How to Set or Change Your Garage Door Keypad Code
To set or change your garage door keypad code, press the "Learn" button on the motor unit (or open the cover and use the keypad's program sequence), enter your new 4-digit PIN, and press Enter to lock it in. The whole thing takes about two minutes and you don't need any tools. The exact button presses vary a little by brand, but every keypad follows the same basic idea: put the opener (or keypad) into learn mode, type your code, then confirm it.
Step by step
-
1
Find your opener's Learn button and the keypad model
Most modern keypads sync to the opener through a Learn button on the back or side of the motor unit (you'll usually need a step stool). It's a small colored button — often purple, yellow, orange, red, or green — frequently next to a matching LED light. The color matters because it tells you the brand's protocol: LiftMaster and Chamberlain use a colored Learn button, while Genie uses a 'Program Set' or 'Learn Code' button. Note the keypad brand too (it's printed on the front), since the keypad's own keystroke sequence depends on the maker, not just the opener.

Put the keypad into programming mode
On most LiftMaster/Chamberlain keypads, flip up the cover, enter your existing PIN (or the factory default printed in the manual), then press and hold the * and # keys together until the keypad light flashes or stays lit. On Genie Intellicode keypads, press the PROG button. This tells the keypad you're about to enter a brand-new code. If you've never set a code, the keypad ships with a temporary default — check the sticker inside the cover or the manual.

3
Enter your new 4-digit PIN
Type a new 4-digit code that's easy for your family to remember but not obvious to a stranger. Skip birthdays, your street address numbers, or 1-2-3-4 — those are the first things someone would try. Press Enter (or # on some models) after typing it. Avoid sequential or repeated digits, and don't reuse the code from your old house.

4
Sync the keypad to the opener using the Learn button
Within about 30 seconds of entering your new PIN, climb up and press the Learn button on the motor unit once. The opener's light will blink or you'll hear a click — that's it accepting the keypad. Come back down and type your new code, then Enter. The door should open. If it does, the keypad and opener are now talking to each other.
-
5
Test the new code twice, then close the cover
Run the full sequence two or three times from a fully closed door: enter the PIN, watch it open, close it, repeat. Testing twice confirms the code actually saved and wasn't a fluke. Snap the keypad cover shut so weather and curious fingers stay out, and make sure the keypad housing is sealed if it's exposed to rain or direct sun.

Wipe out any old or forgotten codes
If you bought the home, inherited the keypad, or just want a clean slate, clear all existing remotes and codes by pressing and holding the Learn button until the LED goes out (about 6–10 seconds). Heads up: this erases every paired remote and car button too, so you'll need to re-pair those afterward. This is the single most important step after moving into a new house — you have no idea who the previous owner shared the code with.
When to call a pro
Call a pro if the Learn button does nothing, the keypad won't light up even with fresh batteries, the code won't save after several tries, or your opener is so old it has DIP switches instead of a Learn button — these point to a dead keypad, a failing logic board, or an incompatible accessory that's worth a technician's eye.

What's the default code on a garage door keypad?
There usually isn't a universal factory PIN you type in — most keypads make you create your own code the first time, then sync it to the opener with the Learn button. A few brands ship with a temporary code printed on a sticker inside the keypad cover or in the manual. If you can't find one, just run the full programming sequence and set a fresh code; that overrides anything from the factory.
How do I change the code without the old PIN?
You don't need the old PIN if you use the opener's Learn button. Press and hold Learn on the motor unit until the LED turns off to wipe the keypad's memory, then re-program a brand-new code from scratch. The catch: holding Learn that long also erases your remotes and any in-car buttons, so re-pair those right after. This is the go-to method when you've forgotten the code or moved into a new home.
How many digits can a garage keypad code be?
Most residential keypads use a 4-digit PIN, though some LiftMaster and Genie models accept anywhere from 4 to 6 digits. Longer is a little more secure, but the bigger security win is avoiding obvious numbers like 0000, 1234, or your house number. Pick something your family will remember without writing it on the keypad.
Why does my keypad work intermittently or stop working in cold weather?
Nine times out of ten it's a weak battery — keypads run on a 9-volt or coin-cell battery that drains faster in cold temps, causing flaky presses and short range. Swap the battery first. If it's still spotty, check that the keypad isn't mounted too far from the opener or blocked by metal, and look for moisture inside the housing. If a fresh battery and a re-program don't fix it, the keypad itself may be failing and worth replacing.
