Alarm keeps randomly going off

Alright, time for my newbie question of the month!

 

In the last week or so, my alarm has gone off randomly with no interference from the usual local elements, i.e. bird sh*t, chavs, footballs. One minute I'll be appreciating the wiles of Liz Vicious or Lily Thai and the next minute I have to pack away and rush outside to stop the alarm going off.

 

Then it might go off again 10 minutes later. Sometimes it won't do it for days.

 

Any ideas????

dodgy car battery??

 

had a same thing in past with another car and it was the power fluctuating from the battery, which the alarm thought was someone trying to hotwire it or something.

it stopped when i replaced the battery. :)

What kind of alarm is it mate?

 

As mentioned, it could be the car battery or it might be the back-up battery on the alarm system itself or dodgy siren.

 

Possibly the early symptoms of the following problem..?

Strange. Mine was doing the very same a few weeks ago. I put it down to the carbon bonnet not quite being closed fully and not activating the bonnet closed switch. I made sure the bonnet was latched properly and tightened the bonnet pins a little and it's been fine since.

Hmm, it's a toad alarm. But I'll speak to Matt with the general intention of changing the battery via Halfrauds once pay day has come allong.

 

I suspect it is the battery as when I start the car sometimes, the dials/display/clock dims until the engine kicks into life.

 

But once again, my thanks to you all for your useful suggestions and your variance/speed of reply.
