Help alarmmm!!

hey guys my car alarm keeps fkn going off for no fkn reason! i lock the car it makes 1 beep noise if a door or boot or bonnet is opened it beeps 3 times, so my problem is i lock my car and it beeps 3 times i've checked everything if it's opened or not and it still beeps 3 times, and just tonight i've locked the car and it beeped once, kinda wrapped then fkn out of no where the alarm goes off for no reason and i've been standing next to my car, previously i know the alarm sensitivity is very strong so to make the car alarm go off the car would have to be literally kicked in. now i cant find anything on ozhonda on "car alarms going off" so if anyone's who has had this problem before and fixed it please help me!!

What alarm is it?

A door sensor might be faulty, thinking the door is opened after arming causing it to go on disco mode.

Next time it goes off, look inside the dash and see if the door ajar idiot light is on or flickering.

yeah i'll give that a go tomorrow it's too dark to work on atm but i just need ideas now so i know what i'll be looking for tomorrow thanks flipfire... anyone anymore help!!!
