OK! First things first. Who fitted it? If it was fitted by a qualified installer, go back to the shop it was fitted and get them to look at it. If you did it yourself, I think you may have made an error in your connections. I installed an alarm in the in-laws car and they had the same problem. After some investigation and research, Google is your friend, I found that the immobiliser relay was not connected properly. This may be your problem.

But first, I would suggest you take it back to the shop where it was fitted, if that is the case.

Good luck!

I had a similiar problem. It was just the siren that was gone. Some of the tracks on the circuit board had gone and were making contact with other tracks. So it kept coming on when I was driving.

If it is as simple as the siren being f&*ked, you can simply head off to jaycar and buy one of their universal sirens. Connect it up via the siren signal wire and bob's your uncle.

If you don't know how/what you're doing, it may be a better idea to head off to a sparky and sort it that way.
