How to Repair a Bad Patio Door Lock
A secure patio door is vital for home security. If it is difficult to lock, it can be a hassle.
In many instances, a locked that is not working is due to an incorrect alignment or simply wear and tear. It's possible to restore the function of the lock by adjusting or lubricating the lock. If these troubleshooting techniques aren't working, you can replace both the mortise as well as the handle.
Clean and Lubricate
Over time, dirt, dust and grime can make it difficult to open and close a door lock. Regular cleaning and lubrication routine can keep your security device from becoming stiff or stymied, saving you money on repair bills and allowing your door to enjoy its full lifespan.
To begin, you'll need to clean the lock's the cylinder. Make use of WD-40 or another penetrating spray to accomplish this. Spray a small amount oil into the keyhole, and then rotate the key to distribute the oil. Avoid using household solvents or other oils that could damage your locks. Also, make sure you spray some on the key itself as well.
When your lock's cylinder is clean, it's time to lubricate. You can use dry lubricants like graphite powder or sprays of silicone. Graphite powder has a long life and doesn't attract dust like liquid lubricants do, so it's an excellent choice for lubricating locks that stick. Silicone sprays can endure temperatures of minus 0 degrees and are resistant to water. However, they may need multiple coats in order to be effective.
You can also use a de-icer spray, which is specifically made for colder weather and will lift frost and ice off the lock mechanism. This will enable you to unlock your lock and then unlock it with ease.
How often you need to oil your locks will be contingent on the environment. A coastal location exposes your door to salty air, which can cause corrosion, and temperature fluctuations can also impact the efficiency of your lock. It is recommended that you lubricate locks at least two times every year, or more frequently in areas with harsh weather conditions. Lubricating your locks will save you money on repairs and ensure your patio door will function properly for long time to come.
Reposition the Lock Cylinder
If your patio door lock doesn't function properly, one or more of its parts may be damaged or misaligned. Regular inspection and prompt repair of a faulty patio door lock can prevent further damage and ensure that your doors are secure. To fix a locked or non-locked patio door, tighten loose screws, adjust the lock mechanism or replace the lock cylinder.
Begin by inspecting the exterior and interior of the lock to find signs of damage or misalignment. The patio door locks can expand or contract in response to the weather, and may even shift over time. This slight movement could cause the locking mechanism to not align properly and can cause issues when opening or closing the patio door.
Then, check the lock cylinder for obstructions within the keyway hole. If the lock is corroded or blocked, the cylinder may be difficult to open and may eventually cause damage to the lock pins, cam or latch springs. If the cylinder doesn't fit easily, you can get rid of any obstructions with a pair of picklocks and tweezers. If the issue persists, you may need to remove the cylinder and disassemble it in order to identify the cause of the obstruction.
If the lock cylinder isn't screwed into the lock body you can loosen it by removing a flat screw inside the cylinder faceplate. Loosening this screw will allow you to rotate the cylinder and may help to restore alignment.
Examine the cylinder for a tiny tab that moves up and down with the key, usually towards the end. This small clip, also known as a "release Tab" will stop the cylinder from sliding into the lock body all the way. A standard key can move the tab back to allow the cylinder to be released and allow it to be removed and reinserted.
If the lock cylinder has become stuck and is not aligned, you can fix it by rotating the cylinder until the latch bolt is engaged with the strike plate. The handle or knob may then be pushed and withdrawn. Reassemble the lock once you have restored alignment. Test it for functionality. If your patio door lock is still difficult to use, it's a sign that a component, like the latch spring or latch is damaged or worn and will need to be replaced.
Make sure you tighten the Screws
The locks on patio doors are susceptible to damage from regular use, extreme temperatures, dirt and dust. These delicate components can be damaged if they are not maintained properly, causing your door to not lock properly. Fortunately, most lock issues are easily fixable by following a few easy maintenance steps.
The first thing to do is clean the lock mechanism. Use a damp cloth to remove any dirt or dust that might be present. Then dry the parts thoroughly. After cleaning, a small amount silicone-based lubricant will help keep the moving parts operating smoothly and efficiently. Avoid lubricants with oil bases because they may attract dust and other debris and cause additional issues.
If your patio door has a foot lock that is secure be sure that the foot lock is properly aligned with the strike plate. In the majority of cases, this will only require adjustment of the screws that hold the foot lock to the frame of your patio door. Unlock the screw with the Robertson screwdriver, and gently move it upwards or downwards to adjust the foot lock as required. After the adjustment is completed then tighten the screw.
The most frequent issue when it comes to fixing patio door handles is the misalignment of the latch and strike plate. This could be due to the wear and tear of everyday use or it could be that the latch is set higher or lower than it should be.
Start by removing the handle, then find the screws or bolts that secure it. Keep track of the bolts or screws as you will require them to install the new handle. Next, remove the old spindle, and then slide the new one into position on the inside of the door, making sure that it is aligned with the holes in the interior and exterior handles. Reinstall the exterior and interior handles once the spindle is been installed. Make sure that they are aligned properly with the bolts or screws holding them in place.
Close and secure the patio door after you have made any necessary adjustments. If the door is properly aligned, it will open and close smoothly without the need for any additional force. If you are still having issues, you may need to reposition your strike plate or latch, or replace the lock cylinder.

Before you install the new latch, loosen the screws securing the strike plate (the part of the lock that's mounted on the outside edge of the door frame) and adjust it horizontally or vertically to align it with the latch hole in the door jamb. After you've adjusted the strike plate, screw it into position and tighten the screws.
After all the parts of your patio door are repositioned or replaced, reassemble and secure them according to the instructions given by the manufacturer.
