How to Secure a Garage Door From Break Ins

How to Secure a Garage Door From Break Ins

Your garage door isn’t just an entry point for your car—it’s often one of the most vulnerable access points to your entire home. While you might have invested in solid front doors and secure windows, many homeowners overlook their garage as a potential security weak spot. The reality is that burglars know this, and they’re increasingly targeting garage doors as an easy way into homes across Australia.

Whether you have an attached garage that provides direct access to your living spaces or a detached garage storing valuable tools, bikes, and equipment, understanding how to secure your garage door properly is essential for protecting your property and family. The good news? With the right combination of hardware upgrades, smart technology, and simple habits, you can significantly reduce your risk of garage break-ins. If you’re unsure where intruders might gain access, our garage door problem identification guide explains common weak points.

Why Garage Door Security Matters

Garages have become prime targets for burglars, and it’s not hard to see why. An attached garage offers thieves direct access to your home, often through an internal door that may have less robust security than your front entry. Once inside the garage, they can work out of sight from neighbours and the street, taking their time to gain entry to the main house or load up on valuable items.

The items stored in modern garages have also changed dramatically. Beyond cars, many Sunshine Coast residents store expensive bikes, power tools, sporting equipment, gym gear, and even spare electronics in their garages. The combined value can easily reach tens of thousands of dollars, making garages increasingly attractive targets.

Police reports consistently show that garage break-ins are among the most common property crimes in suburban areas, with many occurring during daytime hours when homes appear empty. The concerning part? Many of these break-ins are preventable with proper security measures.

Common Ways Burglars Break Into Garages

Understanding how thieves gain access to garages is the first step in securing yours effectively. Here are the most common methods burglars use:

Outdated or poorly maintained garage doors often have weak points that experienced thieves know how to exploit. Older sectional doors with worn tracks, damaged panels, or failing automatic openers can be forced open with minimal effort and noise. Security issues often start with faulty openers — review our guide on common garage door opener problems to avoid easy break-ins.

Emergency Release Cord Exploitation

The emergency release mechanism—that red cord hanging from your garage door opener—is designed to help you manually open the door during power outages. Unfortunately, it’s also a burglar’s best friend.

Emergency Release Cord Risks

The “coat hanger trick” or “fishing the release cord” is a well-known technique among thieves. If there’s even a small gap at the top of your garage door (common with roller doors and some sectional doors), a burglar can slide a wire coat hanger or similar tool through the gap, hook the emergency release cord, and pull it. This disengages the automatic opener, allowing them to lift the door manually.

The entire process takes less than 30 seconds and leaves minimal evidence. Shielding this mechanism or installing a garage door that fits flush to the header are effective countermeasures.

Remote and Smart Tech Weaknesses

Older garage door remotes that use fixed codes are vulnerable to code grabbing. Thieves with the right equipment can capture your remote’s signal and replay it to open your door later. Additionally, if you leave your remote in your car (particularly if you park on the street or in an unsecured driveway), a quick smash-and-grab gives thieves a key to your garage.

Even smart garage door systems can be vulnerable if not properly configured, especially if they’re connected to unsecured Wi-Fi networks or use weak passwords.

Secure Your Garage Door Access Points

Managing how you and your family access the garage is crucial for maintaining security. Preventive care is essential for security — our guide on common garage door problems and how to prevent them explains why.

Keep remotes secure: Never leave garage door remotes in cars parked outside. Consider using a keychain remote that you carry with you, or better yet, a smart garage door opener controlled through your smartphone with biometric authentication.

Upgrade to rolling code technology: Modern garage door openers use rolling code technology that generates a new code each time you use the remote. This makes code grabbing virtually impossible. If your opener is more than 10-15 years old, upgrading to a rolling code system is one of the best security investments you can make.

Install or upgrade wall-mounted keypads: If you use a keypad for garage access, ensure it’s a modern model that won’t reveal worn numbers from repeated use. Change your access code regularly, and avoid obvious combinations like birthdates or sequential numbers.

Upgrade Locks and Garage Door Hardware

Upgrade Locks and Garage Door Hardware

Physical security upgrades provide reliable, low-tech protection that doesn’t depend on batteries or internet connections.

Manual locks: Installing a manual deadbolt or slide bolt on the inside of your garage door adds a simple but effective layer of security. When you’re away for extended periods, manually locking your garage door prevents it from being opened even if someone compromises your automatic opener.

Anti-lift devices: These prevent the door from being forced up from the outside. Many newer garage doors include anti-lift features built into the track system, but older doors can be retrofitted with security bars or brackets.

Automatic and Smart Locking Technology

Modern automatic garage door openers often include auto-lock features that engage physical locks once the door is fully closed. This backdrive protection prevents the door from being forced open manually, even if the emergency release is compromised.

For homeowners on the Sunshine Coast looking to upgrade their garage door security with modern locking systems, professional installation ensures these mechanisms integrate properly with your existing door.

Secure the Door Between Garage and Home

The door connecting your garage to your house deserves the same security attention as your front door—arguably more, since it’s often less visible to neighbours.

Replace hollow-core doors with solid-core or metal doors that are much harder to kick in. Install a quality deadbolt with at least a 25mm throw, and reinforce the door frame with a heavy-duty strike plate secured with 75mm screws that penetrate into the wall studs, not just the door frame.

This internal door is your last line of defence if someone gains access to your garage. Treat it accordingly, and always keep it locked when you’re away from home.

Make Your Garage Less Appealing to Thieves

Sometimes the best security measure is simply not advertising what you have.

Hide valuables from view: If your garage door has windows, don’t give thieves a shopping catalogue. Keep expensive items out of sight lines, or store them in locked cabinets.

Garage Windows and Visibility

Garage door windows present a security dilemma—they provide natural light but also visibility for potential thieves. Consider these solutions:

  • Frosted or tinted window panels maintain light while obscuring the view inside
  • Curtains or blinds offer the flexibility to control visibility as needed
  • Reflective window film allows you to see out during the day while preventing people from seeing in

If you’re installing a new garage door, consider whether windows are necessary at all, or position them high enough that they can’t be used to survey your possessions.

Use Lighting, Cameras, and Alarms

Environmental deterrents can prevent break-ins before they happen.

Motion-sensor lighting around your garage and driveway makes it much harder for thieves to work unnoticed. Solar-powered options are affordable and require minimal installation.

Security cameras serve both as deterrents and as evidence collection tools. Position cameras to cover the garage door, side access points, and any windows. Modern systems allow you to monitor your garage remotely via smartphone apps.

Integrate your garage with your home security system if you have one. Door sensors on both the garage door and the internal access door will alert you if they’re opened unexpectedly. 

Modern openers with rolling-code technology offer better protection from the best garage door openers.

Maintain Your Garage Door Regularly

A well-maintained garage door isn’t just about smooth operation—it’s about security. Damaged tracks, broken springs, or malfunctioning openers create vulnerabilities that thieves can exploit. Routine servicing strengthens your door against forced entry — learn what’s included in a garage door tune-up.

Regular servicing catches these issues before they become security risks. Worn rollers or misaligned tracks might prevent your door from closing completely, leaving gaps that can be exploited. A professional inspection can identify and fix these problems before they compromise your security.

The team at Sunshine Coast Garage Door Guys provides comprehensive maintenance services throughout the Sunshine Coast region, ensuring your garage door operates safely and securely. Professional servicing includes checking all locking mechanisms, testing automatic features, and identifying potential security weak points.

Everyday Habits That Reduce Break-In Risk

Everyday Habits That Reduce Break-In Risk

Technology and hardware upgrades are important, but daily habits matter just as much:

  • Always close your garage door when you’re home and when you leave. Many break-ins occur simply because a garage door was left open.
  • Don’t leave remotes in your car, especially vehicles parked outside overnight or in unsecured areas.
  • Be aware of unfamiliar vehicles or people in your neighbourhood, particularly during weekday daytime hours when most break-ins occur.
  • Never advertise that you’re away by leaving your garage door open or announcing travel plans on social media.
  • Get to know your neighbours and maintain good visibility around your property. Thieves prefer targets where they can work unobserved.

Frequently Asked Questions

Can burglars open automatic garage doors?

Yes, burglars can open automatic garage doors using several methods. The most common technique involves exploiting the emergency release cord by “fishing” it through a gap at the top of the door with a coat hanger or wire. Older garage door openers with fixed-code remotes are also vulnerable to code grabbing, where thieves capture and replay your remote’s signal. However, modern garage doors with rolling code technology, proper emergency release protection, and automatic locking features make unauthorized entry significantly more difficult.

Are smart garage door openers safer than traditional remotes?

Smart garage door openers can be safer than traditional remotes, but only when properly configured. They offer advantages like smartphone control with biometric authentication, real-time alerts when your door opens or closes, and the ability to grant temporary access codes that expire. However, they require secure Wi-Fi networks and strong passwords to be effective. The safest option is a modern opener—whether smart or traditional—that uses rolling code technology, which generates a new access code with each use, making code interception virtually impossible.

How do thieves use the emergency release cord to break in?

Thieves exploit the emergency release cord by inserting a thin tool—typically a wire coat hanger—through the gap between the top of the garage door and the frame. They hook the red emergency release cord and pull it, which disengages the automatic opener mechanism. This allows them to manually lift the door from the outside. The entire process takes less than 30 seconds and leaves minimal evidence. You can prevent this by installing a shield around the release mechanism, using a zip-tie to secure the cord when you’re away for extended periods, or upgrading to a garage door that seals tightly against the header.

Should I lock my garage even if it’s attached to my house?

Absolutely. An attached garage is one of the most common entry points for home break-ins, precisely because many homeowners assume the internal door provides adequate protection. Always engage any manual locks on your garage door when you’re away for extended periods, and treat the door between your garage and home with the same security measures as your front door—solid-core construction, quality deadbolt, and reinforced strike plate. Many burglars specifically target attached garages because they provide concealed access to work on the internal door without being seen by neighbours.

How often should I service my garage door for security reasons?

You should have your garage door professionally serviced at least once a year to maintain optimal security. Regular maintenance identifies and addresses issues like worn tracks, loose hardware, malfunctioning automatic locks, and gaps in door seals that could be exploited by thieves. Between professional services, inspect your door monthly—test the automatic opener, check that the door closes completely with no gaps, ensure manual locks engage properly, and verify that motion sensors and security features are working correctly. If you notice any unusual noises, difficulty closing, or visible damage, schedule immediate service rather than waiting for your annual inspection.

Protect Your Home Starting with Your Garage

Securing your garage door from break-ins doesn’t require a complete overhaul or massive investment. Start with the basics—upgrade to a modern opener with rolling code technology, secure your emergency release cord, and ensure the door between your garage and home is solid and properly locked.

From there, layer in additional security measures based on your specific situation, from motion lighting to smart cameras. Regular maintenance keeps everything functioning as it should, while good habits ensure you’re not inadvertently creating opportunities for thieves.
