I bought the car with 1 key, lost it and had new keys made and programmed. Since then I have now found the original key (which no longer works). Is there a way I can reprogram this key back in without VCDS or is it a case of taking it to the local garage? I had a reasonable quote and it's booked in for MOT at an independent this month.

 

I tried the guides on youtube which show how to do it but unfortunately this didn't work for me

 

Note: I own 3 remote keys and 1 standard

 

Any help appreciated

I don't think VCDC will do it. Vag Tacho will, but I think that still only works on Windows XP.

Well when I was talking to the garage they originally said they couldn't do it and would have to send me to a specialist or something, but since I have the immobiliser code written down that they should be able to reprogram the key for me and just charge labour. Not sure how they'd do it however

I've only ever done it with Vag Tacho. The garage might have something similar.

You can do it with VCDS if you have the four digit pin.

Either that or most places that cut keys can clone it off one of the others.
