Fixing a door latch that won’t close can often be a straightforward task, requiring only a few basic tools and some patience. The issue might stem from misalignment, a faulty latch mechanism, or obstructions. Here’s a step-by-step guide to help you troubleshoot and resolve the problem.

Why Won’t My Door Latch Close?

A door latch that won’t close can be caused by several factors, including:

• Misalignment: The latch and strike plate may not align properly.
• Obstructions: Dirt or debris in the latch mechanism.
• Faulty Hardware: Worn-out latch or strike plate.
• Warped Door: Changes in humidity or temperature can warp the door.

Identifying the root cause is the first step toward fixing the issue efficiently.

How to Fix a Misaligned Door Latch?

Misalignment is a common reason for door latch failures. Here’s how you can address it:

1. Check the Alignment: Close the door slowly to see if the latch is hitting the strike plate. If it doesn’t align, mark where the latch hits.

2. Adjust the Strike Plate:

   • Loosen the screws of the strike plate.
   • Move the plate slightly up or down to align with the latch.
   • Tighten the screws and test the door.

3. Enlarge the Strike Plate Hole: If minor adjustments don’t work, use a metal file to enlarge the hole slightly.

4. Shim the Hinges: If the door is sagging, adding shims behind the hinges may help realign the latch with the strike plate.

How Do I Clean a Door Latch?

Dirt and debris can cause the latch to stick. Cleaning the latch is a simple process:

• Remove the Latch: Unscrew the latch mechanism from the door.
• Clean the Parts: Use a dry cloth or brush to remove dirt and debris.
• Lubricate the Latch: Apply a light coat of lubricant, such as WD-40, to ensure smooth operation.
• Reinstall the Latch: Screw the latch back into place and test the door.

What If the Door Latch is Faulty?

If the latch mechanism is worn out, replacing it might be the best solution:

1. Purchase a New Latch: Ensure the new latch matches the size and type of the old one.

2. Remove the Old Latch: Unscrew and take out the existing latch.

3. Install the New Latch:

   • Insert the new latch into the door.
   • Secure it with screws.
   • Test the door to ensure it closes properly.

How to Fix a Warped Door?

A warped door can cause misalignment with the latch. Here’s how to tackle this:

• Inspect the Door: Look for signs of warping such as uneven gaps.
• Use a Plane: If the warp is minor, use a hand plane to shave off excess material.
• Rehang the Door: In severe cases, rehanging the door with new hinges might be necessary.
