Protecting Your Home: Garage Door Security Best Practices

2025-12-20 8 min read Sarah Williams

The garage door is often called the "forgotten door" when it comes to home security. While homeowners invest in quality locks, security systems, and cameras for their front doors, the garage door—often the largest opening in the home—receives far less attention. Statistics show that 9% of burglars enter through the garage, making it the second most common entry point after the front door. In this guide, we'll explore how to secure your garage door and protect your home.

Understanding the Vulnerabilities

Before we discuss solutions, let's understand how burglars exploit garage doors:

The emergency release handle, designed to let you open the door during power outages, can be triggered from outside using a simple wire or coat hanger slipped through the top of the door.

Older remote controls use fixed codes that can be captured and replayed by code-grabbing devices, giving thieves access to your garage.

Windows in garage doors allow potential burglars to see inside—including whether your car is there—and may provide access to the emergency release.

Connected garages (those with a door leading into the home) give intruders access to your entire house once they're in the garage, often through a less-secured interior door.

Essential Security Measures

Here's how to address these vulnerabilities and secure your garage:

Install an automatic garage door lock or deadbolt. While most modern openers have built-in locks that engage when the door is fully closed, adding a manual deadbolt provides an extra layer of security, especially when you're away for extended periods. Automatic locks engage whenever the door closes and disengage when you use the opener.

Secure the emergency release. The emergency release handle hangs from a cord attached to a lever that, when pulled, disconnects the door from the opener. You can purchase a shield that prevents the lever from being triggered by a wire inserted through the door's top seal. Another option is a zip tie that requires cutting to use the release—a minor inconvenience that significantly improves security.

Upgrade to a rolling code opener. If your opener is more than 20 years old, it may use a fixed code that can be captured. Modern openers use rolling code technology that changes the access code with every use, making code grabbing impossible. This upgrade alone significantly improves security.

Cover or frost garage door windows. If your door has windows, consider covering them with privacy film or replacing them with frosted glass. This prevents anyone from seeing whether your car is home—a detail burglars use to determine if a house is occupied.

Install motion-sensor lighting. Burglars prefer to work in darkness. Motion-activated lights on the exterior of your garage make the area less appealing for unauthorized access. Modern LED motion lights are inexpensive and easy to install.

Securing the Interior Door

If your garage is attached to your home, the door between them deserves serious attention:

Upgrade to a solid-core door. Many builders install hollow-core interior doors between the garage and home. Replace this with a solid-core or metal door rated for exterior use.

Install a quality deadbolt. The garage-to-home door should have a deadbolt lock just like your front door. Make sure the strike plate is secured with 3-inch screws that reach the door frame's studs.

Add a peephole or window. Being able to see into the garage before opening the door can be a valuable safety feature, especially at night.

Consider a door reinforcement kit. These kits strengthen the door frame and make the door much more resistant to kicking or forced entry.

Smart Security Features

Modern smart openers offer security features worth considering:

Real-time alerts notify you whenever the garage door opens or closes. If someone opens your door while you're at work, you'll know immediately.

Activity logs show a complete history of door activity, including when it was opened, when it was closed, and whether it was operated manually or remotely.

Automatic closing can be set to close the door after a specified period—say, 5 minutes—if it's been left open. This prevents you from accidentally leaving the door open overnight.

Remote locking allows you to engage the opener's lock feature from your phone, preventing the door from being opened even with a valid remote.

Integration with security systems means your garage door can be monitored as part of your home security system, triggering alarms if opened during armed periods.

Additional Security Tips

Don't leave your remote in your car. A remote left in a parked car, especially one parked outside overnight, gives anyone who breaks into the car access to your garage. Use a keychain remote or smartphone app instead.

Keep the garage door closed. This seems obvious, but many homeowners leave the garage open while doing yard work or when home during the day. A closed door is always more secure than an open one.

Secure valuable items. Even with a secure door, the garage shouldn't be used to store high-value items visible from the street when the door is open. Lock bikes, tools, and other valuables in cabinets or a separate locked area.

Maintain your door. A well-maintained door not only operates better but is also more secure. Worn weatherstripping, misaligned tracks, or damaged panels can create vulnerabilities.

Don't advertise absences. If you're going on vacation, don't rely solely on timers and smart locks. Have a neighbor collect packages and check periodically that everything looks normal.
