How To Reset Volvo guard

I Have a Sep 94 940GLE and i think it is fitted with an optional alarm/immobiliser.It is the one with the blue trim keyfob with one button.I have replaced batteries on this.There is a sensor on the driverside windscreen bar with 2 LEDs and a button. We havent used the keyfob for a year or 2 and yesterday the alarm went off and would not reset when I locked the door..Now alarm goes off everytime I open door and immobiliser locks me out..I really need help quick as I cant use car thank you all in advance

Volvo dealer job I'm afraid. The alarm/immobilser relay has to be removed from car and reset on special piece of kit dealers have. The unit can be disarmed and your remote/s can be re-programmed at the same time. Paul.

Thanks for speedy response. Is there no way of bypassing or deactivating immobiliser for the time being.Cant afford dealership prices at minute but obviously depend on car.I actually dont mind if immobiliser is destroyed in process.Car is getting older everyday and but it is my lifeline.....

Sorry to hear of your problems and I hope they're resolved. Don't suppose you have a spare blue edged single button fob I could buy off you? I only have one for my '95 2.3 LPT and it's on its last legs. Thanks.
