How to Fix a Door That Won’t Latch
With a few basic tools and a bit of patience, you can solve this common door problem yourself, saving you the time and hassle of calling a professional.1. Inspect
Because there are several common reasons for a door not latching properly, the first step is to inspect your door and see if you can locate where the problem is. It may be helpful to check out our Parts of a Door article to familiarize yourself with common door terms. This will give you a better understanding of what you need to do as you follow our repair instructions.2. Gather Tools
The following is a general list of tools and materials that cover everything you need for each step of the door repair process. Chances are, you won’t need all of these materials, but you can continue to reference this list as you try to figure out the issue.- Lipstick (or something to mark your latch bolt)
- Masking tape
- 4-in-1 screwdriver
- 2 ¼ or 3-inch long screws
- Cardboard (or something similar for shimming)
- Curved metal file
- Wood chisel
- Hammer
- Cordless drill (or Dremel)
- Drill bit set (or Dremel carbide cutter)
- Protective eyewear
- Wood filler
- Paint
3. Tighten Hinges
Before you do anything else, you’ll want to check and tighten your hinges. The problem could be as simple as a loose screw causing your door to sag and miss the strike plate hole.4. Shim the Hinges
Due to aging, the hinge mortise (the chiseled-out section that allows the hinge to fit into the door jamb), can sink.5. Sand the Jambs
In an older house, it’s normal for the wood door jambs in the door frame to warp or bulge with age. When this occurs, the issue may not be with the hinges or a misaligned striker plate, it could simply be the door jambs.6. Enlarge the Strike Plate Hole
Before enlarging the strike plate hole, you’ll want to do the lipstick test. This will show you how far off your latch is from the strike plate hole.7. Move the Strike Plate
If all else fails and your door latch is missing the latch hole by quite a bit, the next step is to move the strike plate to match the door latch.If using matchsticks, you may need to file them down so they fit properly, then cut them back so they are flush with the wall surface.
