I have a Craftsman garage door with one working remote. The L-Visor-2 looks identical to the working one. The learn button on the unit is green; the date says 1998 (see pic). This is the right remote, yes?
I did end up erasing all codes and successfully programmed my existing remote by following instructions. The two new ones don’t work though, do not respond to my attempts to program them. The light does not blink and there are no clicks or any other kind of response. Do I have incompatible remotes?
