Car alarm constantly going off

[tuesdayschild1]

Not AIBU, but I need ideas fast before we all lose the plot.

Our bloody car alarm keeps going off every night. Multiple times. Driving us, and no doubt the neighbours, insane. It goes off for 30 seconds or so, then stops. Then 20-30 mins later it will go off again, for 30 seconds. Repeat all night. By the time we get out to the car (or window) the alarm has stopped.

The car has been to the garage and they can't find any faults with it. We have tried parking it in different parts of the drive way; close to the house, in front of the garage, at the end of the drive, wherever it's parked the sodding alarm goes off .

We think it's possibly a cat, as it only ever happens at night. How on earth do we stop it if it is a cat? Anyone have any advice, short of selling the bloody thing!!

Ours used to do that and eventually we discovered it was a battery fault! It happened the first week we moved in to our new house! Mortifying way to meet the neighbours!

Oh really? How did you discover it was a problem with the battery?

Had the same issue, turned out I had a teeny spider, living behind one of the sensors.

Ours has just started doing this - it’s not a 2009 Ford Fiesta is it?!

I think ours is because the sensor in the boot is failing or loose or something, because I’ve also noticed I keep getting a ‘boot open’ notice on the dash.

I have to admit, mine has been left unlocked with the wings tucked in since last week.

Is there no way to lock the car without alarming it?

If I leave my iPhone in my OHs car it seems to set the alarm off (vibration possibly?) but presume that’s not the case here.

Mine does this. Lock the car manually and it doesn't set the alarm.

When I had a previous car, it went off when I was driving home from work so I pulled into an asda and called recovery firm. It turned out to be a dodgy connector on the bonnet. The security guards came over to me thinking I was trying to steal it. Removing the fuse shut it up until it was fixed.

Rahul and Toomuch - locked it using the key last night and success! Thank you

Thanks everyone - still no idea what's causing it, perhaps we'll take it to another garage to be checked out.

Sorry Eliza forgot to add it's not a Ford x
