I recently purchased a 2005A3 but onlygot one key. I have bought areplacement key and got a blade cut. Iwant toprogram the remote so that it can open the doors / switch off the alarm. (I realise thatI will need to get itcoded to the immobiliser todrive the car)

I have followed the instructions below which a member of the forum kindly gave me butthe car doesnt respond!

Icurrently only have one fully functional remote andan identical one which Iam trying to program.


Any help appreciated

------------------------------------
Instructions I have followed

1.Take a spare key and insert it into the ignition. Turn it one click forward.

2. Roll down your window just in case. Step outside the car, and lock the car with a second key.

3. With your second key fob press the unlock button. The lights should flash.

4. Now lock the car with the key fob, and then unlock it.

5. Remove the key from the lock and the key from the ignition, and try it's function

 

I don't know about the instructions you posted, but I was able to make changes like those you want using the VAG-COM interface cable and software sold by Ross-Tech.
