Yes, most likely which is much easier to fix than a bad cord. You can peel off the tape holding down the dome and bridge the contact briefly with something conductive and see if you get a button press. If so, you can clean up the area and the dome with rubbing alcohol and once dried use a fresh piece of tape to reapply the dome. If the dome is damaged, like split or crushed than you will need to replace it, you can salvage one from a joystick control if needed.
