2. Worn or Damaged Buttons
With time, the rubber pads on the key fob can wear down or end up being misaligned. If the internal tactile turn on the PCB isn't being compressed properly, the remote will fail to send out a signal.
3. Internal Component Damage
Dropping a key fob can trigger tiny fractures in the PCB or break the solder joints that hold the battery terminal or buttons in place. Likewise, exposure to water can trigger short circuits or deterioration.
