I live in a house with two other people and I recently put a locking door knob on my bed room door. Problem is I found out of you push on it a little it will open, the latch that goes into the frame does not stick out far enough due to what seems to be a little wider space between the door and the frame. Any ideas? Its something that I need to remedy fast..since I have have a lot of very expensive items. Thanks!!!!!!!!
