OUCH...wow that sucks!!! Sorry to hear that.
As far as I know the only thing that will set off the alarm is someone trying to open a door, hood, or trunk when it's locked. Or if someone tries to hotwire it.
Oh yea...also...if the key is in your pocked and you bend over to wipe on some fresh wheel dressing...and you accidentally bump the panic button on the key...but this only happens when you're in the garage with the door closed!
BTW...who did you **** off, and was she worth it?
