Sliding Glass Door Lock: Step-by-Step Instructions Sliding Glass Door Lock: Step-by-Step Instructions
Add a lock to your sliding glass door to give your home added security. There are several ways to secure this type of door. Read on to learn about different types of locks and installation.
Step 1 - Use a Blocking Device
Even if your door already has a lock, it’s may not be enough. These locks can jam, stick or just fall apart. For extra security, add something that blocks the door from sliding in the track. You can use something as cheap as a broom handle or a wooden dowel.
Alternatively, you can install a ‘charley’ bar, which screws into the frame at the back of the door. To operate, simply pull the arm and attach it to the back of the door.
Step 2 - Determine the Door Material
The material of your door will determine the tools you will need to install a new lock. Most glass doors are made of aluminum, so you can use a specialized drill bit. You will likely need to bore holes in the door frame for the lock.
Some doors are made of a nylon plastic. These types of doors will only need a standard drill bit, and you don’t need to have any kind of special tools.
Step 3 - Prepare for Installation
The next step is to find where the glass ends inside the door. Mark this spot so you know not to drill through it.
Line up the new locking bolt in the place where there isn’t any glass. Mark the screw hole locations for the new lock.
Use a punch to create a marker and guide for the drill. It’s important to remember that you are working near glass. If you aren’t entirely certain about the placement, you risk drilling through and shattering the glass.
Step 4 - Begin Installing the Lock
Gently screw the new lock in place. With the first screw in position, mark for the second one. Punch another hole here and drill it in place.
Secure the lock in place, and mark the outline where the bolt will hit the frame of the door.
Step 5 - Create a Bolt Hole
Use a 1/8-inch bit to create a pilot for the hole. Every few seconds, pause to ensure you aren’t hitting the glass. You will eventually want this hole to be ½-inch.
Test the lock and make sure everything is working correctly. If it is, just tighten the screws and enjoy the security your new lock brings.
