Hi,

The alarm on my v6 vectra keeps going off for no reason after i lock it with the key-fob

Its just started happening over the past two weeks and now im not able to leave the car locked at all!!!

Any ideas? - ive tried pressing the alarm button on the dash before locking the car but it makes no difference

Cheers

dodgy electical connection making voltage drops. If the button on the dash doesn't stop it then it's not a prob with the interior sensors. I'd go with a dodgy connection on a system which has a permanent live like interior lights.

Cheers for that, - do you know if there are any alarm wires running upto the stereo as ive fitted a new head unit recently and wonder if this is causing a problem

Could be the permanent live wire to this stereo that's loose.

The usual culprit is the bonnet pin switch not being in correct alignment.

i would check behind the stereo could be loose connection if problem started when you fitted stereo if not its then a case of following the lives from the alarm m8
