If the light in the wall control is flashing press and hold the lock button for 3 seconds. Your remote should now work.

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.

The correct keypad for your opener is 139.53684. The 53876 keypad is an older technology and will not work correctly. If you program it you will find your remotes no longer work and if you reprogram your remotes the keypad will not 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.

First, check the springs in the actual door to make sure that they are not broke. Since you held the learn button down to reset the opener, you have to reprogram all of your remotes. This button only resets the remotes. It has nothing to do with the rest of the opener. To reset the opener, simply unplug it for a couple of minutes and then plug back in. Pull the handle on the door and see if you can operate the door manually with one hand. If it takes more than 15lbs to move the door, there is a problem with the door balance. If the springs are not broke and the door operates smoothly, the likely cause is the rpm sensor on the opener.

easyer then that , you die! Open your garage door, take out the step ladder, a chair or get up on *********** in law's back, (here's your chance to be on her back for a change) press the read button of your unit (motor) a led should light up and on the key pad, key in the new 4 digits code and press enter, the light of the unit should blink javascript:; Post Solution
