The definitive guide to troubleshooting your garage door keypad

Automatic garage door openers have come a long way from the single, wall-mounted push buttons of yesteryear. Today’s openers are frequently equipped with advanced safety features, including the ability to transmit notifications to your smartphone whenever someone enters or exits your garage. The most common safety feature available on modern garage door opener control panels, however, is a keypad on which you enter a secret four-digit code in order to gain access to the garage. It’s simple, convenient, and secure—which are important criteria when it comes to any garage door accessory.

At NationServe, we carry, install, and service a wide selection of Genie garage door openers for homeowners in Cincinnati to Tucson and beyond. We know each brand’s owner manuals by heart, so when one of our clients comes to us with a question, you can bet that we have an answer. Here are some of the most common questions we get on the topic of troubleshooting garage door opener keypads.



Why isn’t my garage door keypad working?

Because it’s fixed to the wall, it’s easy to forget that your garage door opener keypad is indeed battery operated. Dead batteries are by far the most common culprit in malfunctioning keypads, so be sure to check that first. If your keypad still isn’t working with fresh batteries, you may be dealing with faulty internal wiring, which is best left to the experts.

Can I change the code for my garage door opener?

Absolutely. There are many situations in which you might need to change the four-digit access code for your garage door opener (it isn’t always for security reasons, either—if you plain old forgot yours, you’re not alone. It happens.). Furthermore, it doesn’t matter if you’re in Cincinnati or  Colorado Springs; changing your garage door keypad’s entry code every once in a while is simply a smart thing to do to ensure the safety of your home and family. The good news: whether your garage door opener is a Genie, a LiftMaster or any other brand, resetting the entry code follows roughly the same straightforward process. Here’s the step-by-step.

You’ll need:

  • A ladder
  • Your garage door opener remote
  • If possible, someone to lend a hand

Steps to reset your garage door opener code

  1. Position your ladder so that you can reach the garage door opener motor, and safely climb on up.
  2. Locate the “Learn” button on the side of the motor. Press and hold the button until the adjacent light turns off, signaling that that the old code was erased from memory.
  3. Press the “Learn” button again. You should see the light come back on.
  4. Ask your helper to enter the new code on the wall-mounted garage door opener keypad. Once this is done, you should see the light on the motor blink to indicate that the new code has successfully been recorded.
  5. Press the “Learn” button once more, and then press any button on your garage door opener remote control. Once you see the light on the motor blink, you’re all set. Remember to do this with each of your remotes so you don’t leave any of your loved ones stranded out in the cold.

How do you reset a garage door opener after using it manually?

Our clients who request garage door service in storm-prone areas such as Houston often wonder how to re-enable their automatic opener after using it in manual mode during a power outage. Our answer: it’s easy as pie! Just follow these steps:

  1. Make sure the door is open. Garage doors are deceptively heavy, so if you’re having a hard time lifting it all the way up on your own by pulling the red cord, ask someone for help. Safety first! If you’re unable to easily open the garage door with the red cord, you may request one of our experts to service your garage door.
  2. Once the door is completely open, pull on the red cord at an angle until you hear a clicking sound. This signals that the door is secure.
  3. Next, push the open/close button on your garage door opener. This should cause the trolley to automatically move back into place and connect to the door. That’s really all there is to it! If this doesn’t work, give your nearest NationServe location a call. Our team will be more than happy to assist.

If your garage door won’t close, it could be a different problem all together. We have more information to help you troubleshoot this problem here.
