It sounds like the keypad has lost signal strength. Make sure the battery is good. If it acts the same way with a good battery you will have to replace the keypad.

Hello there,
It actually depends on what you are trying to program. And these instructions apply only to openers that do not have dip switches on them.
Remotes: push don't hold the colored learn code button all models have different colors. After pushing the button hold the remote behind your back and push it three times. On the third time the door should run.
Keyless Entry: Program the code you want into the keyless. Push the colored learn code button and then enter the code and push enter three times slowly. on the third time the door should run.
Home-Link. Hold the two outer buttons until the blinking pattern changes. Then hold the button you wish to program and point and click your remote at it. Push the colored learn code button and push the homelink button three times.
There are two models of the Wireless Keyless Entry System, the 740CB and the 940CB. The 940CB is for use only with Security+® garage door openers having an orange/red smart/learn button. The 740CB will work with all openers manufactured since 1990 that have a yellow, white, gray, or green smart/learn button. It will not work with Security+® openers.
To program the keyless entry, first locate the smart/learn button. On our chain drive models, this button is on the end farthest from the door. On our belt and screw drive models, it is on the right side as you face the door from the opener. You simply press and release the smart/learn button. You now have 30 seconds to enter your four digit PIN number into the keypad and hold the enter button for five seconds. Wait one minute and test the keyless entry by entering your four-digit PIN number and pressing enter.
With some Security+® models, you can also program your Model 940CB Wireless Keyless Entry without climbing a ladder, right from your Multi-Function Control Panel. Simply enter your pre-selected code and press and hold the enter button on your Keyless Entry. Then press and hold the light button and the pushbutton on your Multi-Function Control Panel. The garage door opener lights will flash to confirm that the Keyless Entry has been successfully programmed.
Hope this helped you solve the problem. All the best my dear friend. Elect_Comp

Seems you've done everything right. Press and immediately release the smart/learn button and then walk over and key in a 4 digit code and press enter. If you are sure the battery in the keypad is good then I think your keypad is on the fritz or the wrong one for that opener.

You can try programming it but I have a feeling it is bad.

Locate the smart/learn button on the rear of the motor unit. Press and immediately release this and then walk over to your keypad and key in your 4 digit code and press enter.

If this doesn't work you will need a new keypad.

Craftsman Model 139.53684 Keyless entry doesn't work


The remotes and keypad use the receiver which is part of the logic board.'t The button on the wall is hardwired and doesn't use the receiver. You might pull the logic board and check for bad connections on the printed circuit.

    I have a craftsman garage opener and my lock won't work


    The wireless keypad should work but the remotes should not. I suspect a bad wall control but there is a possibility of a bad logic board. If you have a neighbor with a 3 button wall control see if they will let you borrow it to eliminate that problem. Just make sure you note which wire goes where on the back of the control. They are color coded.
