The correct way to program a remote is to hold the button down on the remote and then press and immediately release the learn button. If this doesn't work your logic board is bad.

Get my garage door opener to lose from the remote?


I had a similar problem, but it ended up being the LED lightbulbs put in the opener to replace the incandescent--the LED bulbs were interfering with the remote signal somehow.
But while troubleshooting, I did learn to reset / reprogram the remote: press the Learn button on the opener, then press and hold the button on your remote. The opener lights should blink. That should reprogram your remote.
If that doesn't work, you might have to erase the codes from the opener memory, I think you need to press and hold the Learn button until the lights blink. But you might want to search how to do it for your specific unit.

Sounds like your receiver has quit working. To program the remotes do this: Press and hold the button on the remote while you press and immediately release the smart/learn button. Do this for each remote. If this doesn't work your logic board is bad.

Try this method for programming. Press and hold the button down on the remote while you press and immediately release the learn button. Do this for each remote.

Have you replaced the battery in the keypad? Try 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.

Post back with your results.

Reprogramming remote openers after changing opening code.


If you have dip switches on the back of the opener then the ones in the remote have to match exactly to recode. If you have a learn button on the back of your unit you need to press the learn button and then press the button on the remote1-3 times depending on the brand of the unit. If this does not work try pressing and holding the learn button and then pressing the remote on the remote. The brand and model number would narrow things down greatly for an accurate answer. Thanks BB

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.

Garage door keypad & remote


You need to sync both. I have a LiftMaster. If you want to change the code on your keypad you need to open up the garage door motor compartment where the light is (mine is in the back). Press the learn button, within 30 seconds enter the new code on your keypad and hold down the enter button for several seconds until the light on the opener blinks to tell you it has learned the code. Test the new code to see if it works. If the new keypad code works, then try the remote. My remote will not work after I reprogram the keypad. If the remote does not work (check battery) then climb back up the ladder and press the learn button on the garage door motor again, press the remote button and hold down until the light blinks again and the opener has learned the new code. This process works when I need to sync my remote and keypad. Good luck, I hope this helps.

Remote has stopped working


Its possible you held the learn button down too long, this will erase all remotes. The best way to fix this is to press the learn button once and the hold down the button on the remote until the lights blink, you will have to do this with all remotes.
hope this helps.
