Dead Bolt

Malachi has figured out how to open the dead bolt. He gets a stool and puts it by the door and opens it. I had to hide all the stools and anything little he can move close to the door. I do have a child safety door knob cover over the handle so he can't open it though. By the way that lamp isn't plugged in...he broke it a while back and I just haven't gotten rid of it yet.
