

The system for the Q45 spec'd out at 450bhp and I had enough trouble with the law even without that.
