The pocket press is a valid explanation, but it has yet to happen to me. I'm a big guy w/ a lot of stuff in my pockets as well. so you would think it would be a regular thing, but it's just not the case.
My key has unlatched inside my pocket before but I've yet to experince trunk openings or alarms.
