• Important Warning: Be extremely cautious near the leading edge of the card where the internal antenna coil is situated. Slipping with a knife can sever the great copper wire, rendering the card totally worthless.

Action 2: Inspecting the Circuit Board

As soon as the plastic shell is split open, carefully slide out the internal printed circuit board (PCB). Use a magnifying glass or a mobile phone video camera focused to inspect the board. Try to find:

• Micro-fractures in the solder joints, especially around the IC chip and the internal battery holder.
• Loose elements that wobble when carefully pushed.

Step 3: Resoldering Faulty Connections

• Warm up a fine-tip soldering iron.
• Apply a small quantity of fresh electronic solder flux to the suspect joints.
• Carefully reflow the solder on the weak connections. The objective is to remelt the existing solder to bridge any tiny cracks that are obstructing electrical connection.

Step 4: Testing and Reassembly

• Before gluing the plastic housing back together, take the circuit board out to the car and test it in the card reader.
• If the car recognizes the card and starts the engine, the repair was effective.
• Utilize a small quantity of plastic-safe superglue or epoxy along the outer edges to re-seal the casing. Avoid utilizing excessive glue, as it can seep within and foul the buttons.
