How to Reset Garage Door Codes in a New Home
Your garage door is often the largest and least-secure entry into your home. Previous owners may have programmed five or more remotes over the years, handed out keypad PINs to neighbors and relatives, and linked their cars' HomeLink systems. A single 10-second button press erases every one of those access points and resets you to a clean slate.

Locating the Learn Button on Your Opener
Every modern garage door opener has a Learn button (sometimes called Smart or Program). It is the master switch for pairing and clearing remotes, and it is almost always on top of or behind the motor unit.
Identify your opener brand
LiftMaster, Chamberlain, and Craftsman are the same platform and use purple, red, orange, yellow, or green Learn buttons depending on year. Genie uses green or red. Linear uses blue. The color indicates the radio frequency and determines which reset sequence to follow.
Find the button physically
Position a stepladder under the motor unit. On most openers the Learn button sits near the antenna wire on the back or side of the unit. Some newer models hide it behind a small plastic cover labeled "Program" that pops off with a fingernail.
Clearing Memory and Reprogramming
The erase-then-add sequence takes less than five minutes once you are on the ladder.
- Clear everything: Press and hold the Learn button for 6–10 seconds until the indicator LED turns off. This single action unpairs every remote, keypad, HomeLink connection, and wireless accessory previously linked to the opener.
- Add your remote: Press and release the Learn button once. Within 30 seconds, press the button on your remote. The opener light flashes or clicks to confirm the pairing.
- Add additional remotes or keypads: Repeat the Learn-then-press sequence for each additional device. Most openers support 5–20 paired remotes.
- Set the keypad PIN: On the exterior wireless keypad, enter your chosen PIN, press enter, then follow the Learn sequence to pair it. Choose a PIN that is not your birthday, address, or common pattern like 1234.
Smart Garage Controllers and App Access
Smart garage hubs like myQ, Tailwind, and Meross sit on top of the opener and let you control the door from an app. They are a separate authentication layer and must be reset independently.
Check if one is installed
Look at the motor unit and the wall-button area for any device with a separate Wi-Fi antenna or status LED. If you see a small box near the opener with a network light, a smart controller is installed.
Factory reset the controller
Hold the reset button on the smart controller for 20–30 seconds until the LED flashes rapidly. This disconnects it from the previous owner's account. Then download the app, create your own account, and pair the device.
Revoke shared access
Once linked to your account, check the app's sharing or guest access section and delete any guest users the previous owner may have added. Smart controllers often retain phantom guest accounts even after a new owner takes over.
HomeLink in Your Vehicles
HomeLink is the built-in rolling-code transmitter in most cars. If the previous owner programmed their vehicles to this garage, the signal still exists until you clear it from the car.
- Clear the car's HomeLink memory: Press and hold the two outer HomeLink buttons on your car's visor or console for 20 seconds until the indicator LED flashes rapidly. This erases all three buttons.
- Program to the new opener: Hold a working remote 1–3 inches from the HomeLink button and press both simultaneously until the LED goes from slow-flashing to solid or rapid-flashing.
- Complete rolling-code sync: Newer openers require you to also press the Learn button on the motor unit within 30 seconds, then press the HomeLink button three times in the car to finalize the rolling-code handshake.
Pro Tips
- •Do it the day you get the keys: A cleared opener takes 30 seconds. Until you clear it, anyone with an old remote can open your garage from across the street.
- •Unplug the opener when on vacation: For extended absences, unplug the opener unit and manually lock the door. No signal can override a physically disconnected system.
- •Keep a manual release tag visible: The red emergency release cord hanging from the trolley lets you disengage the door from the opener during a power outage. Make sure it is intact and accessible.
- •Test safety reversal after reset: Place a 2x4 board flat on the ground in the door's path and trigger the opener. The door must reverse on contact. If it does not, the safety sensors need adjustment before the opener is safe to use.
Frequently Asked Questions
How do I find the Learn button on my garage door opener?
The Learn button is on the motor unit mounted to the ceiling, typically near the antenna wire or under a removable cover. It is usually a raised colored button: purple or red on LiftMaster and Chamberlain, orange on older models, and green or yellow on Genie. You will need a ladder to reach it.
Will clearing the memory affect my smart garage controller?
Smart controllers like myQ or Tailwind connect through the opener's wall-button terminals, not the radio receiver, so clearing the Learn button memory does not disconnect them. You still need to reset the smart controller app separately if the previous owner had it linked to their account.
Do I need to change anything besides the remote codes?
Yes. Change the keypad PIN on any exterior wireless keypad, reset any smart garage controller to factory defaults and link it to your own account, and reprogram the HomeLink buttons in every vehicle that previously opened this garage. A complete reset covers all five access methods: remotes, keypads, HomeLink, smart apps, and manual wall buttons.
