Yes, I did check the batteries in both remotes and replaced them just in case, even though I had just bought one of the remotes brand new last year, and replaced the batteries in the older remote at the same time, so they both had new batteries as of June of last year and were not even used very much since then.
I also forgot to mention that the wireless keypad just outside of the garage door also does not open the door, even though it lights up when I press the buttons to put the code in.
Yes, I had tried reprogramming the remotes using the manual, and this is where I'm having problems. After following the procedures using both the wall console (I do have the premium console) and the SRT button on the opener itself, the reprogramming doesn't work. The manual states that the light on the opener will flash once to indicate that the reprogramming was successful, but this doesn't happen. I'm guessing it's a problem with the logic board, but wasn't sure if there was something else I was missing.
