How to lock a garage door from the inside?


Locking a garage door from the inside is an essential security measure to protect your home and belongings. Whether you want to secure your garage while you’re inside or prevent unauthorized access from the outside, there are several methods you can use. In this article, we will explore different ways to lock a garage door from the inside, providing you with the knowledge to enhance the security of your garage.

1. Slide Bolt Locks

One of the most common and effective methods to lock a garage door from the inside is by using slide bolt locks. These locks are typically installed on the inside of the garage door and can be manually engaged to secure the door. Slide bolt locks are simple to use and provide a sturdy barrier against forced entry.

To install a slide bolt lock, you will need a drill, screws, and a measuring tape. Start by determining the appropriate height for the lock, ensuring it aligns with the corresponding strike plate on the door frame. Once you have marked the position, drill pilot holes and attach the lock using screws. Test the lock to ensure it functions properly before relying on it for security.

2. Padlocks and Hasps

Another effective method to lock a garage door from the inside is by using padlocks and hasps. This method is particularly useful if your garage door has handles or loops that can accommodate a padlock. By installing a hasp on the door and securing it with a padlock, you can prevent the door from being opened from the outside.

To install a padlock and hasp, you will need screws, a drill, and a padlock that fits the hasp. Begin by attaching the hasp to the door using screws, ensuring it is aligned properly. Then, close the door and mark the position on the door frame where the hasp will meet. Drill pilot holes and attach the strike plate. Finally, insert the padlock through the hasp and lock it to secure the door.

3. Door Reinforcement

In addition to traditional locks, reinforcing your garage door can provide an extra layer of security. Door reinforcement kits are available, which include metal plates and bars that can be installed on the inside of the door to strengthen it. These kits can help prevent the door from being kicked in or forced open.

To reinforce your garage door, follow the instructions provided with the kit. Typically, you will need to attach metal plates and bars to the door using screws or bolts. Ensure that the reinforcement is properly aligned and securely fastened to maximize its effectiveness.


Securing your garage door from the inside is crucial for the overall security of your home. By using slide bolt locks, padlocks and hasps, or reinforcing the door, you can significantly enhance the protection of your garage and belongings. Remember to choose a method that suits your needs and install it correctly to ensure optimal security.
