Locate the screws on the flange on the inside of the door. Remove the long screws that hold the latch together with a Phillips screwdriver.
Pull the latch pieces on the inner and outer sides of the door to remove them. You may need to slide the blade of a butter knife between the flanges and door panels to loosen them. Because the latch components fit snugly together, you may have to jiggle them to separate them.
Unscrew the plate on the edge of the door with a flathead screwdriver. Remove the plate. Pull the bolt portion of the latch through the hole in the edge of the door.
