Fix a door that will not latch
We'll diagnose why the latch does not engage—strike plate misalignment, bent latch, hinge sag, or warped frame—and fix it or tell you when to call a pro.
What you'll need
- Screwdriver (Phillips and flathead)
- Pencil (to mark latch position)
- Thin cardboard or wood shims (if hinges need adjustment)
- File or chisel (if strike plate hole needs enlargement)
Step-by-step diagnostic

- Follow this guide Work through the full procedure from confirming the symptom to testing the fix.
- Strike plate misaligned The latch hits the strike plate but does not enter the hole.
- Latch or hinges The latch does not reach the strike plate, or you suspect a bent latch or hinge sag.
- When to call a pro The frame is warped, the door is heavy commercial-grade, or fixes did not work.

Steps
Goal: Confirm the symptom, then isolate strike plate misalignment, bent latch, hinge sag, or warped frame.
- Close the door and push firmly. Note whether the latch clicks into the strike plate.
- Symptom confirmed: The latch does not engage—proceed to Check the strike plate.
- No problem: The latch engages and the door stays closed—no action needed.
Check the strike plate
Goal: Determine if the strike plate is misaligned with the latch. If yes, adjust it.
- Look at the strike plate hole and the latch position when the door is closed. The latch should enter the strike plate hole cleanly. If the strike plate is too high, low, or recessed, the latch will not engage.
- Mark the latch position on the frame with a pencil to compare. You should see either alignment or a visible offset.
- Misaligned: Proceed to Strike plate path.
- Aligned: The latch or hinges may be the cause—see Latch and hinges.
Strike plate path
Goal: Fix a door that will not latch because the strike plate is misaligned.
- Loosen the strike plate screws (do not remove). Move the strike plate so the latch enters the hole. If the hole is too small or in the wrong place, enlarge it with a file or chisel.
- Tighten the screws. Close the door and push firmly.
- Symptom confirmed: The latch still does not engage—see Latch and hinges.
- No problem: The latch clicks into the strike plate—done.
Latch and hinges
Goal: Fix a door that will not latch because the latch is bent or the hinges are loose—inspect, replace, or shim.
- Open the door and inspect the latch. A bent or worn latch may not extend far enough. Replace it if damaged.
- Lift the door by the handle. If it moves up and down, the hinges are loose. Tighten all hinge screws. If the door sags or is misaligned, shim the hinge.
- Symptom confirmed: Still will not latch—see When to get help.
- No problem: The latch engages after replacing or adjusting—done.
When to get help
Call a carpenter or handyman if:
- The door binds or sticks when closing (different problem—door binding, not latch alignment).
- The door frame is warped.
- The door is heavy commercial-grade or fire-rated.
- You have tried adjusting the strike plate, replacing the latch, and tightening or shimming hinges and it still will not latch.
Do not force a door that binds—it can damage the frame or hinges.
Verification
- The latch clicks into the strike plate when you close the door.
- The door stays closed without pushing or holding it.
- Hinge screws are tight and the door does not shift when you lift it.
- The latch extends and retracts smoothly when you operate the handle.
Escalation ladder
Work from the device outward. Stop when the problem is fixed.
- Confirm symptom Note whether the latch engages the strike plate when you push the door closed.
- Strike plate alignment Adjust the strike plate so the latch enters the hole.
- Latch — inspect and replace Check for bent or worn latch; replace if damaged.
- Hinges — tighten and shim Tighten loose hinge screws; shim hinges if the door is misaligned.
- Call a pro Warped frame, heavy commercial door, or repeated failures—call a carpenter or handyman.
What to capture if you need help
Before calling support or posting for help, have these ready. It speeds everything up.
- Whether the latch hits the strike plate or does not reach it
- Strike plate alignment (latch position vs hole)
- Whether the latch extends and retracts smoothly
- Whether hinges are loose or the door sags
- Steps already tried
Does the door close but the latch does not engage?
Close the door and push firmly. If the latch does not click into the strike plate, the door will not latch.
You can change your answer later.
No action needed
Is the strike plate misaligned with the latch?
Look at the strike plate hole and the latch position. The latch should enter the hole cleanly. If the strike plate is too high, low, or recessed, the latch will not engage.
You can change your answer later.
Adjust the strike plate and test
You can change your answer later.
Is the latch bent or worn?
Open the door and inspect the latch. A bent or worn latch may not extend far enough to engage the strike plate.
You can change your answer later.
Replace the latch and test
Are the hinges loose or is the door sagging?
Lift the door by the handle. If it moves up and down, hinges are loose. A sagging door may not align the latch with the strike plate.
You can change your answer later.
Tighten hinges and shim if needed
