A keypad that went dark or won't take your code. A remote you have to wave at the door from ten feet away. These are some of the easiest garage door problems to fix, once you know which part is at fault.
Quick answer: Most keypad and remote trouble comes down to a dead battery, lost pairing, or a remote that doesn't match the opener. Those are fast fixes. A keypad with a cracked cover or water inside usually needs to be replaced. If the opener is very old, it may not work with any remote sold today.
Most LiftMaster and Chamberlain openers have a Learn button on the motor unit, under the light cover or on the side. For a remote, you press Learn, then press the remote button within about 30 seconds. The opener light blinks or you hear a click when it takes. For a keypad, you press Learn, then enter your code and press Enter. The steps are close to the same on most brands. Our guide to reprogramming a garage door remote covers it step by step.
On LiftMaster and Chamberlain openers, the color of the Learn button tells you what kind of signal your opener uses. A new remote or keypad has to match it. If you buy one at the store, check the package against that color before you open it.
Remote signals have changed over the years. An opener from the early 1990s may not work with any remote you can buy now. Openers that old are also often missing the safety eyes that are now required. If that is your setup, a new opener is the better fix. See how the main brands compare in LiftMaster vs Chamberlain vs Genie.
The buttons built into your car's mirror or visor are their own case. Some cars need an adapter to work with newer LiftMaster openers. If you want to open the door from your phone instead, read our smart opener and Wi-Fi guide first.
We test the batteries and the signal, check the antenna and the opener light bulbs, and pair every remote and keypad you have. If a remote was lost, we erase the opener's memory first so the lost one stops working. If the keypad is worn out, we mount a new one at least 5 feet off the floor, out of small kids' reach. If the problem turns out to be the opener itself, our opener troubleshooting guide shows what we look for next.
Take a photo of the label on the motor unit and the Learn button. That tells us the brand, the model, and the signal type, so we can bring the right keypad or remote. No charge to look at it. If a new battery was all it needed, we will tell you that on the phone.
Start with the battery. If the keypad lights up but the door does nothing, the keypad has most likely lost its pairing with the opener. That happens after the opener’s memory is cleared or the opener is replaced. Pairing it again takes a few minutes.
On most LiftMaster and Chamberlain openers, you hold the Learn button on the motor unit until its small light goes out. That erases every remote and keypad paired to it. Then you pair the ones you still have. If you are not sure you got them all, we can do it with you.
Many will, if the package lists your opener’s brand and the type of signal it uses. Very old openers and some newer ones are the exceptions. Tell us the brand and model on the motor unit and we can tell you what will work.
A weak battery is the most common reason. After that, check the antenna wire hanging from the motor unit, which should hang straight down and not be tucked up. Some LED bulbs in the opener light also interfere with the remote signal. Taking the bulb out for a test will tell you.
At least 5 feet off the floor, out of small kids’ reach, which is what the opener instructions call for. It should also be out of the path of the door and easy to see from the driveway.
