Replacing your sliding door lock can be a very difficult task to complete successfully, as sliding doors are vulnerable to intruders breaking the lock and entering. Replacing the sliding door lock for a better or more secure model is always a good idea and you should be able to buy the replacement lock at your local home improvement store. Following a few simple guidelines, you can complete this project yourself in a few hours.

Step 1 - Purchase Your Replacement Lock

Sliding doors comes in many different varieties and models, and finding the appropriate lock is your first challenge. You will need to know the door's manufacturer and the model number. This should be written somewhere on the door itself, so locating it shouldn't be a problem. You will then need to buy a lock that it suitable for your door, either by looking on the Internet, or contacting your local hardware store.

Step 2 - Remove the Old Lock

Once you have the new sliding door lock, you will need to remove the old one. Unlock the door, and slide it open until it touches the bumper at the back. Then, insert a door jam to prevent the door from sliding around while you are trying to get the lock free. Using your screwdriver, undo the screws around the old lock and pull it free. Your sliding door lock should be made of two separate parts held together by screws, so if you undo the door, the lock and external parts should fall apart, although you may need to pry off the lock if it has been on the door a long time.

Step 3 - Replace the Lock

Once the old lock is off, lightly grease the area which you have just exposed to the light, and then attach the new lock. If you have bought a suitable replacement for your make and model, you should be able to push the screws into the original holes and tighten. You will need to have assistance in holding the two parts of the new lock together while you tighten the screws. As the screws tighten, you should be able to see the two pieces line up with each other.

Step 4 - Check the Latch

You should now have a fully working lock. Remove the door jam, and slide the door closed. Try to lock the door, and check that the latch is in the correct position. If it is not, you may need to loosen the screws until the latch fits into its usual hole.
