I think when you programmed the two remotes you may have changed the program code so the keypad didn’t work. The keypad is simply a remote (radio signal) that is activated by pressing the correct combination. Don’t know which model opener you have, but for most you press and hold the “smart” learning button on the opener until the light blinks, then operate the remote. In this case, use the keypad while in the learning mode. On some units, to add a remote you press and hold the light button on the indoor controller. Check back with a model number, or just follow instructions for adding a remote.
