Chamberlin Liftmaster keypad entry does not worek


It will only take a 4 digit program code. After you program the code, and then enter that code to open the door, hit an additional number on the keypad. Some need the additional digit to act like an 'enter' key.

I have a craftsman 3/4HP opener, it will only let me program ONE remote or keypad at a time. what do I need to do??? Mod # 139.53924


Either you have a bad remote/keypad or you are trying to program older units with a newer opener. Find the unit that doesn't work with the rest and replace it.

Post the model number of the opener and the model numbers of the remotes. The opener model number is found on the end closest to the door and starts with 139.

Try programming the keypad like this:

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.

After programming the keypad see if either remote will work with it. Post this information also.

I have LiftMaster garage door model 41A3039 and Chamberlain wired keypad--how do I change the keypad code to open the garage door


To program the keypad, first unplug the garage door opener from the electrical outlet. Next remove the nameplate from the console that the keypad plugs into and locate the program/operate switch. Flip the switch to program. Next enter your desired four-digit PIN number into the keypad. Slide the switch back to operate and plug the garage door opener back in. The keypad should be programmed.

Keypad won't work anymore


Lets make sure you are programming it correctly, make sure the battery is new. Press and release the learn button on the motor. Within 30 seconds enter in the 4 digit code followed by the up/down button. The light bulb should flash once. If you can't get it to code in this way you will need to replace the keypad. Thanks BB

Help w/ programing keypaqd along w/remotes


I press the learn button on the door motor. I wait a few seconds and press a new 4 digit code into the keypad, hold down on the "enter" button for several seconds so it learns the code. Now the remote will not work. Press the learn button again, press the button on the car remote until the light on the motor blinks. Both should work after that.
I have Sears LiftMaster products. Hope that helps.
