Importance of Garage Security

Garage security is an important aspect of overall home security. Often times, garages are used not only for parking vehicles, but also as storage areas for tools and other valuable items. This makes them attractive targets for burglars and thieves.

Furthermore, the garage door serves as a point of entry to the house itself, providing easy access to potential intruders. Therefore, it is crucial to ensure that your garage is properly secured.

In addition to installing a high-quality garage door and using strong locks, regular maintenance of your garage lock is also essential. This not only helps prevent break-ins, but also extends the lifespan of your lock.

Types of Garage Locks

There are several types of locks that can be used on a garage door. The most common ones include:

  1. Deadbolts – These are the most secure type of locks and are commonly used on entry doors. They can also be installed on garage doors for added security.
  2. T-handle locks – These locks are typically used on overhead garage doors and have a T-shaped handle that is turned to lock or unlock the door.
  3. Slide bolts – This type of lock is installed on the inside of the garage door and can be manually slid into place to secure the door.
  4. Electronic keypads – These locks use a combination code or fingerprint technology for entry, providing added convenience and security.

10 Methods How to Change a Garage Lock

1. Rekey the Lock

Rekeying a garage lock is one of the easiest ways to change it. This process involves removing the lock cylinder from the door and replacing the pins with new ones that match a new key. It’s relatively simple and can be done without having to replace the entire lock.

2. Install a New Lock

Installing a new lock is more involved than rekeying but can still be done by most homeowners. This method requires removing all of the old hardware from the door, including any strike plates, and then installing a new deadbolt or knob set on the door. This method will require some basic tools such as a drill, screwdriver, and level.

3. Change Out Cylinder

Changing out just the cylinder in a garage lock is another easy way to change it without having to replace the entire lock. To do this, you’ll need to remove the screws that are holding the cylinder in place and then unscrew it from its housing. Once you have removed it, you can install a new one with matching keys for your new keyed entry system.

4. Add an Electronic Deadbolt

Adding an electronic deadbolt is an increasingly popular option for changing out garage locks as they offer added security and convenience features such as remote access and automated locking/unlocking functions via smartphone apps or voice commands.

Installing an electronic deadbolt does require some additional wiring work so it’s best to consult with an electrician if you’re unsure how to proceed with this method of changing your garage locks.

5. Install Keyless Entry System

Installing a keyless entry system is another great way to upgrade your existing garage locks without having to replace them entirely. Keyless entry systems allow you to enter your home using either a code or biometric reader such as fingerprint or facial recognition technology instead of needing physical keys for access.

These systems are becoming increasingly popular due to their added security benefits and ease of use compared to traditional keyed locksets.

6. Replace Existing Lockset

Replacing an existing lockset is another straightforward way of changing out your garage lock without having to replace the entire unit itself. To do this, you’ll need to remove all of the screws that are holding your old lockset in place before unscrewing it from its housing and then installing your new one in its place using matching screws for secure installation. 

7. Use Smart Lock Technology

Smart lock technology provides homeowners with yet another option for upgrading their existing garage locks without having to replace them entirely. Smart locks offer advanced features such as remote access via mobile app, automated locking/unlocking functions, voice commands, and even geofencing capabilities which allow users to set up automatic locking/unlocking based on their location.

8. Install Magnetic Locks

Magnetic locks provide homeowners with yet another option for upgrading their existing garage locks without having to replace them entirely. Magnetic locks use magnets instead of mechanical components like traditional door hardware, making them much quieter when operated.

Additionally, magnetic locks are also easier to install since they don’t require any drilling or cutting into existing door frames as traditional mechanical locksets do. 

9. Upgrade Existing Hardware

Upgrading existing hardware is another great way of changing out your garage lock without replacing it entirely. This involves replacing parts such as strike plates, hinges, handles, knobs, etc.,

which can help give your current setup a fresh look while also providing improved security benefits over time. Additionally, upgrading existing hardware also allows you to maintain compatibility with other components such as deadbolts or alarm systems that may already be installed on your door. 

10. Use Professional Installation Services

If none of these methods seem feasible for changing out your garage lock, then hiring professional installation services may be worth considering. Professional services will have access to specialized tools and expertise needed for more complex tasks, such as wiring work associated with electronic deadbolts or keyless entry systems.

They will also be able to advise on which type of setup would best suit your needs based on factors such as budget, security requirements, etc.

Things to Consider When Changing Your Garage Lock

Changing your garage lock may seem like an easy task, but there are a few important things to consider before you dive in. In this section, we’ll discuss some key points that you should keep in mind when changing your garage lock.

Firstly, it’s important to assess the condition of your current lock before making any changes. Is it still functioning properly or does it need to be replaced? If your lock is damaged or outdated, it’s best to replace it entirely rather than trying to fix it. This will ensure the security of your garage and prevent any potential issues down the road.

Important to Assess the Condition of Your Current Lock

Next, you should consider what type of lock you want to install. There are a variety of options available such as deadbolts, keyless locks, and smart locks. Each type has its own unique features and benefits, so it’s important to do some research and determine which one best fits your needs.

Another factor to consider is the level of security you require for your garage. If you keep valuable items in your garage or have a connecting door between your garage and home, you may want to invest in a higher security lock. On the other hand, if your garage is used mainly for storage and doesn’t contain anything of significant value, a basic lock may suffice.

You should also take into account the compatibility of your chosen lock with your existing garage door or handle. Some locks may require specific mounting hardware or drilling, so it’s important to check beforehand to avoid any complications during installation.

In addition, you should consider the weather and climate in your area. If you live in an area prone to extreme temperatures or heavy rain, it’s important to choose a lock that can withstand these conditions. Look for locks with weather-resistant materials or ones specifically designed for outdoor use.


Although changing a garage door lock is a complicated process, it does not have to be an insurmountable burden. If done correctly, it can increase your security and give you peace of mind knowing that your family and property are safe. Therefore, taking the time to learn how to change a garage lock is something to consider if your current system is outdated or unsafe.

With this guide behind you, the necessary steps will become second nature and the process won’t seem so daunting after completing these steps multiple times.
