The last thing you want to deal with after a long day at work is a garage door keypad that just won’t work. There you are, sitting in your car in the driveway, wasting gas, while you punch in your PIN over and over, but the garage door remains stubbornly closed.

But this doesn’t have to be an issue. Now you can troubleshoot your faulty garage door keypad and stop wasting time trying to get inside your house. Just follow these steps for how to fix your garage door opener.

Replace the Battery

It’s a simple fix, but it’s one that’s easy to overlook. Before you start fussing around with changing your garage door code or other complicated fixes, try changing the battery in your keypad. Most models will use either a 9-volt or a 12-volt battery.

After you have changed the battery, you might need to reprogram your garage door opener keypad. You might even need to go so far as clearing the memory and resetting the PIN.

Check for Frayed Wiring Inside the Keypad

The most common cause of trouble with garage door keypads is frayed connections inside the remote. If you’re having problems with one or more specific keys, it’s likely that some frayed wiring inside the remote is the culprit. 

Open up your garage door remote and look for frayed wires or loose connections between the wires and the keys. Detach any loose or frayed wires completely and then reattach them to the keys in question. Do this one wire at a time so you don’t get mixed up. Make sure the connections are secure before you put the remote back together.

Give the Keypad a Good Cleaning

If keys are getting stuck on your remote when you press them, chances are you need to give the remote a good cleaning to remove grime, oil and debris that can gum up the works. Wipe off the outside of your garage door remote with some appliance cleaner on a rag. Carefully clean between the keys.

Next, open up your garage door opener remote and clean the inside. Sweep out dust with a soft brush. If possible, remove the keypad from the remote entirely and clean the whole thing. Take care to put the keys back in their proper position when you reassemble the remote. Take some pictures with your phone before you disassemble the remote so you don’t forget what position the keys were in.

Reset Your PIN

If you’re having trouble getting your garage door opener to accept your PIN, don’t just sit there repeatedly punching the digits into the keypad. Doing so could cause the garage door opener to lock up. You’ll want to figure out how to change the garage door PIN code. You’ll also want to change your PIN if you suddenly can’t open the door anymore, but you can close it from the inside using the same PIN — this means that your PIN was temporary and has expired.

For most models, you’ll start by getting out your owner’s manual and looking for the unlocking code, which is usually four digits long. Enter the unlocking code, and when the light on the motor starts blinking, press the release button on the unit and reset your PIN according to the manufacturer’s instructions.

Reboot the Garage Door Opener

As a last resort, if you can’t get your garage door opener keypad to work or you’re having persistent problems with the system, reboot the whole thing. To do this, turn off your garage door opener and unplug it for five minutes. This should erase any data in the memory and allow you to start fresh.

Is It Time for a New Garage Keypad?

If you’re having problems with your garage keypad, it’s worth considering what condition it’s in, especially if you’ve had persistent problems and these troubleshooting tips don’t fix them. If your garage door keypad is damaged, it might be time to replace it. Before you start troubleshooting, inspect the keypad for cracks, damaged or missing keys, or other signs that it’s time for replacement. Many companies make universal remotes and keypads that will work with any garage door opener, so you don’t have to install a new system just because your keypad has worn out.

Whenever a home system or appliance breaks down or starts acting up, trying to troubleshoot yourself is often your first instinct — and for good reason. If you can figure out the fix yourself, you’ll save time and money.
