How can I bypass the immobiliser on my car?

I have a 1994 Vauxhall Omega which was running fine. When bought it had two keys, one a remote for the other a chipped but non-remote key. The central locking did not work however I removed the door panel as the window regulator packed in and noticed the central locking was unplugged. I plugged it in and although the central locking didn't work off the fob I locked and unlocked the car with the key. I later went to start the car and the immobiliser light came on. I now cannot start the car. Can the immobiliser be bypassed?

Unfortunately, this is a fairly common problem - not just with Omegas but with many cars of this era. One option is to take it to a dealer to get a new key and get the car re-coded, but that is likely to quite expensive. There are some suggestions on Vauxhall forums, but probably the best solution is to take it to an autoelectrician. Try a few numbers and hopefully you'll find one who has encountered this problem (or something similar) before and can definitely fix it.
