Press and immediately release the learn button and then walk over and key in your 4 digit PIN and press enter. If your opener is older and the keypad is the new generation it may not be compatible with your opener. You need to make sure you take the model number off the motor unit when you order new parts or accessories. The model number starts with 139.

How do I change the code on garage door opener craftsman 139-53975srt1


If this is for the wireless remote control, press the learn button on the opener and then hold the button on the remote.

If you would like to chance the code on a wireless keypad, press the learn button on the opener, type the new 4 digit code on the keypad, and hold the "enter" button on the keypad until the lights flash.

I have a craftsman garage door opener, of which I tried to program a new remote. but it did not program. in the event I accidently errased my keypad password. How can I reprogram the keypad, i cannot...


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

Your keypad may be bad. If you press and immediately release the smart/learn button and then key in your 4 digit code and press enter the keypad should be working. Be sure you have a good battery. Actually the flashing of the keypad is indicating that it is sending the signal to the receiver. Holding the enter button in doesn't do anything extra.

Please describe how tu programing my keyPad for my craftsman 1/2 hp gararage opener.


I am assuming that you want to know how to program your garage opener with a remote control? In that case, open up the garage opener box (its mounted on the roof). You will see a colored button in there somewhere and above it is a small light. That button is called a "learn button." Push the button and hold a button on your remote that you want to program it with and the "learn" button should flash a few times. After it starts to flash, you can release the remote and it should be programed.

My Craftsman 53684 keyless won't work with my Craftsman 53930DM.


I've never seen the first set of steps you mention. You always need to press the "learn" button first so the opener will be in the mode to capture the new code. As far as I know it is not necessary to hold the Enter button on the keypad (at least I never have). While the "learn" LED is lit on the opener, just key in the new code and press Enter.

Maybe you should try clearing the receiver first by pressing the "learn" button and holding it until the LED either goes out or starts flashing (depends on model). Then try reprogramming. Maybe the little computer is confused.

Did you buy right keypad? To get remotes working, hit LEARN or SMART for 1 second and push remote button. Light should flash. Repeat for each remote orkeypad (If you have the right one).
