I need to change the key pad to my chamberlain whisper drive garage door opener. Recently got divorced and ex has the origional key pad entry number. I can not find anywhere that knows how to change it. HELP!

Locate the smart/learn button on the rear of the motor unit near where all those white wires go. Press and immediately release this and then walk over to the keypad and key in any 4 digit code you like and press enter.

You just have to reset everything on the opener itself. Re-program all you hand held remotes as well as create a new pin for your keypad. This should take of it.

If the wall button will operate the door up but none of the devices do then look at the wall button. Find the lock button and push it for 2 seconds and then try the remotes again. This is your vacation lock. You can get a manual at chamberlain.com. Now if the door does not open or close with the remotes you can reprogram them. Press the colored learn button on the motor head and then press the button on the remote. Repeat for each remote. If they fail to program you will need a new logic board. Thanks BB

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.

Make sure you didn't accidently knock a wire off the rear of the motor unit. The wires connect to terminals 1 and 2 for the wall control.

There isn't a trick but you must make sure you got the right remotes for your opener. The receiver which is part of the logic board can quit working and it sounds like this may be the case in your situation.

Does it work from wall button? Hit learn button for 10 seconds. Hit again for 1 second and code keypad.Opener lights should blink 2x. Hit learn again for a second and hit button on a remote (Any button you chose). Again, lights should blink. Now should work. Repeat for any other remotes.

Follow this link for the manual and look on page for programming.

How do you change the code?

THE FREQUENCY OF THE UNITS ARE PROBABLY NOT COMPATABLE THEY CHANGED ABOUT 2 YEARS AGO.

SORRY - I THINK YOU NEED A NEW KEYPAD TO GO WITH THE NEW OPENER.
