Step 2: Internal Repairs-- Fixing Solder Joints and Microswitches

If replacing the battery does not resolve the issue, the issue most likely lies within the internal electronic devices. Over years of everyday usage, the microswitches (the physical buttons soldered onto the circuit board) can break loose from the board due to repeated clicking pressure.

Tools Needed for Internal Repair:

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

Step-by-Step Internal Inspection:

1. Open the Fob: Carefully take apart the external plastic shell.
2. Inspect the Circuit Board: Examine the board under a magnifying glass. Look closely at the metal legs of the buttons.
