Hi folks, I know that there are a million topics on this issue but I just can't find an answer that helps me.
The girlfriend has just bought a 2004 A3 and we received two keys with it. Unfortunately one of the keys doesn't unlock the doors via the buttons and as well as change the battery I've tried every method I could find to resync it.
I finally gave up, thinking the key was broken, and bought a new key (same part no) from a certain auction site. The new key arrived but I cannot sync this either. I'd say I'm technically minded so this is starting to annoy me.
Does anyone have any idea what I am doing wrong? I have VCDS if that can help.
Thanks for your time
