How To Change The Code On Liftmaster Garage Door Opener

There are two main ways to change your code:

Let’s go step-by-step.

Step-by-Step Instructions:

1. Locate the Learn button
   • Found on the motor unit (ceiling-mounted)
   • Usually near the antenna wire
2. Press and release the Learn button
   • LED light turns on
   • You have 30 seconds
3. Press the remote button
   • Hold for 3–5 seconds
   • Release when the light blinks
4. Test the new code
   • Press remote again to confirm

👉 This method reprograms remotes with a new secure code.

Step-by-Step Instructions:

1. Press the Learn button
2. Enter a new 4-digit PIN on the keypad
3. Press and hold the Enter button

Steps:
