Is your garage really as secure as you think? Many homeowners unknowingly make critical garage security mistakes that leave their property vulnerable.
In this guide, we’ll uncover the top 5 garage security flaws most people miss—and how to fix them before it’s too late.
5 Common Garage Security Mistakes
Here’s a detailed look at 5 security flaws of garages that most people overlook, along with why each one matters:
1. Weak or Outdated Side Doors and Access Points

Why It’s a Problem
Side doors or rear doors on garages are typically used less often than the front-facing main entrance.
Because of this, they are often installed with minimal security features—think standard doorknobs, old hinges, and no deadbolts.
These entry points are typically out of sight from neighbors or street view, making them a prime target for burglars who want to break in quietly and quickly.
What You Should Do
Upgrade any secondary garage entry doors to solid-core or steel models. Make sure to install high-quality deadbolts and reinforce the door frame with a metal strike plate.
If the door has glass panels, replace them with impact-resistant glass or apply security film to prevent easy breakage.
For an added layer of protection, consider a smart lock system that can be monitored and controlled remotely.
2. No Integrated Garage Alarm or Motion Sensors
Why It’s a Problem
Even homeowners with advanced security systems often exclude their garage from full monitoring. This oversight creates a major blind spot that criminals can exploit.
A garage that lacks contact sensors, motion detectors, or security cameras can be broken into without triggering any alarms, giving burglars unrestricted access to your home.
What You Should Do
Incorporate your garage into your home security network. Add contact sensors to every door and window, install motion detectors, and mount a smart camera that can send real-time alerts to your phone.
Many modern security systems allow seamless integration with garage doors, so you can track open/close activity from anywhere.

3. Exposed Emergency Release Cord

Why It’s a Problem
Modern garage doors come with an emergency release feature—a red cord that disengages the garage door motor during a power outage.
Unfortunately, this safety mechanism can also be a serious security vulnerability.
Thieves know how to “fish” this cord using a wire hanger through the top gap in the garage door, allowing them to disengage the opener and lift the door manually in seconds.
What You Should Do
Install a garage door emergency release shield, which prevents tools or wires from reaching the cord from outside.
Alternatively, you can secure the release cord with a zip tie or position it in a way that it can’t be pulled from outside.
Just ensure that it still functions in an actual emergency. Adding a motion sensor camera above the garage door is another layer of security that can deter intruders.
4. Unsecured or Visible Garage Windows

Why It’s a Problem
Garage windows may let in natural light, but they also let intruders see inside. Burglars often “window shop” before breaking in.
If they spot valuable items—like bikes, tools, or even a door leading into your house—your home instantly becomes a target.
Worse, these windows are often not reinforced, making them a weak point for physical entry.
What You Should Do
Apply privacy film or install frosted glass to obscure the view from outside.
For added security, use polycarbonate security panels or bars over the windows without making it look too industrial.
Consider placing motion-activated lights near the windows to discourage anyone from getting too close after dark.
5. Weak or Unlocked Door Between Garage and House

Why It’s a Problem
The door that connects the garage to your home interior is often treated like an interior door—frequently unlocked, and sometimes made from lightweight materials with only a standard lock.
However, if someone breaks into the garage, this door is often the last barrier protecting your home and family.
What You Should Do
Upgrade this door just like you would a front or back entrance. Use a solid-core or metal door, install a heavy-duty deadbolt, and reinforce the door frame with a security strike plate.
For extra peace of mind, install a smart lock or keypad entry system that lets you monitor and control access remotely.
Final Thoughts
In conclusion, ignoring garage security can put your entire home at risk. By spotting and fixing these common garage security mistakes, you can strengthen one of the most overlooked entry points to your property.
From outdated locks to overlooked entryways, addressing these flaws helps protect your belongings and boosts overall home safety. Don’t let simple garage security mistakes compromise your peace of mind—secure your garage the right way today.
