Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+

Changing PIN on Key Pad

I do not have the manual for the opener. I went by the instructions on the lid of the outside Key Pad to change the PIN from the old one to a new one. The problem is, it did not cancel out the old one, now both numbers work to open and close the door...
How do I get rid of the old number?

Thank you,

OCBurruz

You need to reprogram the system please follow the instruction:

To re-set your code, please follow the steps outlined below:
1) Unplug your garage door opener from the electrical outlet.
2) Open the cover on your inside wall console. You should see a 9 Volt battery and an adjacent PROGRAM/OPERATEswitch. Slide the switch to PROGRAM.
3) Enter your new 4-digit code into the keypad outside.
4) Slide the switch back to OPERATE and replace the console cover.
5) Plug the garage door opener back in to the electrical outlet.
6) Test the new 4-digit code. (If the keypad does not illuminate, replace the 9 Volt battery)

    How do i change the numerical code?


    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

    THE KEYPAD NO LONGER ACCEPTS MY 4-DIGIT CODE. MUST HAVE HIT THE STAR KEY OR SOMETHING & ERASED IT. HOW CAN I RESET IT? THE INSTRUCTION ON THE PAD LET YOU CHANGE IT, BUT SAYS NOTHING ABOUT RESETTING...


    If your battery is good and you have followed the instructions for changing it then your keypad is bad. The instructions for changing the code is the same as resetting it.
