random alarm problems

[:: blade ::]

hi all my alarm on my s3 is playing up, ive had a search but couldnt find anthing basically my alarm doesnt go off if i lock my car while sat in it wait abit and they shake the car from inside, but if me or the other half are driving it will get some beeps from the boot then the alarm will go off for a about 20-30secs then will go off, today its done it 5-6times already and its started to do the other halfs head in as everyone stares at her i had it on vcds a few months back and checked it and the alarm never when it was asked, so presumed the battery had leaked, but the alarm clearly works but when i dont want it to any suggestions?

cheers

The battery in the siren sounds like its on its way, if you do a search on here, its been covered quite a lot.
