2. Mechanically lock the vehicle using the Drivers door using a second
key.

will sound once.

4. Wait 6 seconds and press the unlock button once to activate the coding
procedure. The remote control will now be programmed.

NOTE : When performing programming on additional remotes the procedure
is the same, except you press the unlock button 2, 3 or 4 times for the

P.S I HAVE TRIED THIS AND IT DID NOT WORK FOR ME AND THIS GUIDE WAS BOUGHT FROM EBAY BUT YOU NEVER KNOW IT MIGHT WORK FOR 1 OF YOU GUYS!
THIS GUIDE IS NORMALLY USED IF YOU HAVE PURCHASED A KEY FROM EBAY OR ELSEWHERE OR EVEN SO IF YOU REPLACED BATTERY AND THE FOB HAS STOPPED WORKING!
THE PART NO OF THE NEW KEY SHOULD BE THE SAME AS YOUR ORIGINAL KEY, THE NO CAN BE FOUND BY SPLITTING THE KEY IN HALF WITH A BIT OF BRUTE FORCE OR USE SOMETHING LIKE A KNIFE TO SPLIT IT CAREFULLY!
GOOD LUCK GUYS HOPE IT WORKS FOR YOU

good advise tabby666. This will only program the remote central locking, not the immobiliser. To program the immobiliser you need specialist diagnostic equipment, and the 5 digit pin code, but might be useful for people who have ordered a new remote to replace a broken one.

Hi I'm new to the site, sorry to go slighty away from your topic, but it might help someone.
You are correct about the sync of the radio part of the fob, newer Audi vehicles just need the key in the ignition ( the dash insert has the type 3 or newer type 4 immob built in and reads the transponder chip in the key and knows its the correct key for the car. It then sends a signal via the CAN network to allow the learning function to sync the radio fob on the key) push lock and unlock on the remote, turn ignition off, close door and press lock unlock.

Some A4 cars have faulty key fobs and affected fobs are being replaced by the factory.
If you find your A4 05 or 56 plate wont allow opening via remote, use the key in the drivers manual lock (isnt one on the passenger side). Unlocking will require more force than you think, once open you must quickly turn the ignition on to disarm the alarm and unlock the rest of the car, sometimes carrying out the above procedure will work to re synchronise the radio side of the fob.

When we recode the transponder part of the key fob, we used to fax the importer with the AUZ5Z.......... and the chassis number, they would give us a seven digit pin number to allow login to dash to allow the key code proceedure.
Now the only way we can code keys is via an online link to the factory. We dont see any codes. The dash communicates with the database and along with certain security steps, the keys can be coded.
Takes all the fun out of it, but also increases security I suppose.
The radio code is via the online function also.

Most manufacturers of high end cars use the key to set various heat,seat,mirror,radio etc settings to the last position used when a particular key was used.

Another tip if you are replacing a broken key fob which is correctly coded to the immobiliser.
If just the radio side of the fob goes down, for Audi Vw vehicles you can buy either the radio fob, just the key inc transponder or both.
You will need the V5 and two forms of id to buy the key part. This will then need coding along with all the other keys you have.

If you are careful, you can dismantle the damaged key part by removing a small phillips screw under the manufacturers badge, very gently take the two sides apart and remove the glass transponder. It is glued in but gentle picking at the glue will allow removal. Fit this in the new key and reassemble. You wont need to have all your keys programmed.
Refitting the spring is difficult at first but dead easy when you get the idea how it works.

Firstly I would like to say Hi, and how good it is to see a VAG tech here.

Secondly I would like to say some good points made there.

I dont know how long you have been a vag tech but do you remember the old 5 digit codes (generally 4 digits preceded with a 0)? VAG abolished the 5 digit code in favour of the "more secure" 7 digit code which also needed the date that the code was generated, workshop number and importer number...

Well all that happens with the 7 digit code is it is converted back to a 5 digit code within the equipment that is coding the keys. With the correct equipment and knowledge (that I have) it is possible to "read" the 5 digit pin code from the ECU (on immo 3 & 4 equiped vehicles), the dash (on immo 2, 3 & 4 equiped vehicles) or the immo box (on immo 1 equiped vehicles). Also I am buying my keys from VW china who supply me at less than half the UK price and dont need to see a V5 and driving liscence. It is crazy that my local VW and Audi parts man cannot supply me keys now when they have been doing so for years! Once upon a time I could go to my local dealer and buy a key blank and plip, then wander over to the service dept who would GIVE me the 5 (or later 7) digit pin code then go away and cut and code the key myself. I agree that most of these changes have occured because of security issues but why cant VAG accept proof of credentials as a bona fide vehicle locksmith to supply me keys. I think a small ammount of it is to make it more difficult for people like me to stay in business serving customers at £38 per hour when they want the full £102 per hour.

If it can be made by a man it can be broken by a man. It does my head in the ammount of time I have to spend taking apart and studying ECU's, dashes, keys, immo boxes, BSI's, BCU's, UCH's etc etc keeping up with the changes that car manufacturers make just in order to continue trading!

Hi, yes I hear what your saying.
I do remember the 4/5 digit code, hey they even used to supply that number on a key tag, how easy was it then?..
The reason I think they have gone to the FAZIT database in Germany is due to pressure to secure the cars even more with pressure from Thatcham security and the people who really matter the punters. Hey 2005> new A3 A6 A8 cars can no longer be broken into when customers lock the key in the car, (you may be able to) we have to get the correct key OR cut one to key number. It was possible to carry out certain lockout proceedures, these have now been blocked.
Its great you are able to offer the service you do, just imagine what will happen in ten years time when a £60,000 A8 is worth £4500. Without people like you striving to keep up, they would be even more worthless.
I don't think its deliberate, its just progress. I will send you another SSP which will open your eyes as to where its heading.

Hi delambo, was searching for some info on remote programming on an A4 and look who's name pops up, lol Super Mod too, show off!

It's not that I am stalking you or anything.

I have just bought a 2007 SEAT Toledo, and like most people find that an additional remote control priced at around £120 is excessive.
I have bought a NEW GENUINE 3 button remote from ebay.
my local high street locksmith has cut the key, and using the instructions supplied in the vehicle handbook, I have synchronised the remote, so that all the buttons work correctly.
However when I use this key to turn on the ignition the vehicle goes into SAFE mode and will not start. (immobilised??). As I understand the situation the key now needs to be linked to the vehicle using the seven digit code supplied with the original keys.
Question.. From the comments on this thread it would seem that this needs to be done by a dealer using vag.com. Is this correct or is there any other way?
I also believe it is possible to buy vag.com leads,etc on ebay... is this a viable way to do it.. or something to be avoided at all costs
