Locate a working point on the same line (often a test point on the back of the board or a series resistor).
Remove the battery for a few seconds to clear temporary software glitches that might make buttons seem unresponsive.
Solder one end of the wire to the source and the other to the non-functional button pad.
When a track is physically broken, you must bypass the damage with a "jumper"—a thin insulated copper wire.
Use isopropyl alcohol to remove oxidation from the button pads.
Before performing hardware repairs, try these simpler solutions:
Failed series resistors or capacitors along the keypad lines can disrupt the signal.
