Programing imobilizer in key
 

-Yes I have done a search in the forums-

I'm trying to figure out how to program the immobilizer chip in my key for my '02 A4
I have tried leaving a key turned in the ignition and then locking the car from outside with the new key but so far that has not worked

Is there another method?
Or what may I be doing wrong?

The dealership has told me that programing the imobilizer is $30
I'd perfer to do it myself

Thanks for the help.

You may have to clear the memory first.



Remote transmitter coding procedure

- Switch ignition on (using separate key).

- Lock vehicle from outside using key to be coded via driver-side door lock.

- Press "unlock" button within 5 seconds often enough to reach next
memory position (in example given, twice). Every time you hit the button
it goes to a different memory position. So if you hit it twice for the first key
and the second key, the first key will no longer work.

- Every press of the button is confirmed by the emergency flashers and
the anti-theft system horn.

- Wait 5 seconds.

- Now press "unlock" button one more time (vehicle unlocks).

- Switch ignition off and remove ignition key.

- Check function of new transmitter.

Notes:
Be sure that new transmitters are always coded into free memory
positions. If occupied positions (distinguishable by a "1") are used,
the transmitter previously coded to this position will no longer work.


Existing remote transmitter recoding procedure

- Press any button on transmitter.

If vehicle does not respond by locking or unlocking:

- Lock and unlock vehicle within 30 seconds using driver-side lock.

- Now check function of recoded remote transmitter.


Clearing memory positions

Notes:
It is possible to clear all memory positions, e.g. if a customer loses
a remote transmitter. Proceed as follows:

- Switch ignition on using key.

- Then mechanically lock central locking from outside vehicle using key.

- Activate remote transmitter "unlock" button on key five times at one
second intervals. A short horn signal will sound each time.

- Then, after 6 seconds, press remote transmitter "unlock" button to
confirm this clearing procedure one more time.

- Central locking should no longer unlock itself via remote transmitter.

- Switch ignition off.

Up to four transmitters can now be coded again.

Thanks for the fast reply-

I think it must be an issue with the remote cuz i'm not getting and feedback from the buttons
i will have to check the batteries

Hey has anyone on the forum thought to make a FAQ section where neebies like me can easily find answers to these types of questions?

I know that lots of questions are asked about things like Keys and Chip-ing
They are asked so much that a search through the forums can take hours and still not find all the posts
just an idea...

thanks again
