To Unlock The Door From The Outside
To unlock from the outside you need to add a lock cylinder, installing it so that the spindle is inserted into the flat hole next to the release lever..
Once installed, insert & turn the key of the lock cylinder. This will trigger the release lever, and the bolt should spring open. If the bolt doesn’t automatically spring open , you can use the handle to retract the bolt while holding the key unlocked.
Summary: To lock and unlock from outside, you need three devices: A side lock, a handle for locking, and a lock cylinder for releasing/unlocking.
Use A Zip Tie To Lock The Release Lever
Your garage door opener is connected to an emergency release lever. You can use this lever to open the door manually from the inside when there is a power cut or if the opener has a mechanical problem.
However, burglars can use this lever to access your garage too. By inserting a cloth hanger through the top opening of the garage door, reaching to the lever and pulling it toward the door, an intruder would be able to open the door. This is commonly known as fishing.
Most automatic doors are secure against fishing but it is still possible for a determined burglar to gain access to your garage and home using this method. A simple workaround for this problem is to install a zip tie on the release lever. Heres how to do it:
- Disconnect the garage opener: This important safety precaution will prevent the opener from engaging accidentally and opening the door.
- Identify the release lever cord: This cord is attached to the release lever and prominently swings from the overhead opener trolley i.e. the two horizontal bars that hold the door in the open position.
- Locate a hole at the bottom of the trolley: The release lever is attached to the trolley . Locate the hole on this hinge as well.
- Insert the zip tie: Insert one end of the zip tie through the hole in the hinge and then through the hole on the release lever. This will give you a loop around the two holes. Tighten the zip tie and trim off the excess tie using a wire cutter.
Securing The Door From The Outside
You can secure your garage door with a lock accessible from the outside, which is a great way to remind yourself to unlock the door before using the opener. There are two common ways to lock your garage door from the outside:
- A sliding bar lock with an L-handle or T-handle, which is installed as a component of the door
- A garage door defender , which is a separate locking mechanism that gets bolted to the ground

Use A Door Defender To Secure Your Garage From The Outside
A garage door defender is a pretty simple device that secures your garage door from the outside.
How does it work?
It consists of two main parts: the steel base plate and the door lock itself. To make it work, first, you have to fix the base plate to the ground in front of the garage door using the included bolts.
After bolting down the base plate, you have to secure the defender on top of it with a padlock to lock the door. I suggest that you opt for a model that comes with a padlock so you dont have to buy one separately.
The obvious advantage of a garage door defender over other types of lock is that it is surface mounted, so you dont have to drill holes into your garage door . Therefore if you decide to remove it later, its much easier to do so.
Another benefit is that it also serves as a great visual deterrent.
FYI Garage door defenders only work on up and over garage doors . So you cant use it to secure a sectional garage door.
While its true that a door defender will allow thieves to peel the side of the garage door open but thats pretty time-consuming and makes a lot of noise, so only a really determined burglar will try this.
Thus, if you have an up and over garage door, its still one of the best ways to securely lock it from the outside.
As an alternative, you can use a simple latch that can be secured with a padlock. The latch should be mounted on the door so that when its extended it goes directly into the ground .
Can You Change The Garage Door Lock
Yes, you can change your garage door lock. If you have a mechanical lock, you can change it out yourself, or you can call a locksmith to rekey the existing lock.
If you have an installed garage door opener, youll likely need professional help to install a new one. Alternatively, you can add something like the Garage Shield or Garage Defender to further secure your garage without any help at all.

Can You Really Benefit From Adding An External Lock To Your Automatic Garage Door

Although you can use a protective garage shield to prevent the above-mentioned scenario, its still reasonable to reinforce the door .
FYI If your garage has any windows, do not miss this article where I discuss 5 simple methods you can use to make them burglar-proof.
Keep in mind that if the installed lock is not synced with your door opener, you must always manually open the added lock first to avoid damage.
How Do You Replace A Garage Door Lock Bar
Replacing or installing a lock bar on a garage door is relatively simple. A lock bar can sit on the interior or exterior of the garage, so begin by deciding where youll place it. For these instructions, well focus on interior installation since thats more popular. Then, close the garage door and unplug the power source if you have an electric door.
After that, grab your garage door lock bar kit. These kits should come with everything you need for installation, including bolts and screws. There should also be instructions with diagrams in case you get confused. If youve bought the sliding door lock on its own, youll also need to invest in #14 ¾ screws for installation.
Start by removing the old lock bar by taking out the existing bolts. Many garages will have a lock bar on either side, so make sure you remove both!
Youll want to install the new sliding lock bar in the second to the bottom panel of the garage door. This will allow you to lock the door while slightly lifted, which is ideal if you ever need ventilation.
Installation is usually as simple as bolting the lock bar in place. Just line the lock body up with a railing slot so that the bolt will extend through the slots middle. Make sure you place the lock body slightly inward towards the garage door so that the bolt doesnt hit the rail when its drawn.
Ideally, youll place a sliding lock bar on either side of your garage door. Doing so will give you the most security when it comes to intruders.

You can also install sliding bar locks on either side of the garage door. You probably wont want to use the bar locks on a daily basis, as theyre a bit inconvenient, but theyre ideal if youre going out of town.

T-handle types are the most common locking mechanism for metal garage doors. Many of them will come pre-installed with these locks. Users can typically expect t-handle locks to use a spring-latch cable connected onto the lock handle, helping to open your garage door.
