Why Garages Are Targeted

Garages are attractive to burglars for three reasons: they contain valuable items (tools, bikes, vehicles), they often have weak security compared to the main house, and attached garages provide interior access to the home.

Many garage break-ins exploit a small number of common weaknesses. Addressing these 10 points can help reduce your risk.

1. Upgrade to a Roll-Up Door

Standard sectional garage doors have panels that can be pried apart and emergency release cords that can be triggered from outside with a coat hanger. Roll-up garage doors are designed without either — the continuous curtain has no panels to separate and no external release mechanism.

2. Add a Manual Lock

Even motorized doors benefit from a manual deadbolt or slide bolt lock. Engage it when you leave for vacation or at night. This provides a physical backup that doesn't depend on the opener's electronics.

3. Secure the Interior Door

If your garage connects to your house, treat that interior door like an exterior door — solid core, deadbolt lock, and reinforced strike plate. Many homeowners leave this door unlocked or use a flimsy hollow-core door.

4. Cover the Windows

Garage windows let burglars case the contents. Frost the glass, add curtains, or install window shutters. If they can't see what's inside, they're less likely to risk entry.

5. Install Motion-Activated Lighting

Bright motion lights on the exterior can help deter approach. Place them above the garage door and along the driveway or laneway. LED flood lights are inexpensive and effective.

6. Use a Smart Garage Controller

Smart controllers alert your phone when the garage opens and let you close it remotely. Some integrate with home security systems to trigger cameras or alarms when the door opens outside scheduled hours.

7. Don't Leave the Remote in Your Car

A garage door remote clipped to the visor is an invitation. If your car is broken into, the thief now has access to your garage. Use a keychain remote you carry with you, or a smart-phone-controlled system.

8. Reinforce the Track

For sectional doors, a C-channel track lock or padlock through the track prevents the door from being forced open. For roll-up doors, the guide rail design is intended to resist this type of attack.

9. Add a Camera

A visible security camera above the garage can act as a deterrent. Modern Wi-Fi cameras are affordable and provide instant phone alerts with video clips.

10. Maintain Your Door

A well-maintained door operates reliably and closes fully. A misaligned or damaged door may leave gaps that compromise security. See our maintenance guide for tips on keeping your door in top condition.

Common Questions

Garage Security FAQ

What are common weak points on a garage?

Common weak points are the garage door itself, the door into the house, windows and remotes. On sectional doors, panels can be pried apart and the emergency release cord can sometimes be reached from outside. A hollow-core or unlocked door between the garage and house, uncovered windows that show what is inside, and a remote left in a parked car are other gaps worth addressing.

Are roll-up garage doors more secure than sectional doors?

Roll-up garage doors are built without two sectional-door features that can be exploited: separate hinged panels and an emergency release cord that can sometimes be reached from outside. Their interlocking aluminum slats run in reinforced side guides and form a continuous curtain. No door makes a garage break-in proof, so treat a roll-up door as one layer alongside locks, lighting and cameras. See roll-up garage doors.

Should I add a manual lock to a motorized garage door?

A manual lock is a sensible backup. A deadbolt or slide bolt gives a motorized garage door a physical lock that does not depend on the opener's electronics, and it can be engaged at night or while you are away. Roll-up doors can also be fitted with key-lock operation, so ask about locking options for your opening at the free onsite consultation.

How should the door between the garage and house be secured?

Treat the door between an attached garage and the house like an exterior door, with a solid-core slab, a deadbolt lock and a reinforced strike plate. Hollow-core interior doors and doors left unlocked are common weak points, because once someone is inside the garage, that door leads into the home. Keep it locked even when the main garage door is closed.

Can roll-up shutters be installed on garage windows?

Yes. Garage windows can be fitted with roll-up shutters that close over the glass, so the contents of the garage are not visible from outside. Frosted glass or curtains are simpler alternatives. Roll-up window shutters are custom-measured to each opening and can be motorized or manual. See window security shutters for residential examples.
