How to Reset Your Garage Door Opener (Step-by-Step)
To reset most garage door openers, unplug the unit (or flip its breaker) for about 30 seconds, plug it back in, then re-pair your remotes and keypad by holding the "Learn" button on the motor head and pressing your remote button until the opener light blinks. This power-cycle clears the unit's memory and fixes most glitchy or unresponsive openers. If you're trying to reset because remotes were stolen or you bought the house from someone else, you'll want to fully erase all saved codes first, then re-program only your own devices.
Step by step
-
1
Power-cycle the opener (the quick fix)
Unplug the opener motor unit from the ceiling outlet, or flip its breaker off, and wait a full 30 seconds. This drains residual power and forces the logic board to restart. Plug it back in. Roughly 7 out of 10 times, a frozen or randomly-acting opener wakes up working again, and you can stop right here. If the door still won't respond, keep going.

2
Find the 'Learn' button on the motor head
Pull the dangling red rope to disconnect only if you need to move the door by hand; otherwise leave it engaged. Set up a step ladder and look on the back or side of the motor unit (the box bolted to the ceiling) for a small square 'Learn' or 'Smart' button, usually colored purple, yellow, orange, green, or red. The button color tells you the security format, so note it. There's often an LED right next to it.

3
Erase all old codes (do this if remotes were lost, stolen, or you're a new homeowner)
Press and HOLD the Learn button until the LED next to it goes out, which takes about 6 to 10 seconds, then release. This wipes every remote, keypad, and in-car HomeLink code the opener has ever stored. Skip this step if you're only adding a device or fixing a glitch, because it forces you to re-pair everything.

Re-pair each remote control
Press and release the Learn button once (the LED turns on solid for about 30 seconds). Within that window, press the button on your remote firmly once or twice. When the opener light blinks or you hear a click, the remote is paired. Repeat for every remote. Test each one from inside the garage before climbing down.

5
Re-program the wireless keypad
Enter your desired 4-digit PIN on the keypad and press Enter (some models have you hold Enter, or press a brand button like 'Send'). Then press the Learn button on the motor and, within 30 seconds, press Enter on the keypad again. The light blinks to confirm. Now test the keypad and reset the PIN to something only you know.

6
Re-sync your car's HomeLink or Car2U buttons
Hold the chosen in-car button until its indicator flashes rapidly, hold your working hand remote next to it until the car light flashes fast too, then go press the Learn button on the opener once and tap the in-car button two or three times. On some newer rolling-code openers this last step at the motor is required, so don't skip the ladder trip.
When to call a pro
Call a pro if the opener has no power after you've checked the outlet and breaker, if the Learn button or logic board appears burned, dead, or unresponsive after a reset, or if the door reverses, won't close, or moves unevenly, since those point to safety-sensor or spring problems rather than a programming issue.

Will resetting my garage door opener erase my remotes and keypad?
A simple power-cycle (unplugging for 30 seconds) does NOT erase your saved remotes; it just restarts the unit. But holding the Learn button until the LED goes dark performs a full memory wipe, which does delete every remote, keypad, and HomeLink code. After a full wipe you'll need to re-pair each device, so only do that when you specifically want a clean slate, such as after losing a remote or buying the home.
Where is the Learn button on my garage door opener?
It's on the back or side of the motor unit mounted to your garage ceiling, near where the antenna wire hangs down. It's a small square button, often purple, yellow, orange, red, or green depending on the brand and year (Chamberlain, LiftMaster, Genie, and Craftsman all use this layout). You may need to remove a light-bulb cover or a small panel to see it. Its color also tells a technician which security code format your opener uses.
I just moved into a new house. How do I reset the opener so the old owner's remotes don't work?
Climb up to the motor unit, press and hold the Learn button until the LED light goes out (about 6 to 10 seconds), and release. This erases every code the previous owner ever programmed, including their car's HomeLink and any keypad PIN. Then re-pair only your own remotes and set a brand-new keypad PIN. This is the single most important security step when moving into a home with an existing opener.
My garage door opener still won't work after a reset. What's wrong?
Check the basics first: is the wall-control button working (which rules out the opener itself), and are the two safety sensors near the floor lit solid and aligned? Misaligned or dirty sensors are the number-one reason a door won't close even when the opener has power. If the wall button is dead and the unit got no power back after the breaker reset, or you smell anything burnt, the logic board or capacitor may have failed and it's time to call a technician.
