Tools and materials you need
Before you start the garage door handle replacement, you should gather the following tools and materials:
- Screwdriver
- Hand drill
- Measuring tape
- Pencil
- Pliers
- Wrench (as needed)
- Safety glasses
- Safety gloves
- Replacement garage door handle
Choosing the right garage door handle replacement
Most garage door handles use a T-handle lock, which comes in different handle base thicknesses. It also comes in various materials, a locking mechanism, and compatibility.
To make sure you’ll get the correct replacement for your T-handle garage door handle lock, you should check the following:
Size
Using a tape measure or ruler, check the full length of the handle, width from top to bottom, and how far the handle sticks out from the door (projection). You should also check the distance between screw holes, center to center.
Once you have the measurements, see which replacement size you need from this table:
Garage door handle features | Typical size range |
Handle length | 100 mm to 150 mm |
Handle width | 75 mm to 100 mm |
Projection | 25 mm to 50 mm |
Screw hole diameter | 3 mm to 5 mm |
Door thickness | 25 mm to 45 mm |
Lock cylinder length | 38 mm to 63 mm |
Material
If you’re on a budget, you can get heavy-duty plastic T-handles. For durability, we recommend choosing stainless steel or other metals with corrosion-resistant finishes.
Locking mechanism
Next, you need to identify the type of lock you currently have. It can be a deadbolt, camlock, slide bolt lock, latch lock, or keyed lock.
Make sure that the handle replacement has the same lock as the damaged one. Check if the rods, latch, and locking bar align with your current handle’s mechanism.
By getting the exact locking mechanism, you no longer have to do further modifications on your garage door.
Mounting hardware
Check if the replacement set has complete hardware, including screws, mounting brackets, and garage door handle cover plate.
Safety precautions before you start
Before you start the garage door handle installation, you should keep the following safety tips in mind:
- Disconnect the door from the opener. Pull the emergency release cord to disconnect your garage door from the automatic opener. This prevents accidental operation while you’re working on your door.
- Wear protective gear. Make sure you put on safety glasses to protect your eyes from debris that may become airborne during installation. You should also wear gloves to avoid nicks and cuts.
- Keep children and pets away. Always keep kids and pets away to avoid accidents, especially when using power tools like an electric drill.
- Have a helper if possible. It’s best to have someone assist you in holding the lock outside while you put all the other parts inside the garage.
Step-by-step guide to replace a garage door handle
With all the necessary materials and safety precautions, you can follow these steps to replace your broken garage door handle:
Step 1. Remove the broken handle
Locate the screws of the old handle of your garage door and use a screwdriver or hand drill to remove them.
Start from the handle inside your door. Once you’ve removed all the fasteners, wiggle the old handle off the door until it comes off. You should also remove the external handle and lock on the other side.
Step 2. Inspect the locking components
Check if there’s rust or any damage on the mounting holes before you install the replacement handle. You should also clean the area with a cloth to remove any debris that could get in the way of the new installation.
While you’re at it, lubricate the existing lock’s rods, latch, and cylinder.
Step 3. Prepare the new handle
See if your new handle is compatible with the old one. To do this, check if the mounting holes align and the locking mechanism of your current lock matches the new handle.
Step 4. Secure the handle to the door
Once you’ve confirmed the compatibility of your new garage door handle, position the handle on the garage door and align its mounting holes accurately.
After that, go back inside your garage to insert all the screws or bolts and tighten them with a drill. It will be easier if someone holds the external handle for you to install the screws on the other side of the door.
PRO TIP: Don’t over-tighten the screws just yet – in case the next step doesn’t work, you may need to remove the handle and reinstall it.
Step 5. Test the new garage door handle
Once you’ve installed the new handle, test if the lock will engage and if you can open or close your door properly. See if the lock will feel sticky, if the handle will make unusual noises, or if it’s too loose.
Troubleshooting garage door handle problems after replacement
Replacing a garage door handle with a lock is fairly simple, but in case you encounter some issues, here are some troubleshooting steps you can do:
1. The door handle screws won’t tighten.
In some cases, the door handle screws feel loose or won’t ‘bite’. It’s possible that the screw holes have become larger from the previous installation, or your screws are stripped.
For loose screw holes, you can fill them with a wood filler, epoxy, or a plastic anchor. After that, re-drill the screw and see if it will become tight.
If the problem is stripped screws, you can replace it with longer or larger ones that match your door’s thickness.
2. The locking mechanism won’t work after installing the new handle.
If the garage door lock won’t engage after replacing the handle, it’s possible that the cylinder or calm isn’t aligned properly with the internal latch or bar. It’s also possible that your new garage door handle isn’t compatible with your current lock component.
To fix this problem, remove the handle and re-align the lock mechanism inside. Make sure that all the rods or linkages are properly installed to avoid any sticking or jamming.
However, if the handle is incompatible, you can get a new one or replace the entire lock mechanism.
3. The handle key won’t insert or turn.
If the lock key won’t go in or turn fully, the cylinder inside could be misaligned or jammed. It’s also possible that dirt or rust have accumulated inside the cylinder.
For this, you can try cleaning the lock cylinder and see if the key will fit just right. If this doesn’t solve the problem, you may need to replace the cylinder in case it’s already broken.
4. The garage door handle is wobbly or loose after installation.
A loose or wobbly garage door handle means that you haven’t tightened the fasteners properly. Also, there might be something wrong with your installation, which prevents the handle from fitting snugly on the door.
First, check if the handle is seated flush against the door’s surface. Next, check your screws and its holes to see if you need to use plastic anchors or epoxy to tighten the grip.
5. The new garage door handle makes unusual noises.
Any rattling, grinding, or grating noise coming from your new garage door handle indicates poor installation. It’s possible that you failed to align the locking mechanism correctly or that some of the screws are loose.
To fix the problem, double-check the lock and adjust its alignment as necessary. You should also apply a silicone-based lubricant to reduce friction on the lock.
Lastly, tighten all screws and test if this solves the noise problem.
6. The door jams after installing the new handle.
If your garage door jams after installing a new handle, you should check for any obstruction, such as the lock sticking or the handle protruding too far.
For this, you may re-adjust the installation or get a handle with a shorter projection, so it doesn’t get caught on the door frame.
