Garage Door Security (Best Locks Guide, How to Install)
This post contains affiliate links.
The garage door is usually the weakest link in your garage and home security. Securing the garage door is essential to protect everything you have in your garage and inside the house, including you and your family. If the garage is attached, it can also be an entry point to the whole house.
Beef up garage door security with manual deadlocks, deadbolts, automatic electric locks, emergency release handle shields, garage defenders, smart door controllers, and security cameras.
In this article, we look at how break-ins usually happen. How to make your garage door more secure with additional locks. How to install garage door locks and prevent someone from remotely opening the door.
How Do Thieves Break Into Garages?
Garage break-ins usually happen with the well-known “fishing method” that works with unprotected sectional doors (the most popular type of residential garage door).
The break-in method works by using the top of the garage door to gain access to the emergency release cord. The burglar bends the top of the door with a stake, uses a hooked wire through the opening, and pulls the emergency release cord. This disconnects the garage door opener from the garage door so the door can be opened manually. Watch the video below to get the idea.
(Zip tie is not a good idea in case of emergency)
Other breaking-in methods are more traditional, using the crowbar in leverage points like under the door or side of the door and drilling or cutting the locks. But these are noisy and surely easy to notice by passers-by.
How to Make Garage Door More Secure With Inside, Outside Locks
Garage doors can be made more secure by adding mechanical locks that prevent opening the garage door. These can be manual or automated and electric. They can be installed inside or outside the garage door.
Suppose you use the garage door daily to park your car etc. In that case, it is recommended to get an automatic lock for your convenience.
This also prevents you from forgetting to disengage manual locks and prevents the garage door opener from breaking down. Which can happen if a manual lock is engaged and the motor does not have an automatic overload cutoff.
Manual locks have their uses also. Especially if you are going away for a while, the manual locks effectively prevent break-ins. They can also be used daily if you don’t want or need automatic locks.

How to Lock or Open Garage Door From Inside Without Power
Can Someone Else Remote Open My Garage Door
You may be wondering if someone else can gain access to your garage by remote opening the door.
Garage door openers can be hacked. It is possible but very unlikely. Especially older openers that use fixed codes. Newer ones use rolling codes and are very secure. Smart garage door openers can be hacked through your home WiFi if it is poorly secured. Again very unlikely to happen.
Let’s see how it may be possible for someone to gain access to your garage by remote.
What Is a Fixed Code Garage Door Opener?
Old garage door openers and remotes use a fixed code that uses RF(radio frequency) to communicate. When you press the remote button, it sends a code to the garage door opener to open the door. The problem is that the code never changes and is something like 1234. These old garage door openers are very insecure and badly outdated. It’s best to get a new opener.
How to Check if Your Garage Door Opener Uses a Fixed Code?
Check your clicker/fob/remote. If it says:
- security+
- security+ 2.0
- rolling code
- Intellicode
- CodeDodger
Or something similar, your device does not use a fixed code, and your garage is way more secure than the old garage door openers.
If your clicker/fob/remote does not say anything of the sort, you have to first check the device manual or documentation. If you have none, check the manufacturer and model from the garage door opener (there should be a sticker or plate on the unit). Then do some research online or call the manufacturer.

Dates | System | Color of programming button and LED on unit | Color of LED on remote |
---|---|---|---|
1984–1993 | 8-12 DIP switch on 300-400 MHz | white, gray, or yellow button with red LED | red |
1993–1997 | Billion Code on 390 MHz | green button with green or red LED | green |
1997–2005 | Security+ (rolling code) on 390 MHz | orange or red button with amber LED | amber or none |
2005–present | Security+ (rolling code) on 315 MHz | purple button with amber LED | none |
2011–present | Security+ 2.0 (rolling code) on 310, 315, and 390 MHz | yellow button with amber LED and yellow antenna wires | red or blue |
Overhead Door Corporation and The Genie Company
Dates | System |
---|---|
1985–1995 | 9–12 DIP switch on 360, 380, or 390 MHz |
1995–2005 | Intellicode/CodeDodger (rolling code) on 390 MHz |
2005–present | Intellicode/CodeDodger (rolling code) on 315 MHz |
2011–present | Intellicode 2/CodeDodger 2 (rolling code) on 315 and 390 MHz |
So if your garage door opener is manufactured before 1995/2005, when the rolling code became available. it’s best to check if it has modern security features.
What Is a Rolling Code Garage Door Opener?
Rolling or hopping codes offer much more security with trillions of combinations that change every time the garage remote is used. The opener and the remote use a random number generator to pick a new code which is stored and synchronized only for that time. All manufacturers use different systems, and it’s all very technical.
You can read all about garage door remotes in this article.
Can Rolling Codes Be Defeated?
Rolling codes can be defeated with rolljam devices(wikipedia), but this is extremely unlikely to happen in real life.
What Frequency Do Garage Door Openers Use?
Garage door openers usually use frequencies between 300 – 400 MHz.
What Is a Code Grabber?
Code grabbers are used to recording codes transmitted through radio frequencies. The device must be somewhere near the devices using radio frequencies to work.
Let’s say there is a code grabber near your garage door opener. When you come home and push the remote button to open the garage door, the code grapper then snatches the code between the remote and the opener.
The burglar then comes by later and uses the code grapper to gain access to the garage.
Code grabbers can also be used to grab codes between car and remote car keys.
Luckily, this method only works for very old cars, and garage door openers and newer devices and vehicles are safe.
