Trouble changing passwordon model 940CB wireless keyless entry

When attempting to change the password, instructions tell me to enter current password and press and hold # key. Opener light should blink 4 times. Light doesn't blink, but door opens. If I let door close completely, I am unable to open the door using the keyless pad. I am unable to change the password. Can you help?

    Mine is model 940CB. I already have the instructions--they simply don't work.

  • Syls May 20, 2008

    I have the printed instructions. They simply don't work. Yes, I did try setting up a temporary pin first and that too doesn't work.

I took a ladder went up and pushed the learn button once. The light comes on steady, then go to the remote and put in the 4 digit code you want and press enter. That's it, it worked.

In Canada Chaimberlain has a really helpful telephone line with an IVR that does get you to the fix quickly. And it did solve my issue with the remote. My problem was the previous owner of the house did not leave the code. The basic steps were.
1. Make sure the battery is good.
2. On the motor unit of the actual garage door opener press the learn button, mine was under a white plastic bulb cover that I had to remove.
3.While the learn button LED remains on for 30 seconds, on your keyless remote type in your four didget code that you want and then hold down the enter button for 5 seconds.
4. The light on the motor unit then started to flash confirming it had learned the code from the keyless remote.
5. Try the keyless remote by pressing your four didget code, then pressing enter. Your door should work.

To the guest's question. normally on liftmaster products you need to hold the 'learn' button on the back of the operator for 8-10 secs (till the led goes out). Then have all your remotes and keypad handy and reprogram them all. Push the button on the back of the unit then one of the remotes (1-2 sec) light will flash. Then repeat for the keypad press button and go enter your 4 digit code and hold enter 1-2 sec.

Hi Syls

Click HERE to view the online manual.

Is the buttons flashing the required two times once you've held in the # key ?

Try setting up a temporary pin first and then changing it back to a normal one again.

Let me know once you've tried it please.

    Hi Syls



    I think that the keypad is faulty and will most probably need replacement because it is not even flashing the same number of times when you enter the new pin either standard or temp. mode.



  • Marnus Jacobs
    Marnus Jacobs May 20, 2008

    Hi Syls



    Have you tried switching off the power for 12 hours and then retrying the procedures yet ? This should do a hard reset wich might just do the trick.



    The power should in other words be shut off completely.

Chamberlain Garage Door opener model 3850. Sometimes the keypad will not open door. Instead the lights behind all the numbers blink in unison. What is it trying to tell me? Thanks Jim


The blinking lights are normal when you enter a code and press enter. I would try programming it and if that doesn't work replacing it. To program it you press and immediately release the smart/learn button on the rear of the motor unit and then key in your 4 digit code and press enter.
