If your garage door is easy to open from the outside, it’s not just an inconvenience — it’s a security risk. At Overhead Door Company of Puget Sound, we know how important it is to keep your home and belongings safe. That’s why having the right garage door lock is a big deal.
In this guide, we’ll cover everything you need to know about garage door locks — the types, the benefits, and how to choose the right one for your setup. Plus, we’ll offer real-world tips to help keep your garage secure year-round.
Why Garage Door Locks Matter
Your garage is more than just a place to park your car. It might hold tools, bikes, lawn equipment, sports gear, and even act as a side entrance to your home. A secure lock helps protect all of that. Here’s why people upgrade or add locks:
- Extra protection against theft and break-ins
- Peace of mind while traveling or on vacation
- Insurance requirements for detached or vulnerable garages
- Preventing unauthorized access (especially in multi-unit buildings)
- Enhanced safety for garages used as workspaces or storage
If your garage door doesn’t lock properly, you’re basically leaving a welcome mat out for trouble. And since many garage doors connect directly to the home, it’s even more important to secure them right.
Types of Garage Door Locks
Let’s take a look at the most common types of garage door locks and how they work:
1. T-Handle Locks
These classic locks are common on older or manually operated garage doors. The T-handle on the outside is turned with a key, and it operates an internal latch mechanism that secures the door.
Best for: Manual or detached garages
Pros: Affordable, widely available, easy to replace
Cons: Can be picked or forced open with the right tools
2. Slide Bolt Locks (Latch Locks)
Also called barrel bolts, these slide a metal rod into a receiver mounted to the garage door track. They’re usually mounted on the inside and used in addition to an opener.
Best for: Supplementing electric garage door openers
Pros: Inexpensive, adds physical security
Cons: Not accessible from outside, can’t be used remotely
3. Deadbolt Locks
Just like your home’s front door, deadbolt locks offer heavy-duty protection. These are usually used on the door between the garage and the house or for side-entry garage doors.
Best for: Homeowners looking for stronger physical protection
Pros: Very secure, can be rekeyed, long-lasting
Cons: May require cutting into the door or frame to install
4. Smart Locks / Keyless Entry Systems
These use digital keypads, Wi-Fi, or Bluetooth to allow entry via codes or smartphone apps. Many even log access times, which is great for keeping track of who comes and goes.
Best for: Modern homes, families, rental properties
Pros: Keyless convenience, real-time control, guest codes
Cons: Higher cost, requires power and/or battery backup
5. Automatic Garage Door Opener Locks
Some garage door openers come with a built-in auto-lock feature. This engages a bolt or bar into the rail track whenever the door fully closes.
Best for: Smart garage systems
Pros: Built-in security, no need for extra hardware
Cons: Only compatible with newer models of openers
How to Choose the Right Garage Door Lock
Picking the best lock starts with understanding your specific needs. Here’s what to think about:
1. Garage Type
Attached Garage: These often lead straight into your home, so stronger locks like deadbolts or smart locks are best.
Detached Garage: A T-handle lock or additional slide bolt is smart here, especially for standalone buildings.
2. Door Type
Manual Doors: Use locks like T-handles or latch bolts.
Automatic Doors: Look for slide bolts that don’t interfere with openers or built-in locking systems.
3. Daily Use
If you enter and exit your garage several times a day, smart locks or keypads may be more convenient.
For garages used mostly for storage, a manual lock might be enough.
4. Security Needs
Live in a high-crime area? Go for reinforced deadbolts or smart locks with tamper alerts.
Want convenience over complexity? A simple bolt may do just fine.
How to Install a Garage Door Lock
Some locks can be a DIY project, while others might need professional help. Here’s what to consider:
- T-Handle Locks: Usually easy to install with a drill and screwdriver.
- Slide Bolts: Attach with screws and take just a few minutes.
- Deadbolts: Often require a chisel or specialized tools for a clean fit.
- Smart Locks: Installation varies — some are simple, while others require wiring or Wi-Fi setup.

Boost Garage Security With These Extras
A lock is a great first step, but don’t stop there. Combine your garage door lock with other tools for even more peace of mind:
- Security Cameras: Watch your garage from anywhere.
- Motion Lights: Keep the area bright when someone approaches.
- Window Covers: Stop prying eyes from seeing inside.
- Garage Door Timers: Automatically close your garage if you forget.
- Reinforced Door Panels: Strengthen your door against forceful entry.
It all adds up to a safer home.
Signs You Need a New Garage Door Lock
Not sure if it’s time to upgrade? Here are some red flags:
- Your key sticks or doesn’t turn easily
- The lock feels loose or flimsy
- You’ve lost the keys and never changed the lock
- The lock is rusty or damaged
- You’ve recently had a break-in or security scare
What is the best type of lock for a garage door?
The best type of lock depends on your garage door. For automatic doors, a smart lock or an automatic opener lock is ideal. For manual doors, T-handle locks and slide bolts offer solid security.
How do I stop someone from opening my garage door?
You can stop break-ins by adding a slide bolt lock, unplugging your opener when away, using zip ties on the emergency release, and adding motion sensor lighting or a smart garage system.
How do I burglar proof my garage?
Use reinforced locks, install security cameras, cover windows, and add lights with motion sensors. Make sure the emergency release can’t be accessed from outside.
Can you put a lock on a garage door?
Yes. T-handle locks, deadbolts, and slide bolts are all options. Just make sure they’re compatible with your garage door style and opener system.
