Before we proceed to step-by-step instructions, let’s find out how this lock works and how to prepare before the garage door lock installation.

A garage door slide lock is also called a side lock or latch, commonly used as an inside or outside lock on overhead garage doors. Typically, it is a metal bar or rod that can be manually inserted into the track or rail of the garage door to prevent it from being opened.

When engaged, it extends into the track and holds the door in a closed position, effectively immobilizing it. This makes it difficult for someone to force open the garage door from the outside, even if they bypass the door’s locking mechanism.

To get ready to install a lock on a garage door, you should get the necessary tools and materials:

  • A lock kit usually includes a slide lock, screws, and a handle. Notably, locks are available in a variety of shapes and sizes, so make sure you choose the one that will match your door;
  • Screwdriver;
  • Drill and drill bits matching the screw size;
  • Marker.

With an installation set at hand, the whole process won’t take more than 5 minutes.

1. Prepare the Door

To install garage door locks safely and correctly, move the door into a locked position and disconnect an automatic opener first. This will help you determine the correct placement of the lock. Besides, you’ll rest assured that no one will accidentally open the door during installation.

2. Determine the Lock Position

Locate the area on the garage door where you will install the slide lock. It should be normally installed in the center, near the bottom of the door. This location will ensure stability and security.

Most doors have a special slot for garage door lock bar installation. Place the slide lock against the door to ensure it aligns properly with the slot on the door track. Besides, watch for placing it at some distance from the door edge to prevent the lock’s body from hitting the door.

3. Mark the Mounting Holes

Once you have determined the proper placement for the garage door lock install, mark the mounting holes on the garage door. Use a marker to make small dots at the center of each hole. Double-check the alignment and make adjustments if necessary.

4. Drill Pilot Holes

Once you finish with all the measurements, you can start drilling pilot holes at the marked spots. Pilot holes will help guide the screws during installation and prevent the wood from splitting. The holes should be deep enough to hold the screws securely.

5. Install the Lock

Align the lock with the holes in the garage door and insert the screws through the mounting holes. Use a screwdriver or drill to tighten the screws, ensuring the lock body is securely attached to the door and doesn’t move. To ensure smooth and long operation, lubricate all the moving parts.

6. Test the Lock

To make sure the lock is properly aligned and functioning, open the garage door slightly and engage the latch by sliding it into the locked position. Fully close the door and check if the lock holds.



A slide lock is a simple yet efficient additional security measure that can help you reinforce the locking mechanism of your garage door. This will provide an extra layer of protection for your belongings and give you peace of mind about your garage door being additionally protected against break-ins.

Where is the best place to put a lock on a garage door?

A common place for garage door lock bar installation is a central part of the door above the bottom section. This placement ensures great stability of the locked door and convenient use. Ensure the lock is properly centered and its body doesn’t stick out to avoid hitting the door.

How do I secure my garage from thieves?

In most cases, a slide lock is an additional security measure to keep your garage securely closed in case of power outages or ensure protection from kids that tend to open the door from the outside. Such locks are commonly combined with other security measures, such as locking handles, keypads, or remote control systems.

To further enhance your garage protection from break-ins, consider installing lights with motion sensors to frighten burglars away. Reinforce the top edge of the door with protective metal plates to prevent thieves from pulling out the cord to open the door. Finally, consider installing a home security system to keep burglars at bay.

What is the best lock for garage doors?

When considering additional garage door lock installation, you will have to choose between keyed, electronic, and automatic locks. Which type is the best option for you will depend upon your security needs. A deadbolt lock is by far the most secure. In the meantime, automatic deadbolt locks are harder to break. Smart locks offer added convenience and can be integrated into a smart home system for complex protection.
