How to change or program code on your Craftsman Liftmaster keyless keypad made by Chamberlain.

1. Program using the "Learn" Button

2.
Within 30 seconds, enter a four digit personal identification number (PIN) of your choice on the keypad. Then press and hold the ENTER button.

3. Release the button when the motor unit lights blink. It has learned the code. If light bulbs are not installed, two clicks will be heard.



Program using the Multi-Function Door Control

NOTE: This method requires two people if the Keyless Entry is already mounted outside the garage.

  1. Enter a four digit personal identification number (PIN) of your choice on the keypad. Then press and hold ENTER.
  2. While holding the ENTER button, press and hold the LIGHT button on the Multi-Function Door Control. Both of these should now be held down at the same time.
  3. Continue holding the ENTER and LIGHT buttons while you press the push bar on the Multi-Function Door Control (all three buttons are held).
  4. Release buttons when the motor unit lights blink. It has learned the code. If light bulbs are not installed, two clicks will be heard.


Change an Existing, Known PIN



If the existing PIN is known, it may be changed by one person without using a ladder.

  1. Press the four buttons for the present PIN, then press and hold the # button. The opener light will blink twice. Release the # button.
  2. Press the new 4-digit PIN you have chosen, then press ENTER.

The motor unit lights will blink once when the PIN has been learned.

Test by pressing the new PIN, then press ENTER. The door should move.




Your new Keyless Entry must be programmed to operate your garage door opener

Try this first before calling a repair company. When the door is finished moving and it is open release the handle that disengages the door from the actuator and then close the door by hand. then re engage the handle and operate the door. If everything works fine after that, there is no need to call for a repair.

Fool with the down and up force adjustments on the back of the opener.
