Check the lock
Patio doors are frequently targeted by burglars because of their large amounts of glass and their central location within a home. A lock that is functional and secure is important to ensure your home's security. There are easy solutions to repair patio door locks that have stopped functioning.
The first step is to examine the lock to ensure nothing is hindering it from latching or locking. If you find any issues such as loose screws or rust, or even an issue with alignment, they should be addressed promptly. In some cases, a slight adjustment to the door's location could be enough to solve the problem.
Dust or debris could cause the lock mechanism not to perform as it should. To avoid this happening, ensure that you clean your patio door frequently and wipe down the lock hardware. You can make use of a mild detergent when needed, but remember to dry the lock thoroughly afterward.
In addition, it's recommended to oil the lock on a regular basis. The moving parts of your uPVC patio door lock are similar to the parts of a fine-tuned machine, so they can become stuck and jammed like any other mechanical device. Using graphite pencils or a light lubricant can help to dislodge any dirt or debris that has collected within the lock cylinder and keep it operating smoothly.
Identifying the exact dimensions of your patio door lock is also crucial. This will help you find the perfect lock to match your existing mechanism. If you're not sure how to proceed you can contact an expert locksmith or tradesperson for assistance.
Clean the Lock
The intricate parts of the door lock may jam up over time because of dirt, dust, and hot and cold weather. These problems can compromise your home's security. These issues are easy to fix if you know what to do.
Clean your lock before attempting any repairs. Clean up any stains or debris with a damp cloth. Then, use a little hot soapy water to clean the mechanism of the lock and get rid of any dirt or grime that has accumulated over time. After you've cleaned your locks, allow them to dry completely before re-using them.
Most patio doors are secured by mortise locking mechanisms. This is a safe lock but can develop issues in time. If your uPVC lock has become stuck the first step is to clean and lubricate it. For an uPVC lock it is best to begin by cleaning the latch plate using a small amount of soapy water. The next step is to loosen the screws that keep the latch in the position. After removing the latch plate and handle and handle, you can then remove it from its slot on the door frame.
Once the latch is removed, you can lubricate it by using a lubricant for engineering like WD40. If you don't have WD40, a graphite pen can be used to remove dirt and grit off the mechanism. If your uPVC locks are still not working, you may need to reposition your lock cylinder. This requires additional tools and is best done by an expert. But you can practice moving the cylinder around without removing it from the door by opening and closing the door with the cylinder in the lock position, and then drawing pencil marks on the inside of the frame where the screws are that hold the cylinder in place.
Lubricate the Lock
Once your lock is clean and free of dirt and other debris, it's time to grease the keyhole as well as the locks themselves. Using the correct type of lubricant can keep your lock in good shape, extending its lifespan.
Dry graphite powder is excellent for lubricating small metal parts like locks since it's not sticky or oily and lasts longer than liquid lubricants. It's easy to apply and you can use it on sliding doors, door hinges and garage door tracks. Master locksmith Shawn Fago recommends using a pencil-type graphite lubricant that is designed specifically for lock cylinders.
Liquid lubricants are more efficient than graphite powder especially in humid climates. Silicone lubricants are water resistant and will not attract as much dust or dirt as other kinds of liquid fluids. They work well at high and low temperatures. Certain silicone lubricants build up over time, and displace other lubricants you've tried.
Teflon-based lubricants are an excellent alternative to silicone lubricants since they last longer and don't attract dust and dirt. They are also great for cold conditions, since they prevent the build-up of ice inside the lock.
If your lock's cylinder seems extremely stiff and hard to turn, it's likely worn out and needs to be replaced. A professional locksmith can disassemble the lock mechanism and replace it with a the new cylinder that matches the keys you have. They can also make repairs and adjustments to existing lock mechanisms. A professional can install a new lock cylinder if your door isn't equipped with one. This can increase safety and security. They can also install new lock faceplates on your patio door to match the rest of the door.
Reposition the Lock Cylinder
If lubricating the lock and cleaning it do not perform, the issue could be that the latch is not properly aligned with the side jamb or the frame of the door. Open the sliding patio doors and examine the top and bottom of the latch opening. If the door is in line with the jamb or the frame then you can test. If not, loosen screws holding the latch body and adjust it downwards or upwards until the latch is firmly grasping the latch hasp when the door is closed.
Sometimes the latch can be difficult to close due to a worn-out or damaged cylinder. You'll need a replacement for the cylinder when the worn one is making it difficult to turn the key. You should select one with the same keyway and dimensions as the previous one. This will allow you to replace it with ease by unbolting the two halves before inserting the replacement cylinder.
Many home improvement stores carry replacement cylinders. You'll be required to know the name and model of the existing cylinder to be able to purchase one that matches it. If you don't know the model and manufacturer, take a photograph of the cylinder along with its mounting screws. Then go to your local hardware store for help.
When you have a new cylinder, remove the screw with a flat head that holds it in place and remove the plate that holds it in place. Remove the lock cylinder, the escutcheon and door frame using the help of a screwdriver. Put the screw in a secure place so that you don't lose or damage it. Then, loosen enough the set screw that is located on the cylinder keep (the metal piece that fits into the rectangular hole of the door).
Replace the Lock

It's not uncommon for dirt and debris to get stuck inside the lock's mechanisms, but if this isn't addressed promptly, the lock can eventually break down and cease to provide security.
