How to Fix a Garage Door Remote That Is Not Working

Garage door remotes make accessing your garage door easy, and when a remote fails (stops working), this can lead not only to frustration for you but also to security concerns. Most of the time, remote malfunctions are an indicator that something is wrong. Fortunately, in most cases, remote failure has to do with a simple problem, such as having a dead battery, having sensors that are misaligned, needing to re-program your remote, or malfunctioning electronic parts due to normal wear. This guide covers some of the most typical reasons for remotes failing, steps you can take to troubleshoot the problem, and when to call an expert to help.

Common Causes of Garage Door Remote Failure

1.Dead battery

A dead or dying battery is the number one issue. Replacing the battery will restore the remote functionality immediately.

2.  Lost sync

If the opener lost power or lost memory, this could result in remote programming being gone as well. Use the opener's "Learn" button to sync the remote back to your opener as indicated in the manufacturer's manual.

3. Power or wiring problems

Ensure the opener is plugged in and has power. If your garage door opener is unplugged or the power is down due to some other reason, both the wall control for your garage door and your remote will not work.

4. Safety sensors or lock

The safety sensors (photo eyes) on your garage door opener must be aligned and kept free of obstructions. Ensure the lock-out switch located on your wall console is off (if the lock-out switch is pushed in, the remote will not work).

5. Interference

The signal from the remote can be jammed by other electronics located nearby and/or strong radio signals. For example, in the past, strong military or emergency radio signals have prevented garage door opener signals from operating as intended, with users having to stand much closer to their garage door to get their remote to work. Interference can greatly reduce the range of the remote and may prevent the remote from working at all.

6. Defective remote/receiver

Over time, the transmitter in the remote, as well as the receiver in the opener can become defective. A physical or normal wear and tearVerify the power of the opener by checking any indicator lights and/or the wall panel. If the wall button does not work, then that indicates an issue with the door or the opener itself; you will need to troubleshoot further to find out why the wall button does not work.

Step-by-Step Troubleshooting Guide

If you have tried all the steps above, put in a new battery for the remote. Doing so solves most problems.

If the battery does not resolve the issue, try reprogramming the remote. Consult your owner’s manual for how to perform this step and to locate the Learn/Program button on the opener that you will use to Re-sync the remote.

Testing the range of the remote can help determine if there is interference that results in the remote not working. Stand back from the door a few feet and press the remote button. If the remote works, you are out of the range. However, should the remote staple work only at a very short distance, there may be external interference or obstructions blocking the radio wave signal. Remove any obvious physical obstacles (vehicles, metal objects) and test the remote while continuing to stay out of the way of any anything potentially blocking the radio signal.

You should check the safety sensors to make sure they are all level and not obstructed before testing again. The lock switch on your wall will disable the opener and remote controls.

If possible, try a second remote or keypad. If this alternative device works, then the original remote is likely defective. If the replacement doesn’t work, the opener will be at fault.

If none of the devices work correctly, check to see if your neighbors have the same issue, or it could be a coincidence that when you check the opener under different conditions, it works. If you have ruled out all of the other possibilities, consider contacting the manufacturer of the opener or an installer for their assistance. Sometimes, the manufacturer has a replacement radio receiver and remote control set available that operate on a frequency that won’t be impacted by your situation.If none of these measures have solved the issue with your garage door opener or if the door behaves in a dangerous manner (such as failing to reverse when it senses an object in its path), you will need to consult an experienced garage door professional.

When to Call a Professional

There are some circumstances in which a qualified technician should be consulted. For example, if neither the wall switch nor either remote control is able to open the garage door (provided there is power present), the issue is most likely with the motor or electronics of the garage door opener. Additionally, if the garage door hangs up on the track, will not fully close, or fails the safety-reversal test, stop using the door immediately and seek service.

Complex or ongoing problems that are persistent or complicated (such as having no working remote or having continued interference) also require assistance from an expert. The technician can identify the reason causing the problem and replace any components as required.

FAQ

 Why did the remote stop working after the battery was replaced?

 First, you should attempt to re-program the remote by utilizing the Learn button located on the garage door opener unit. You should confirm that the garage door opener has power and that the safety sensors on the garage door are also clear. If you still have a second remote and/or keypad available to you, you can use the second remote or keypad to verify that your original remote is in fact no longer functioning. If your opener still does not work, it may require service.

How often should I check my garage door system for maintenance?

There is no specific amount of time (every month) for conducting regular maintenance. Technicians recommend testing your garage door opener remote controls once per month to ensure they are working properly (including the safety-reversal feature). You should also change the remote batteries once a year or anytime you notice decreased range from the remote.

What type of battery do garage door remote controls use?

 Garage door opener remotes typically use either small coin-style (CR2032 or CR2025) or AA/AAA batteries. Consult the information on the remote packaging and/or remote owner's manual for the needed type of battery, and use a new, quality brand battery.

 Is it possible for a remote to wear out?

 Yes. Like all electronic devices, remote controls can eventually go bad. If replacing the batteries and programming the remote do not solve the problem, you will likely need to replace the remote.
