patio door lock repair
Over time, patio doors go through wear and tear that could lead to locks that fail. There are fortunately, a number of simple and effective methods that can restore your uPVC patio door's security.
These easy fixes can make your home safer no matter if you adjust the lock or clean the mechanism.
Clean the Lock
While patio doors are a great way to let in the outside and keep the elements out, they can also be a security risk when your lock isn't functioning as it should. As time passes, wear and tear, hot and cold weather dirt and debris could take their toll on the lock of your patio door and cause it to become difficult to open. With a little effort, you can make sure that the lock on your patio door always works correctly.
It's important to first clean the patio door lock and all moving parts. This will help remove any dirt and coatings that may be preventing the lock from functioning as it should. Start by wiping all the moving parts on your patio door lock using a wet cloth. Then, use a scouring cloth or rough damp cloth to scrub the dirt-infested parts of the door frame and frame. Then, wipe the lock down with a dry towel to get rid of any moisture. Let it air dry before you use it.
If you have an outdoor door that has pin tumbler latch mechanisms it is possible to lubricate the lock by applying powdered graphite to the key or by using an lubricant based on Teflon like WD-40 Multi-Use. This type of lubricant can be easy to apply and doesn't break down over time. If you are unable to find the right lubricant to use with your lock, you can apply a pencil that has a thicker tip. Insert the pencil in the lock, then shake it around to spread the graphite.
Regular maintenance is also essential to keep the tracks of sliding patio doors clear from dust, dirt and other debris. These tracks are especially susceptible to ice, snow, and other particles, which could cause them to get stuck or to bind. This could make it difficult for your patio door to open and close.
Sliding patio door track rails and rollers can be cleaned by removing dirty or damaged weather stripping, cleaning them, then installing it. The same applies for patio door rollers, which can be cleaned and sprayed with non-stick lubricant that will allow them to move freely.
Lubricate the moving parts
uPVC french doors, like sliding patio doors, work using 3 to 4 or sometimes 5-point locking mechanisms which include the lock cylinder and handle controlled by a key. They also require maintenance, specifically lubrication on the moving parts. This can be done using a thin oil, but never WD40. It should be done at least once a year.
If the hinges aren't causing the problem it could be because the door is not aligned. It may be rubbing against or catching the strike plate's opening in the frame. The solution is to take off the strike plate and then use an abrasive chisel to increase the size of the mortise that it rests in. This allows the latch to fit perfectly in the hole and prevents rubbing or catching on the frame.
While the cylinder is out of the way, measure its width with a book or piece of wood that can fit into the gap of adjustment screw above the lock. The outer dimension is the distance from the outside of the door to the middle of the cylinder. the inner dimension extends from the center of the adjustment screw to the end of the cylinder.
Check the lock's length
If your patio door latch is difficult to turn, even after cleaning and oiling it's possible that it's not aligned properly with the strike plate. Check if your door is in a balanced position, and that the hinge screws are tight. In many cases, moving the strike plate upwards or downwards will fix the problem.
The most common issue is when the lock's strike is too small for the latch to properly engage. In this instance, you can widen the opening with a chisel and hammer. Then test the latch to ensure that it doesn't rub against the jamb frame of the door or fall the frame.
It is important to identify the type of mortise lock you have before purchasing an alternative. This can be done by looking at the end faceplate and noting whether it is square or round. Look at each screw hole on the existing lock and note their dimensions. This information will aid you in finding an alternative lock that is of the same size and is a perfect fit for the hole you have already.
You'll need to identify the mortise lock, and then examine it for scratches, bends, or other damage that need to be fixed. A badly bent or damaged latch is more likely than one that has been used a lot to break. Replace the lock if it shows signs of damage.
After you've determined the type of lock replacement you require Now it's time to start the actual repair. Remove the handle and spindle out of your patio door, and then install the new one. Start by installing the interior handle. Align it with the spindle and then secure it in place using the two bolts or screws. Once the handle in the interior is in, install the handle that is outside and screw it in place, too. Once you've completed these steps, you can test the new handles to make sure they open and close easily and that the latch is catching properly with the strike plate.
Check the Door's Strike
The strike plate and door latch are two pieces which work together to secure the door. If these parts aren't aligned correctly and the latch doesn't latch the door shut correctly. Fortunately, the issue is often easy to fix.
First, examine the strike plate's receiving holes to ensure that they are clear of obstructions such as dirt or plastic plugs. Then loosen the keeper screws that secure the strike plate in place, allowing it to move vertically, but not detaching it from the frame of your door. Adjust the strike plate to align its holes for receiving with the latch hooks of the door latch. After the strike plate is adjusted, tighten all screws and check whether the door closes smoothly.
Door strike plates can be difficult to access for homeowners who have sliding patio doors, however they're essential to lock and unlock your door. These metal plates are usually located on the top and bottom of the door jamb, where they serve as the door's latch. The door latch is inserted into the strike plate, and it creates an airtight seal. If the strike plate has been damaged or rusted or not installed correctly, the latch may not lock the door properly.
A misalignment of the latch and strike plate is the most common reason for the patio lock not to close or remain in place. This can be confirmed using the "lipstick" test. Apply a little lipstick along the edge of the deadbolt and then cover it with masking tape. When you shut the door the lipstick will leave an impression on the tape that will show exactly where the latch connects to the strike plate. If the mark is too high or low you can adjust the strike plate.
If your patio door locks for sliding aren't working correctly, they can keep your home safe from burglars. You must fix this problem as soon as possible. If you follow these steps, you can repair your patio door's lock and regain its functionality in a matter of minutes.
