You bought a new doorknob or deadbolt and discovered the latch hole in the door edge is in the wrong position. The new latch won’t fit because the old hole is at a different backset measurement, or the hole was drilled too high, too low, or at the wrong angle. A misdrilled latch hole is a common DIY mistake in West Town, Chicago, and it requires either filling the old hole and drilling a new one, or using an adapter plate.
Door latch holes come in standard backset measurements (2-3/8 inch and 2-3/4 inch from the door edge to the center of the bore hole). When a previous lock was installed at a different backset, or when a DIYer drilled the hole incorrectly, the new latch won’t align. Fixing a misdrilled latch hole requires careful measurement and either redrilling or using an adapter.

Quick Answer: How Do You Fix a Misdrilled Latch Hole?
If the hole is at the wrong backset, fill the old hole with wood filler or a wood plug, let it dry, and drill a new hole at the correct position. Use a template from the new lockset to ensure accurate placement. If the hole is too large or misshapen, use a filler plate or bore hole reducer. For minor misalignment, some latch mechanisms have adjustable faces that can accommodate slight position differences.
Why Latch Holes Get Misdrilled
Several factors can cause a latch hole to be drilled incorrectly:
Wrong backset measurement. The most common cause. Door locks come in two standard backset measurements: 2-3/8 inch and 2-3/4 inch from the door edge to the center of the bore hole. If the previous lock was at a different backset, the old hole won’t align with the new lock.
Improper drilling technique. DIYers who drill their own latch holes sometimes drill at the wrong height, wrong angle, or wrong size. Without a proper template or jig, accurate drilling is difficult.
Using the wrong drill bit. The latch hole requires a specific size drill bit (typically 1-1/4 inch for the edge hole). Using the wrong size creates a hole that doesn’t fit the latch properly.
Not using a template. Most locksets come with a paper template for accurate hole placement. Skipping the template and estimating by eye often results in misaligned holes.
Drilling through without a stop. When drilling the edge hole, drilling all the way through the door creates a larger exit hole and can damage the door. A drill stop or backing board prevents this.
Multiple hardware changes. When a door has had multiple lock changes over the years, each at different backsets, there may be multiple old holes that need to be filled.
Can You Fix a Misdrilled Latch Hole Yourself?
Yes, with careful measurement and the right tools:
Fill the old hole. Use wood filler, epoxy-wood flour mixture, or a wood plug to fill the old hole. Let the filler dry completely.
Mark the new position. Use the template from the new lockset to mark the correct position for the new hole. Measure the backset carefully (2-3/8 or 2-3/4 inch from the door edge to the center of the bore hole).
Drill the new hole. Use the correct size drill bit (typically 1-1/4 inch) and drill at the marked position. Use a backing board to prevent blowout on the exit side. Drill slowly and straight.
Chisel the mortise. Use a chisel to create a flat mortise (rectangular recess) for the latch faceplate. The mortise should be the same size as the faceplate and deep enough for it to sit flush.
Install the new latch. Insert the new latch mechanism into the new mortise and secure with the faceplate screws.
Tools and Materials Needed
- Drill and drill bits. 1-1/4 inch bit for the edge hole, 2-1/8 inch bit if the bore hole also needs redrilling.
- Wood filler or epoxy. For filling the old hole.
- Hammer and chisel. For cutting the new mortise.
- Tape measure. For measuring the backset accurately.
- Pencil. For marking the new hole position.
- Lockset template. For accurate hole placement.
- Backing board. To prevent blowout when drilling through the door edge.
- Sandpaper. For smoothing the filled area.
Step-by-Step: Fixing a Misdrilled Latch Hole
Step 1: Measure the backset. Measure from the door edge to the center of the bore hole. Determine if the correct backset is 2-3/8 or 2-3/4 inch for your new lockset.
Step 2: Fill the old hole. Use wood filler or epoxy to fill the old latch hole. Overfill slightly to allow for sanding. Let the filler dry completely.
Step 3: Mark the new position. Use the lockset template to mark the correct position for the new hole. Align the template with the bore hole and mark the edge hole position.
Step 4: Drill the new hole. Use the correct size drill bit and drill at the marked position. Place a backing board against the exit side to prevent blowout. Drill slowly and straight.
Step 5: Chisel the mortise. Use a chisel to create a flat mortise for the latch faceplate. The mortise should be the same size as the faceplate and deep enough for it to sit flush with the door edge.
Step 6: Sand the filled area. Sand the filled old hole smooth. Prime and paint to match the door if needed.
Step 7: Install the new latch. Insert the new latch mechanism into the new mortise and secure with the faceplate screws. Install the doorknob and test.
