Programming Keys

[james_suckling]

Having bought a new key, and swapped the blade over (just for asthetics as the old key looked at bit worn), I've managed to completly ****** up the coding on all my keys now!

I've put the blade back in the original key now (because although I could get the new key to unlock the car, it wouldn't start it), but now I cant seem to have more than one key working the central locking remotely.

If I put the spare key in, and program the original key in the door, I can get it to work. If I try and program the spare key, this then works, but the other doesn't.

What am I doing wrong!!!???? I just seem to be swapping the coding from one key to the next, instead of programming them both!

how are you trying to code them, via a key in ignition and one in the door?

Thanks for that Khufu.

I was trying the one key in the ignition, and one in the door method, but could only ever code one of the keys. I now know why!!

Will try that in the morning...

 

[james_suckling]

Sorted!!

Thanks Khufu

sweet, that was straight out of autodata - couldn't cut n paste. Expected somebody to have answered it by the time i'd typed it all out LOL.

This is good info khufu, maybe this one should be sticky mods?

 

[bainsyboy]

I agree regarding being a sticky. I take it that this is the same procedure for all audis?

hi
i have a 52 reg a3 and only have 1 key. a friend of mine had one from his 51 reg a3 which he gave me . the numbers on the keys are the same 4do so the remote can be programed . i take it i just need to get a blade cut , but do you have to go to a stealer to get the chip inside the fob programed or is there anyone in the newcastle area that does it. cheers

Yes you can use this key. As described above, you can program the remote alarm/locking part of the fob yourself. Indeed you do have to visit the dealer to have the immobiliser part adapted.

You can do the immobiliser part yourself if your car was built before march 2002, you have the four digit code from the "scratch off" panel on the plastic service key tag and yopu have access to VAG-COM.

cheers , i dont have the plastic service key so it looks like i have to go to my dealer and get robbed blind

Both my keys are fob keys, does this matter when trying to reprogramm?

No it doesn't.
