Guys,

I am trying to add a new key to the car. Getting several ways to do so and can't get any of them to work. Does anyone know what to do?

Here is what I found so far

Audi-Resource - Key Fob Matching

Ross-Tech: VAG-COM: Remote Control Matching Info

DIY: How to program your Audi flip key fob.

Ok, so I went to the dealer today
They said they could not program this key because it is not an A8 key, is there any difference? This picture is P/N 8E0837220L

Only a dealer can do that for you.

I've researched this matter almost to exhaustion.

For the A8 4E 2003-2009, Q7 and A6 4F at least, you need either to go to the dealer, he connects the car to the VAS Computer, and with that to the factory server, and updates they new key to the car.

They will charge anything from zero to 100€, depending on if you need something else done with the Computer at the same time.

It IS possible to do this offline too, with a tool called "abrites", but that costs like 1500€+++ depending on software etc.

This key matching is NOT possible to do with VCDS or any rosstech software on our cars!

Not sure if this will work but while looking on YouTube I ran across this. The main thing is that you will need is the pin number.

I hope this will help.

Yes, as noted only dealer can program keys for all practical purposes. But, maybe everybody else missed it, but that picture is not a D3 key. D3 keys are basically symmetrical in all dimensions. The one in your picture has one side that is curved inward. I don't know all the variants, but that strikes me as maybe a Q7 or C6 A6 type key. Gotta get at least the right electronics fob to even start to play here.

it is a B7 A4 key, may also be used on the Q7 and A6.

I know the B6 guys can "upgrade" to this B7 key because the modulus are the same between the B6 and B7. Though the dealer will never help you with this issue.


In an A8 i don't think you would ever be able to change key fob unless you deactivated the immobilizer somehow and loose the push start.

Later B platforms can cross at A5/A5 and Q5, but seems like a way bigger platform leap over to the C's and the Q7. C6 and Q7 are electrically/electronically similar to D3 in a variety of ways, but B stuff is pretty different world to me, both from my C5 and D3 experience, and my newer Q5 (a la B8) experience.

When I dealt with even year 2000 pre-immobilizer keys on my C5 A6, they were also still very finnicky at the exact part number level, even if the fob looked the same otherwise. FWIW, you can mail order both the fob and the cut key from a mail order dealer if you send in your registration with your name on it. Or buy a known good looking D3 fob from EBay and then just order the cut key component from the dealer. You still have to pay for programming, but it cuts the cost down. Dealers charge me the same regardless of how many keys, so when I do it (typically near new), I have them do a couple at same time.

I don't know why you like that type of key. A8 key is functional.
