It’s an everyday occurrence; you’re simply trying to leave your house, but the door just refuses to latch. Sometimes it’s just a tiny misalignment. Other times, there could be a bigger underlying issue at hand. No matter the reason, a door that won’t latch is a major inconvenience and can even be a security hazard. But don’t worry, in this article, we’ll provide you with a step-by-step guide on how to fix a door that won’t latch, saving you time and money while ensuring that your home is safe and secure.
Before you start any repairs, it’s important to first determine the cause of the latching problem. One common issue is a misaligned strike plate. This is the metal plate that the latch bolts into when the door is closed. If the strike plate is not properly aligned, the latch may not be able to fully engage, preventing the door from latching securely. Another potential cause is a worn or damaged latch bolt. The latch bolt is the part of the latch that actually extends into the strike plate. If the latch bolt is worn or damaged, it may not be able to fully engage with the strike plate, again preventing the door from latching.
Once you’ve determined the cause of the latching problem, you can begin repairs. If the strike plate is misaligned, simply loosen the screws that hold it in place and adjust its position until the latch bolts into the strike plate smoothly. If the latch bolt is worn or damaged, you will need to replace it. To do this, remove the screws that hold the latch bolt in place and pull it out. Then, insert the new latch bolt and secure it with the screws. Finally, test the door to make sure it latches properly.
Diagnosing the Problem
When a door won’t latch, it can be a frustrating experience. The first step in fixing the problem is to diagnose the cause. There are several potential issues that could be preventing the door from latching properly.
Strike plate alignment is a common cause of latching problems. The strike plate is the metal plate that is attached to the door frame and that the latch catches on when the door is closed. If the strike plate is not aligned properly, the latch will not be able to engage with it, and the door will not latch securely.
Damaged or worn components is another potential problem. The latch, the strike plate, or the door itself can become damaged or worn over time, which can prevent the door from latching properly. If the components are damaged, they will need to be replaced in order to fix the problem.
Door sag is a condition in which the door has dropped from its original position, causing the latch to no longer align with the strike plate. This can be caused by a loose door hinge, a warped door frame, or a foundation problem. Door sag can be fixed by adjusting the door hinges, replacing the door frame, or addressing the foundation problem.
In the vast majority of cases, door latching problems can be diagnosed and fixed relatively easily. By following the steps outlined in this article, you should be able to get your door latching properly again in no time.
Adjusting the Strike Plate
The strike plate is the metal plate on the door frame that the latch bolts into when the door is closed. Over time, the strike plate can become misaligned or damaged, which can prevent the door from latching properly. To adjust the strike plate:
- Locate the strike plate on the door frame.
- Check to see if the strike plate is loose. If it is, tighten the screws that hold it in place.
- If the strike plate is not loose, you may need to adjust its position. To do this, loosen the screws that hold the strike plate in place and move it up, down, left, or right until the latch bolts line up with the holes in the strike plate.
- Once the strike plate is in the correct position, tighten the screws that hold it in place.
If you are having trouble adjusting the strike plate, you can call a locksmith for assistance.

Adjusting the Door Hinge
Inspecting the Hinge Screws
Inspect the screws on the door hinges. If they are loose, tighten them with a screwdriver. Loose screws can cause the hinge to become misaligned and prevent the door from latching properly.
Lubricating the Hinges
Apply a lubricant to the hinges. You can use a spray lubricant or a WD-40-type product. Lubrication will help the hinges move more smoothly and reduce friction, which can cause the door to stick.
Realigning the Hinges
If the screws are tight and the hinges are lubricated, you may need to realign the hinges. This can be done by removing the hinge pins, repositioning the hinges, and reinserting the pins. Make sure the hinges are perfectly aligned before reinserting the pins, as this will ensure that the door opens and closes smoothly and latches properly.
Adjusting the Hinge Plates
If the door is still not latching properly, you may need to adjust the hinge plates. This can be done by loosening the screws that hold the hinge plates to the door and frame, moving the plates slightly, and then retightening the screws. Make small adjustments at a time until the door latches properly.
Replacing the Hinges
If all else fails, you may need to replace the hinges. This is a relatively simple task that can be done with a few basic tools. Simply remove the old hinges and install the new ones in their place. Make sure the new hinges are the same size and type as the old ones, and that they are installed in the correct orientation.
| Problem | Solution |
|---|---|
| Loose hinge screws | Tighten the screws with a screwdriver |
| Stiff hinges | Apply a lubricant to the hinges |
| Misaligned hinges | Remove the hinge pins, reposition the hinges, and reinserting the pins |
| Improperly adjusted hinge plates | Loosen the screws that hold the hinge plates to the door and frame, move the plates slightly, and then retighten the screws |
| Worn or damaged hinges | Replace the hinges |
Leveling the Door Frame
If your door frame is not level, it can cause the door to bind and make it difficult to latch. To level the door frame, you will need a level, a shim, and a hammer.
Place the level on the top of the door frame and check if it is level. If it is not level, use a shim to level it. To do this, insert the shim between the door frame and the wall. Tap the shim with a hammer until the level is level.
Once the door frame is level, check if the door is now latching properly. If it is not, you may need to adjust the latch or strike plate. Here is a table summarizing the steps to level the door frame:
| Step | Description |
|---|---|
| 1. | Place the level on the top of the door frame. |
| 2. | Check if the level is level. |
| 3. | If the level is not level, insert a shim between the door frame and the wall. |
| 4. | Tap the shim with a hammer until the level is level. |
| 5. | Check if the door is now latching properly. |
| 6. | If the door is not latching properly, adjust the latch or strike plate. |
Inspecting the Weatherstripping
8. Inspect for Specific Alignment Issues with Weatherstripping:
Ensure that the weatherstripping strips are correctly aligned with the doorjamb. Shift the latch bolt slightly forward or backward to align the bevelled edge of the weatherstripping with the latch bolt. Inspect the alignment top and bottom (where the latch and deadbolt are located) and on the sides (where the door closes against the frame). Make minor adjustments as necessary to ensure the weatherstripping is straightened and flush with the doorjamb.
Additional Notes:
* Some weatherstripping types may require additional attention to ensure proper alignment. For instance, felt weatherstripping may need to be folded along its length to create a specific thickness.
* Pay close attention to weatherstripping that has been partially or completely stripped away, as it can result in alignment issues. In such cases, consider replacing the weatherstripping with a new one to restore sealing capabilities.
* If the weatherstripping is old, worn, or damaged, it may need to be replaced. Install new weatherstripping around the door frame to create a proper seal.
Troubleshooting Electrical Issues
If the latch is electrically operated, there are a few potential electrical issues that could prevent it from latching properly. These issues can include:
1. Faulty Wiring
The wiring to the latch may be damaged or loose, preventing it from receiving power. Check the wiring for any breaks or loose connections and repair or replace them as necessary.
2. Malfunctioning Solenoid
The solenoid is the electrical component that powers the latch. If the solenoid is malfunctioning, it may not be able to extend or retract the latch properly. Test the solenoid by applying power to it directly. If the solenoid does not operate, it will need to be replaced.
3. Faulty Latch Switch
The latch switch is the electrical switch that controls the latch. If the latch switch is faulty, it may not be able to send a signal to the solenoid to extend or retract the latch. Test the latch switch by pressing it manually. If the latch does not operate, the switch will need to be replaced.
4. Damaged Circuit Board
The circuit board is the electronic component that controls the latch system. If the circuit board is damaged, it may not be able to send the correct signals to the solenoid and latch switch. Inspect the circuit board for any damage, such as burns or broken traces, and repair or replace it as necessary
5. Blown Fuse
If the latch is powered by a fuse, the fuse may have blown, preventing the latch from receiving power. Check the fuse and replace it with a new one of the same amperage if it is blown.
6. Low Battery
If the latch is powered by a battery, the battery may be low or dead, preventing the latch from receiving power. Replace the battery with a new one.
7. Power Supply Failure
The power supply to the latch may have failed, preventing the latch from receiving power. Check the power supply and repair or replace it as necessary.
8. Electrical Interference
Electrical interference from other devices nearby may be disrupting the latch’s electrical system. Try moving the latch away from other electrical devices and see if that resolves the issue.
9. Troubleshooting Advanced Electrical Issues
If you have checked all of the above potential electrical issues and the latch is still not latching properly, there may be a more advanced electrical issue that requires further troubleshooting. This could involve testing the electrical components with a multimeter, checking the wiring diagram for the latch system, or consulting with an electrician for assistance.
