If changing the battery does not fix the issue, the issue likely lies within the internal electronic devices. Over years of day-to-day usage, the microswitches (the physical buttons soldered onto the circuit board) can break loose from the board due to repetitive clicking pressure.

Tools Needed for Internal Repair:

• Precision soldering iron
• Solder wire and flux
• Amplifying glass or jewelry expert's loupe
• Replacement microswitches (if a switch is totally broken)
• Isopropyl alcohol and cotton bud for cleansing
