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

If changing the battery does not resolve the problem, the issue likely lies within the internal electronic devices. Over years of daily use, 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
• Amplifying glass or jewelry expert's loupe
• Replacement microswitches (if a switch is entirely broken)
• Isopropyl alcohol and cotton bud for cleaning

Step-by-Step Internal Inspection:

1. Open the Fob: Carefully dismantle the outer plastic shell.
2. Inspect the Circuit Board: Examine the board under a magnifying glass. Look carefully at the metal legs of the buttons.
3. Identify Cold Solder Joints: If a switch moves a little when nudged with a toothpick, the solder has split.
4. Reflow the Solder: Using a heated soldering iron, touch a little dab of fresh solder to the connection points to re-establish electrical connection.
