How to Program a Garage Door Remote, Keypad or Car Button

Programming a remote (LiftMaster and Chamberlain)

1. Replace the remote battery if it's old. A weak battery can keep a remote from programming or reaching the opener.
2. Press and release the learn button on the opener. The LED next to it stays lit for about 30 seconds.
3. Within 30 seconds, press and hold the remote button you want to use.
4. Release when the opener lights flash or you hear two clicks.
5. Test it from inside the garage with the doorway clear.

Chamberlain also describes a method using certain wall controls that have a learn button: press it twice, then press the remote button within 30 seconds. That saves the ladder.

Programming a wireless keypad

For several LiftMaster keypad models, Chamberlain's instructions using a wall control with a learn button are:

1. Clear the doorway.
2. Press the learn button on the wall control twice. The command LED flashes.
3. On the keypad, enter a 4-digit PIN of your choice and press Enter.
4. The opener lights blink to confirm the PIN is set.

To change an existing PIN on those keypads: enter your current PIN, press and hold # until the opener light blinks twice, enter the new 4-digit PIN and press Enter. The lights blink once when it's changed.

Keypad models differ, so check the model number on the back of the keypad against your manual. If the keypad stopped working suddenly, try fresh batteries before reprogramming.

Car buttons: HomeLink, Tesla and built-in openers

Many cars have HomeLink buttons on the visor, mirror or overhead console. Chamberlain's pairing steps, in short:

1. Park outside the garage with the door clear.
2. Hold your working handheld remote 1 to 3 inches from the car's HomeLink button.
3. Press and hold both buttons until the car's indicator light changes from a slow to a rapid flash.
4. For rolling-code openers, you'll then need to press the learn button on the opener and, within 30 seconds, press the HomeLink button in the car to finish (you may need to press it more than once).

Two tips from Chamberlain's support pages:

• On some Audi, Porsche and Tesla models the HomeLink receiver is in the front bumper, so hold the remote near the bumper instead of the visor.
• If your car won't pair with a yellow-button Security+ 2.0 opener, LiftMaster sells a HomeLink compatibility bridge that translates the car's signal.

Some newer cars skip HomeLink and connect through the myQ app instead. Chamberlain's list of official myQ partners includes Tesla, Honda and Acura, Kia, Nissan and INFINITI, Mercedes-Benz, Volkswagen and Mitsubishi, among others. See our smart opener guide for details.

Genie programming differences

Genie uses a program button and colored LEDs instead of a colored learn button. From Genie's instructions for its 3-button remote:

Newer Genie openers

1. Press and hold the program button on the powerhead until the round LED turns blue, then release. The long LED flashes purple.
2. Stand at least 5 feet away and slowly press the remote button you want twice. The opener LEDs flash and go off.
3. Press the button a third time. The door should move.

Older Genie openers (about 1995–2011)

Press and release the learn code button once (a red LED flashes), then press the remote button using the same presses as above.

Genie wireless keypad

1. Set your PIN: press 3-5-7, then program (the keypad LED blinks once per second), enter a 3 to 8-digit PIN, then press program again.
2. Put the opener in program mode as described above.
3. Enter your PIN on the keypad, then press up/down slowly three or four times until the door moves.

Genie remotes use a CR2032 coin battery, and Genie notes that changing the keypad's AAA batteries doesn't erase its programming.

Erasing lost or stolen remotes

If you've moved into a new house, lost a remote, had a car stolen, or had a contractor or former tenant with a remote, erase everything and reprogram only the devices you have. It's one of the simplest security steps you can take.

After erasing, reprogram every remote and keypad you're keeping, and re-pair car buttons. Chamberlain notes that unplugging the opener does not erase remotes, so don't rely on that.

Troubleshooting when programming fails

• Fresh battery in the remote or keypad
• Lock mode off: on LiftMaster and Chamberlain wall controls, a constantly flashing LED means remotes are locked out; hold the lock button about two seconds
• Right technology: the remote matches your learn button color
• Antenna wire hanging straight down from the opener, not tucked up or damaged
• Light bulbs: Chamberlain warns that low-quality LED bulbs in the opener can interfere with remotes; try removing them to test
• Timing: finish within 30 seconds of pressing learn

If the wall button works but no remote will program, the opener's receiver or logic board may be failing. See opener repair, or if your opener is from the green or red-button era, our opener installation cost guide can help you weigh an upgrade. Door doesn't respond at all? Check garage door won't open.
