How to approach it
Each button is a line that's high at rest (through a pull-up) and drops to 0 V when pressed. It goes through the button flex, a filter and, on recent models, a level shifter. If the line is always low, there's a short or the flex is stuck pressed; if it doesn't drop when pressed, it's the flex or the switch.
