197: Help...bloody alarm keeps going off

The bloody alarm has started going off when I open the car boot or door. It also sometimes goes off not wnen I open the door but when I get in...It can go all day without doing it then it can keep doing it. Theres no pattern!!!

Its driving me crazy......
 
Does the alarm go off, or just beep a few times? It could be a spider! Lol!
 
Have you changed the bonnet? The catch under the bonnet is very temperamental a bit of blue tack did the trick when I had a carbon bonnet on
