Fuji FinePix Model S3280 left button does not work, cannot do setup

I have TWO Fuji FinePix Model S3280 cameras that I love. I used the first one for over 7 years and suddenly the left arrow button froze up. I can take photos but I cannot use any of the menu functions in set up such as reformat the disk. So I bought another one, same model, that was in new condition. After only a month of use, this camera is doing the SAME thing. The left arrow key will not function and I cannot access anything in setup mode. I have found nothing online. Is this a mechanical issue inside the camera that I can fix or is there a reset option? (Note, there is no option in the pull down menu for S3280, but S4200 is similar. THANK YOU.
