How To Erase All Codes on LiftMaster Garage Door Opener
This is the most common method and works on almost all LiftMaster openers manufactured from the 1990s to today.
H2: How To Erase Codes On LiftMaster Garage Door Opener Using the Learn Button
LiftMaster openers use a Learn Button system, typically located on the motor unit. Using it, you can wipe all saved remotes and keypad codes in seconds.
Step 1: Locate the Learn Button
The Learn Button is usually found:
- On the back panel of the motor
- Within the light cover (older units)
- On the right-side panel (newer Security+ 2.0 models)
Learn Button colors and meanings:
| Learn Button Color | Technology | Approx. Year |
|---|---|---|
| Yellow | Security+ 2.0 | 2011–present |
| Purple | Security+ | 2006–2011 |
| Red/Orange | Security+ | 1997–2005 |
| Green | Billion Code | 1993–1997 |
The erase process is the same regardless of color.
Step 2: Press and Hold the Learn Button for 6 Seconds
Press and hold the button until the LED light beside it turns off (or blinks once on older models).
This action erases:
- All remote controls
- All wireless keypads
- Vehicle HomeLink connections
- Any additional LiftMaster-compatible wireless accessories
→ In other words, your opener’s memory is wiped clean.
Step 3: Reprogram Only the Devices You Want to Keep
After erasing, every device must be re-added manually.
To reprogram a remote:
- Press Learn Button once.
- LED lights up → learning mode.
- Press the button on your remote.
- Opener light blinks → success.
To reprogram a keypad:
- Press Learn Button.
- Enter a new 4-digit PIN on keypad.
- Press Enter.
- Opener light blinks.
Important:
If you skip reprogramming, your garage will not open with any old device.
How To Erase Keypad Codes Only (Without Erasing Remotes)
If your keypad PIN is compromised but you don’t want to erase remotes, use this method:
- Hold down *** and #** on the keypad until the lights stop flashing.
- Enter your existing PIN.
- Press and hold 0 until opener light blinks.
This erases only the keypad, keeping your remotes and vehicle HomeLink intact.
How To Know If Your Codes Were Successfully Erased
You can test the success in seconds:
- Press an old remote
- Try entering the old keypad PIN
If nothing opens the garage, the erase was successful.
If a remote still works, repeat the Learn Button hold for at least 10 seconds.
