  1. The first step is the lipstick test. It is done to check whether the latch and the door plate are misaligned or not. So smear lipstick on the door and some masking tape on the strike plate on the door. Now close the door to see where the latch is contacting the strike plate.
  2. After finding out the points where the latch is contacting the strike plate if these points are too high or low try to tighten all the door’s hinge screws. If this doesn’t resolve the problem, remove one of the screws on the jamb side of the hinge and a drive 3-inch screw in it. The long screw will draw the door jamb in slightly and will grab the door frame. Do this on the top hinge to raise the latch on the bottom one for lowering it.
  3. If the long screws don’t solve the problem, measure the misalignment of the latch to the hole of the strike plate. If the difference is 1/8 inch or less remove the strike plate and enlarge its hole using a file.
  4. If the latch is missing the strike plate by a difference of more than 1/8 inch high or low or it is contacting the strike plate at the correct level but doesn’t go far enough to lock up, then the strike may have to get reposition moving it up or down and in or out. Use a sharp chisel to enlarge the hole of the strike plate mortise. Hold the strike plate in the plate and drill 1/6 in new holes for the screws. Now install the strike plate back and fill the gap in the mortise with wood filler. Paint or finish the patch after removing the strike plate and replace it again for the door to look as perfect as it was before.
