I figured that was the way they got in but upon inspection of the windows, I couldn't pry them back despite them being frameless. Now, with a tool of some sort I'm sure it's easy. The unlock button faces directly up on the arm rest, so if you could get a rod in there it would be a snap to unlock. But I didn't see any scratches or marring on the plastic or windows. I too would love to know how they are getting in. Then maybe I could do SOMETHING. I'm actually going to unplug the armrest lock switch... thanks for making me think of that.
