• Vital Warning: Be incredibly careful near the top edge of the card where the internal antenna coil is located. Slipping with a knife can sever the great copper wire, rendering the card entirely worthless.

Action 2: Inspecting the Circuit Board

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

• Micro-fractures in the solder joints, particularly around the IC chip and the internal battery holder.
• Loose components that wobble when gently nudged.

Step 3: Resoldering Faulty Connections

• Warm up a fine-tip soldering iron.
• Apply a tiny amount 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 microscopic cracks that are blocking electrical continuity.

Step 4: Testing and Reassembly

• Before gluing the plastic case back together, take the circuit board out to the car and test it in the card reader.
