How to Repair a Bad Patio Door Lock

A safe patio door is a crucial element of home security. It can be difficult when it isn't easy to lock.

In a lot of cases, a stubborn lock is due to misalignment or simple wear and tear. Lubricating the lock or changing its position may help restore its function. If these solutions don't work you can replace both the mortise and handle.

Clean and Lubricate

Over time, dust, dirt and grime can make it difficult to open or close the door lock. A regular cleaning and lubrication routine will stop your security device from becoming stiff or stuck, saving you money on repairs and helping your door reach its full potential.

To begin, you'll have to clean the lock's the cylinder. To do this, you'll need a spray bottle of penetrating oil such as WD-40. Spray a small amount oil into the keyhole and then rotate the key to spread it. Avoid using household oils or other solvents that could damage your locks, and make sure to spray a little on the key itself as well.

After cleaning your lock cylinder, it's time to lubricate. You can apply a silicone spray or dry lubricant such as graphite powder. Graphite is a lubricant that lasts for a long time that doesn't attract dust unlike liquid lubricants. It's an excellent choice for locking lubrication. Silicone sprays can withstand freezing temperatures and are impervious to water. However, they might require multiple coats to be efficient.

You can also apply sprays for de-icing, which is specifically made for cold weather and will loosen ice and frost from the lock mechanism. A few sprays of this will help your lock to unlock and then lock again easily.

How often you have to lubricate your locks will rely on the environmental conditions. The location of your door will affect its performance. A location that is near the ocean can expose the door to salty air, which can cause corrosion. It is recommended to ensure that your locks are lubricated at least twice every year, or more frequently in areas with harsh weather conditions. Lubricating your locks will save you money on repairs and ensure that your patio door continues to perform as it should for years to come.

Reposition the Lock Cylinder

If your patio door lock isn't functioning properly, it could be that one or more parts are damaged or misaligned. Regular inspections and prompt repairs of a damaged lock on your patio door will help prevent further damage and guarantee the security of your doors. To fix a locked or non-locked patio door, you can tighten loose screws or adjust the lock mechanism, or replace the lock cylinder.

The majority of patio door locks expand and contract during temperatures that are cold or hot and can shift slightly over time. This slight movement may cause the locking mechanism to be misaligned and cause problems when opening or closing the door.

Examine the keyway hole of the lock cylinder. If the lock is corroded or blocked, the cylinder can be difficult to open and can eventually cause damage to the lock pins, cam, or latch springs. If the cylinder does not fit easily, you can remove any obstructions with a pair of tweezers and a lock. If the issue persists, you might need to remove the cylinder in order to locate the source.

If the lock cylinder hasn't been screwed into the body of the lock then you can loosen it by uncrewing an elongated screw within the cylinder's faceplate. This screw will allow you to rotate the cylinder and may even help restore the alignment.

Look for a small tab that moves along with the key. It's usually at the end. This tiny clip, referred to as a "release tab" prevents the cylinder from sliding into the body of the lock. 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 is stuck it is possible to restore alignment by rotating the cylinder until the latch bolt is engaged with the strike plate. The knob or handle can then be pulled and withdrawn. Once you have restored the proper alignment, you can reassemble the lock and test its functionality. If the lock on your patio door isn't working properly, it is likely that a different component, such as the latch or latch spring requires replacement.

After cleaning, a small amount silicone-based lubricant can keep moving parts running smoothly and efficiently. Avoid lubricants that have oil bases as they can attract dust and debris which could cause more issues.

If your patio door is fitted with a security footlock, ensure that the footlock is aligned properly with the strike plate. In most instances, this will require adjusting the screws that secure the foot lock to the frame of your patio door. Remove the screw using the Robertson screwdriver and gently pry up or down to adjust the foot lock as needed. Once the adjustment is done then tighten the screw.

The most frequent issue in the repair of patio door handles is the misalignment of the latch and strike plate. This can be caused by the wear and tear of everyday use or it could be that the latch is placed higher or lower than it ought to be.

Then, take off the handle that was previously used and locate the bolts or screws that are holding it in the first place. Make sure you keep track of these since you will need them when installing the new handle. Then, take off the spindle that was in use and slide the new one on the inside of the door. Make sure it is aligned properly with the holes in both the exterior and interior handle. Once the new spindle is in place put back the interior and exterior handles to ensure that they are in alignment with the screws or bolts that secure them.

Close and lock the patio door once you have made any adjustments that are required. If the door is properly aligned, it should be able to open and shut smoothly without needing any additional force.
