I think your keypad has just failed. Needs replacing.

That keypad should work with your opener. I suspect the keypad is bad if you have other remotes that work. If not it could be the logic board.

We have a Chamberlain Whisper Drive Plus. The keyless entry stopped working, suddenly. I have changed the battery, not the problem. I cannot get it to work, and cannot get it to reprogram. The keypad lights up when buttons are pressed, but when I press "Enter" the whole keypad flashes for about 30 seconds and then just goes dark.

make sure it is the right keyless entry. For starters, Make sure your antenna hanging off the operator is "purple" color. If it is grey, you have the wrong keyless entry. The keyless you have is for the 315 frequency. If your antenna from the operator is grey, you need to get another keyless entry based on the frequency.

Programming my keyless entry


Yes, you purchased the wrong wireless. You must get a Genie keyless and there are two types of Genie keyless (GWKP & GWK-BL) depending on which Genie operator you have. You might think about a wired keyless entry (Domino GD-1). Then if you change your operator you don't have to change your keyless.
