I've been struggling with securing my front door for months -- I just can't figure out how to get my door to take a doorknob/lock assembly. Get this: the door has a 1/8 inch deep, 10 inch long section taken out of the side of the door where the face plate would go. Then, within this recessed portion, about an inch and a half from the bottom of the recess, there's a carve out that perfectly fits the face plate. SO, when the assembly is installed so that the face plate sits in its carved out portion, the first 1/8 inch of the latch is actually embedded in the door, and only the rest of the latch fastens.
This solution is less that ideal -- i.e., not very secure. Has anyone ever encountered a door like this? Any help would be greatly appreciated!
