Just wanted to add a post to this (even though it's an old thread) given my experience last night.
Car is parked up in the garage all locked up after a day out, went to bed, fast asleep and the alarm sounds off around 1AM. Certainly woke up pretty fast, checked the garage and car - all was fine, nothing had hit the car from falling down from the garage walls/ceiling and all the windows/doors etc... were fine (and no single horn beep when I originally locked).
So locked up again and re-set the alarm, back to bed and 0230 the alarm goes off again. So same process but this time decided to check everything out inside the car, couldn't find anything and just as I was getting out a moth crawled out from near the air vent area at the front of the car (near where the windscreen meets dash)! It must have been big enough to trip the interior sensor whenever it decided to go flying around. I think it got in when I had had the roof down earlier in the day. Since the removal of the moth all is well again.
