Hi all, this is my first post, I hope one of you can help me with my problem.
I just bought an Audi A6 from 1995, with 2 keys, but only one works for the starter, both opens the door (these keys are the old kind, the ones with a small code thing, not the new ones with remote lock builtin, the flip out/in thing, the remote lock and key are seperated).
The one key works fine to start the car, but when I try to start the car with the other key, the engine runs for 2 seconds and then turns off.
I know it´s a security thing, and it can be re-coded, but how can I do this myself?
I´m lost, what do I do?
Hope someone got the answer.
Thank you

 

You're from Denmark, your '95 A6 may have an immobilizer ignition, keys may need to be coded/adapted. Not sure how to do that on '95 A6, call your nearest Audi dealer.

 

Try the following procedure before attempting to go to a dealer.
I bet you bought the car lacking a owner's manual. Good luck.
