Default D2 remote battery replacement

Title says it all - how is this done? My 2nd remote seems to have a flat/dead battery, so I thought I'd ask on here before taking the remote into Stockport Audi.

Flick the key blade out, then look on the back of the key for a small slot. Put a flat bladed screwdriver in the slot and lift the plastic gently while pulling the top part of the key with the blade in it away from the bottom bit with the buttons. It should need very little force.

Once apart, split the 2 halves of the button section with finger pressure, and batteries exposed

Ideally a flat thick blade and just twist in the slot to separate the two halves before splitting the battery compartment.
No need to reprogram anything, just replace the batteries.

Or you can use a plastic spudger if you want to avoid marking the fob.

Usually a single battery in the later D2 fobs I think, a CR2032 (ie 20mm dia, 3.2mm thick).

CR2032 is a very common size that are also used for BIOS memory retention on computer motherboards, so most electronics/computer places stock them.


Kinda ironic Stephen, don't you think, that you own an EV yet it's your petrol-driven vehicle that's had all the battery issues lately

Very ironic - in fact both my ICE cars have had electrical problems, with my Fiat Coupé being the more persistently problematic - they're also both a lot older, which doesn't help. And it looks like the remote issue on the S8 is deeper than just the batteries being flat, as replacing those didn't fix the issue

How far did you get diagnosing it and are all fobs the same (assuming you have more than one)?

You could check that the fobs are transmitting *something* using an RF fob tester. I have a Gunson tester like this that I bought years ago, but this Sealey one is cheaper and looks a better tester.

It may be that your fobs have just been 'forgotten' for some reason; had that happen with mine once or twice.

Have you tried the fob reprogramming ceremony? It goes something like ... leave one key in the ignition then put another key in the door while standing on one leg and pressing unlock.


Failing that, assuming Craig the Keycutter is at the annual meet, you could ask him to program up some nice shiny new ones for you

All good diagnostic tips Mark, and although I don't have an RF test, my main remote works just fine, so there's clearly no problem at the vehicle end. I'll be passing Audi Stockport later, so may just pop in (in my Tesla, always goes down well... ) to see what they think.

If it's only your spare remote that's not working, it may just need to be re-added to the system. Have you at any time used it to lock the car with the engine running (main remote in the ignition)? I think that may be how I accidentally deprogrammed one or two of my spare remotes in the past. Re-adding them by following the usual reprogramming sequence has always worked for me.

Yes, I have! - Sherlock on this thread, not the mint D2 one . So now you know what question's coming next - what's the "usual reprogramming sequence"?
