VIDEO: How to Remove a Doorknob with No Visible Screws

Many door handles have visible screws on the trim plate on one side of the door. Simply unscrew these screws, unscrew the latch from the door edge, and remove all the pieces.

If you can't see any screws, don't worry, they're there. But you'll have to take the knob off first.

There should be a small latch near the base of the knob or handle, probably on the exterior side of the door.
Push this latch in, and pull the handle off the door.
Next, find a small slot on the edge of the trim piece. Insert the tip of a screwdriver and pry off the trim piece.

You should now be able to see the exposed screws. Remove the screws, unscrew the latch from the door edge and remove all the pieces.
