Garage door openers not working. A few days ago all of our remote garage door openers stopped working. It has happened all of a sudden, all transmitters stopped working at the same time. Both my handheld garage door opener transmitter and the one that is built into my car do not work. I thought maybe the transmitters needed to be reprogrammed. I reprogrammed the transmitters but that did not work. The garage door opener still works as it opens when I use the button wired directly to it in the garage. I know for sure that the transmitters are programmed correctly but still don’t work. My garage door opener is a Liftmaster 1/2 HP opener.
The most common reason for a garage door remote transmitter to stop working is a dead battery. However, if ALL the garage door openers stop working at the same time, then most likely the garage door antenna is not attached properly or the garage door opener itself needs to be reset. You can try to simply unplug the garage door opener from the wall for 30 seconds and see if that resets it.
Here is what to check when all garage door transmitters stop working at same time:
- Be sure nothing (such as a tree hanging over the garage) is blocking the transmitter signal from opening the garage door.
- Test or replace all batteries in handheld remote garage door transmitter(s) and built in car garage door openers.
- Check that the antenna on your garage door opener is securely attached and working.
- Try reprogramming/resetting all remote garage door transmitters.
- If all above test or check good, then reset or reprogram your garage door opener.

I am having the same problem with the remote openers not opening the garage. Saw this about replacing the LED bulbs with incandescent bulbs but that didn’t work either. If I turn off the garage opener lights the remotes work. I tried removing the bulbs, but as long as there was power to the light bulb sockets, the remote wouldn’t work. When the power to the sockets is turned off the remotes work fine. I’m guessing a problem somewhere on the motherboard.
Thank you Jerry and others! Removed my 100W LEDs and our remote openers now work fine again!!
Our outside Garage Door keypad mysteriously stopped working.
We changed internal battery to new 9 volt.
All other remotes and wall switch continued working.
We followed instructions to reprogram/reset keypad and garage door opener.
Lights blinked, etc. and all went as advertised through “the opener has been reset and learned new code”.
Garage door still doesn’t open or close using the keypad.
Suggestions?
I have a Chamberlain Lift Master Professional.
The door closes but opens again straight away once in the closed position without touching the remote Any sujestions?
How do you go about reprogramming three remotes to one opener
I have a Lift Master. The up and down button on the garage and car remote on sunny days only lets the door go down a foot or so and then shoots back up. I have to hold down the remote button on both every time for the door to go down. How do I fix this problem. Hope you have a solution.
Thanks for the insight Jerry and to others who tried the suggestion. I had installed just one LED bulb and both the remotes became erratic. After removing the LED bulb both the remote openers are working fine!!
