We often get garage door service calls from customers who have door remotes that have stopped working. They generally assume that the garage door remote is broken, and that a new unit is the only option.
In most cases, a garage door opener that’s not working is nothing more than a dead battery. But maybe you’ve replaced the battery in your remote and it is still not working. Not to worry, we may be able to save that old remote yet. Today’s post covers everything you need to know for replacing a garage door opener battery and other tips to try for getting a remote back online.
How Your Garage Door Opener Remote Works
Pushing your garage door remote sends a signal from the transmitter in the remote to the receiver located in the garage motor’s housing. This is done by radio transmission over a specific frequency. The signal is sent with a code that’s needed in order to complete the function of opening or closing your garage door. If the receiver doesn’t get the right code, it’s not going to work. This is done for security because if it didn’t require an encoded transmission, a single garage door remote may be able to open a slew of other doors.
When the garage door remote’s battery is failing or has failed, the transmitter is not able to send a strong enough encoded signal to the receiver. If you’ve replaced the battery and the remote is still not working, there may still be hope by reprogramming the remote. We’ll provide a quick tutorial on this process later on in the post
Checking the Batteries on a Garage Door Remote
If you carefully remove the back cover of your remote, you will see the battery inside the housing. There are several battery variations. The most common battery type that we encounter is what looks like a standard watch battery. These batteries usually have their type printed on top making getting a replacement easy. Replacement batteries are widely available online or just about any major retailer.
The next most common battery that you will find in these applications is a standard 9-volt battery. These batteries are also widely available online or through major retailers. Slightly less common batteries our technicians encounter are very small alkaline batteries. These can be a little harder to find but any battery store should be able to help you find a suitable replacement.
Garage Door Remotes 101: How to Replace Garage Door Opener Battery
When you know the right-sized battery for your garage door opener remote, the process of replacement is fairly straightforward. Follow the steps below to replace your garage door opener battery.
Locate the Battery Compartment Turn the garage door remote over and open the remote’s battery compartment usually by just sliding down on the cover. Sometimes you’ll need to pull the sun-visor clip out first. If so, just slide the clip down and out and then you can access the battery compartment. You may also have a clicker that screws together with very small screws like what you’d find in a pair of eyeglasses. Another variation is one which simply snaps together and can be pulled apart.
Take Out the Old Battery Once you have access to the battery compartment, carefully remove the old battery and set it aside. Most single-use batteries are deemed non-hazardous and okay to toss with your household trash. Just always make sure you follow your local ordinances for properly disposing of batteries.
Clean the Compartment Brush any corrosion away from the terminal leads and give it a quick wipe with a clean cloth. If you have compressed air, you can use this to blow away any dust or other accumulations from the battery compartment.
Replace the Battery Insert the new battery and make sure it’s snugly in place but don’t be too forceful as the remote’s housing can be delicate.
Slide the Battery Cover Back on the Unit Replace the battery cover by reversing whatever process was used to open it. Remember to be careful with the small plastic components as even a little too much force can snap the tabs that allow the battery unit to slide back together.
Reprogramming a Garage Door Opener Remote
Homeowners often miss the most important step to getting their remotes up and running again after replacing the battery. For security purposes, whenever the garage door remote’s battery has died, the remote will need to be reprogrammed to the garage door opener. When you remove the battery from a remote, or the remote goes dead, it loses its secure connection to the garage door opener. You may also have a situation where one remote goes missing and you’d like to reset the opener’s code. In either case, reprogramming your remote will create a new, secure signal from your transmitter to the receiver.
Reprogramming a garage door remote can be a little different depending on the model of your opener. If you still have it or by searching online, pull up the manual for your garage door opener and find the section on remote programming. For newer models, this process can be very easy since they usually have a single “learn” button on the side for pairing the remote back to the opener. Older units can be a little more involved with the use of switches to accomplish reprogramming the coded signal.
When a Garage Door Goes Bad
Time and the elements take their tolls on your remote just like everything else, and sometimes a defective unit does make it past quality assurance testers. If your garage door opener is relatively new, your remote may still be under warranty and a new unit can be sent by the manufacturer. Otherwise, you’ll need to search for a replacement opener.
Whenever you search for a replacement it’s best to get one made by your unit’s manufacturer rather than a universal. Working in the industry for decades, we’ve come to rely on reputable manufacturers like LiftMaster for high-quality products homeowners can rely on.
