If your other remotes work okay your keypad has just failed. Time for a replacement.

My wireless keypad stopped working. I replaced the battery. It worked 1x and hasn't worked since. I'm able to program remotes. The keypad is backlit and flashes when I enter the code or try to program it....


I would make sure the battery contacts are clean and not corroded. Otherwise a new keypad is most likely the answer. Just FYI the keypad will still work when the wall control is locked.

Garage door opener keypad stopped working. cannot reprogram it.


It could just be you need to replace the battery.
The warning light might be a "battery low" warning - advising you to replace it!
If it stops flashing, the battery has died altogether.

I have a Chamberlain opener and it uses CR2032


Something in your remote is using power all the time. You need to replace it.
