help1. Understand the Problem

A door that fails to latch usually indicates misalignment between the latch bolt and the strike plate. This can be caused by loose hinge screws, seasonal wood swelling, or a settling house frame. The latch may hit the plate instead of entering the hole, or the bolt may not extend far enough.

Best First Step

Check Hinge Screws

Open the door and inspect all hinge screws. Tighten any loose screws with a screwdriver. If the screw holes are stripped, remove the screw, insert a wooden toothpick or matchstick coated in wood glue, break it off flush, and reinsert the screw.

visibility3. Visual Guidance

See what's happening and how to try the first recovery step.

Mark the Strike Plate MisalignmentClose the door gently and observe where the latch bolt contacts the strike plate. Use a pencil to mark the top and bottom of the bolt's position on the plate.

File or Adjust the Strike Plate HoleRemove the strike plate screws. Use a metal file to enlarge the hole slightly in the direction of the misalignment. Alternatively, you can move the strike plate by drilling new pilot holes.

Deepen the Latch Hole (If Needed)If the bolt doesn't go deep enough, use a 1/2-inch drill bit to deepen the mortise in the door jamb. Be careful not to drill through the jamb.

Reinstall and Test the Strike PlateScrew the strike plate back in place. Close the door and test the latch. It should slide in smoothly without binding. If needed, repeat filing or adjustment.

Replace the Latch AssemblyIf the latch bolt is damaged or doesn't extend fully, replace the entire latch mechanism with a new one of the same size.

Frequently Asked Questions

Why does my door latch work in summer but not winter?expand_more

Wood expands and contracts with humidity. In summer, swelling can misalign the latch. Adjusting the strike plate usually solves this seasonal issue.

Can I fix a door that won't latch without removing the hinges?expand_more

Yes, most latch issues are fixed by adjusting the strike plate. Only remove hinges if the door is sagging significantly.

What if the latch bolt is too short?expand_more

If the bolt doesn't reach the strike plate hole, you may need a longer latch or a wrap-around strike plate that extends the reach.

How do I fix a door that latches but is hard to turn the knob?expand_more

Hard turning usually indicates the latch is binding. Check for paint buildup on the latch or a misaligned strike plate.
