We've got a 06 Ford Fiesta Ghia. For some considerable time now the alarm has been randomly activating for no reason and the situation is now highly embarrassing.

On the advice of local professionals we have tried a number of remedies - all without success. We have secured the car by locking it manually rather than using the electronic system. We have been careful to ensure that the doors are closed firmly and the windows closed. The locking system has been inspected by a professional mechanic and no obvious fault has been found.

Anyone got any (sensible) ideas please?

In reply to FesteringSore: dodgy door lock? Thinks it's open when it isn't .

I wouldn't know if you;d see this as sensible, but how would you feel about disabling it and leaving the 'alarmed' stickers in? It depends how well to do you are I guess, whether you want to risk it, but I'm thinking an 06 Ghia wouldn't be as desirable as more modern cars would be to thieves.

For when all else fails...

I would think the random nature would discount that. Maybe

Our (professional mechanic) neighbour was going to do that but then found out that disabling the system had the effect of a far more drastic disablement(I think that's what he meant) and would also invalidate the insurance

Are you saying sticky door lock as in needs oiling?

In reply to FesteringSore:
Maybe . If I trusted the remote locking sometimes a door seemed not to lock properly, and at some point would think it was not locked, turn on the interior lights and so on. In your case the now open lock might make the car think a villain is doing bad things and off you go.

Don't know if/how you'd diagnose that

You wouldn't need to disable it if it was silent though, would you? Does it honk the horn or have it's own sounder - if the latter, leave the system as a whole alone and just nobble the bit that makes the noise!

I'm thinking that a car forum could possibly helpful?

I had a similar problem with my van and the culprit turned out to be a slightly worn plastic grommet that pressed on the door light switch so that when the door rattled from wind or a passing car it activated the alarm. Diagnosis involved setting the alarm and waggling the doors. My neighbour had a similar problem and it turned out to be a spider hiding behind the rear view mirror.

My previous car would set the alarm off if you left a phone in it, but only hours later - usually in the middle of the night.
As Timmd suggested, how about an appropriate forum for your car? I generally find that whatever is wrong with my car, it's a known fault and someone has posted a step by step guide with photos. I bet if you search for how to disable the alarm, someone will have done it before and written a guide. As for the insurance company, how would they ever find out?

Call into your local ford dealership and ask them how to disable. I had a similar problem with a slightly older Mondeo, phoned in from work where the alarm had gone nuts and they talked me through which wires to cut.

Pay an auto electrician to disable the alarm. Almost certainly cheaper than paying them to do an open ended fault finding exercise.

I once had a Ford Escort that developed a problem with the alarm and did exactly as you say - kept going off at random, usually at night, sometimes several times.

Got to the point I'd just park it unlocked in the garage, but it became a problem when I was working away from home and couldn't do that.

In the meantime, various investigations had checked all sorts of things for bad earths, dodgy contacts and ruled out only happening when it was wet, I'd replaced the bonnet sensor, as that was a known culprit for the symptoms (was totally knackered, but made no difference), and didn't get to any solution.

In the end, I managed to just about reach between the bodywork and a trim panel in the boot and pull the wire off the alarm horn hidden in the rear panel - end of problem

If only we could find a climbing auto electrician. .......

(based near Abergavenny if that's any help?)
