If you want to better protect your home, then you should install reliable locks, especially on your sliding patio door. You can do this very simply by just following a few rules on removing the old lock and fitting the new one. This can make a lot of difference in the accessibility of your door and add a great deal more protection for your well being. In order to install a sliding patio door lock, you will need to have a drill, and it is also useful to have a friend who can help you position the lock. By following a few simple steps, you should be able to have the door lock fitted very quickly.

Step 1 - Make sure it closes properly.

In order to install the sliding patio door, you will first need to make sure that it closes properly. This could involve cleaning out the base of the door and the track with a brush to loosen up the dirt and a vacuum cleaner to pick it up so that the door fully touches the edge of the corresponding frame style. It is rare for people to realize that the door might not be fitting tightly into position, but you will need to push it tightly into location so that you have no problems fitting the lock. Having someone keep the door tightly closed while you install the lock will ensure a tighter fit.

Step 2 - Position the Lock

Once the door has been closed, you can take the new lock, and hold it at the edge of the door, next to the frame. The lock needs to be positioned so that it is close to the door latch, as some locks work by preventing the latch from moving backward. Keeping the lock and latch tightly engaged during installation will also prevent thieves later on from being able to pull the sash from the frame style to squeeze a slim-jim through the gap.

Step 3 - Drill the Lock Holes

Hold the lock steady in its proper location on the door style and mark the location of every hole before drilling each one through the door style where they should line up with the ones on the handle's faceplate. Once the holes have been made, you can then screw the lock into the door. After securing the lock in place, position the latch on the frame directly opposite to the lock and trace it out with a pencil. You can then slide open the sash and fasten the latch in place with the supplied screws. The latch should line up perfectly with its locking mechanism.

Step 4 - Finishing Up

With that completed, you can then add the cover plates if this is the case. Screw them onto the door, on top of the lock, and then move it around so that it can be joined to the bolts.
