Hello there,
It actually depends on what you are trying to program. And these instructions apply only to openers that do not have dip switches on them.
Remotes: push don't hold the colored learn code button all models have different colors. After pushing the button hold the remote behind your back and push it three times. On the third time the door should run.
Keyless Entry: Program the code you want into the keyless. Push the colored learn code button and then enter the code and push enter three times slowly. on the third time the door should run.
Home-Link. Hold the two outer buttons until the blinking pattern changes. Then hold the button you wish to program and point and click your remote at it. Push the colored learn code button and push the homelink button three times.
There are two models of the Wireless Keyless Entry System, the 740CB and the 940CB. The 940CB is for use only with Security+® garage door openers having an orange/red smart/learn button. The 740CB will work with all openers manufactured since 1990 that have a yellow, white, gray, or green smart/learn button. It will not work with Security+® openers.
To program the keyless entry, first locate the smart/learn button. On our chain drive models, this button is on the end farthest from the door. On our belt and screw drive models, it is on the right side as you face the door from the opener. You simply press and release the smart/learn button. You now have 30 seconds to enter your four digit PIN number into the keypad and hold the enter button for five seconds. Wait one minute and test the keyless entry by entering your four-digit PIN number and pressing enter.
With some Security+® models, you can also program your Model 940CB Wireless Keyless Entry without climbing a ladder, right from your Multi-Function Control Panel. Simply enter your pre-selected code and press and hold the enter button on your Keyless Entry. Then press and hold the light button and the pushbutton on your Multi-Function Control Panel. The garage door opener lights will flash to confirm that the Keyless Entry has been successfully programmed.
Hope this helped you solve the problem. All the best my dear friend. Elect_Comp

How do I change the keyless entry code to another number


How to change the code on a Chamberlain Keyless Entry Garage Door opener

How do I add, program or change a Keyless Entry PIN?

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

Program using the "Learn" Button

  1. Press and release the "learn" button on the motor unit. The learn indicator light will glow steadily for 30 seconds.
  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.
  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 a Known, or Existing Pin/Code

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 light on the motor will blink once when the PIN has been learned.

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


I hope you find this helpful. If you need further assistance please let me know!

Have a great day! :)

If that keypad quit after working since 1997 and a new battery didn't get it going it has just gone bad. The model number listed for your opener is now 53876.

We have a Chamberlain Whisper Drive Plus. The keyless entry stopped working, suddenly. I have changed the battery, not the problem. I cannot get it to work, and cannot get it to reprogram. The keypad lights up when buttons are pressed, but when I press "Enter" the whole keypad flashes for about 30 seconds and then just goes dark.

You have to press a Yellow/Purple button on the back of the garage door opener unit.
It is the LEARN button. Then enter a new four digit code into the keypad and press the enter button.
The unit should click and the lights should flash. This acknowledges it has learned the new code.
