Hi, thats what I thought. I know the alarm is separate from the immobiliser and wondered how much gubbins I would need to remotely work central locking and disarm the alarm system. I was pretty sure that the later 156 would have more engine management sensors, as mine has no orange engine light unlike my Wife's SW, it was worth a try. So just to confirm I need,to get a working key with alarm/lock controller which I can then get programmed by Chris? How do I find key guru Chris on this forum? I think I have found his site on fleebay. What would I need to reprogram the key, I have handbooks and radio code but probably no key codes knowing my luck.
