Went into my house and the door was already locked I was in my backyard last night and when I went back inside and turned around to lock the door it had already been locked. This isnt like the lock on a doorknob jiggling closed when the door shut. It is a sliding door and we put a baseball bat down in the tracks and it was already in the tracks once the door was closed. I hadn't stood it up which rules out it falling down or anything, it was placed on the floor in front of it. I'm just glad the door let me back into my house..
