Re: what year did the keys get the chip/immobiliser
I believe that the immobilizer was new for K5. Am unaware of a source for a new barrel, i.e. you'll have to replace the whole switch if you need one. However if your existing one is OK, a good locksmith should be able to make a new key without changing anything else.
