If the keypad is hardwired, do this:

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.

Craftman belt 1/2 hp garage opener with security sensor plus system. All remotes and homelink programed. Unable to get keypad to work. Enter code with light switch pressed then top bar pressed and nothing,...


The simplest way to program the keypad is to press and immediately release the smart/learn button and then walk over to the keypad and key in your 4 digit code and press enter. If this doesn't work the keypad is bad or you have the wrong keypad. You don't say why you are programming everything so I am guessing about the wrong keypad part.

My Craftman Garage Door Opener is approx. 7 yrs old. Remotes work fine. Keypad acknowledges receiving code, but then will not open door. Installed new bsttery.


If your keypad is the same age as your door and worked before it has probably just quit. If it is new and you have programmed it and it still doesn't work it may be the wrong one for your model opener.

Can not program both keypad & remote to operate at the same time


One of your units has reverted from "rolling code" to "billion code" and as you have found they will each work but will not work with each other. The problem is finding out which unit reverted. The most common one is the hand remote but that could be wrong.
