• Crucial Warning: Be exceptionally cautious near the top edge of the card where the internal antenna coil is located. Slipping with a knife can sever the fine copper wire, rendering the card totally worthless.

Action 2: Inspecting the Circuit Board

When the plastic shell is split open, gently slide out the internal printed circuit board (PCB). Utilize a magnifying glass or a smart device camera focused to inspect the board. Search for:

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

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.
• Thoroughly reflow the solder on the weak connections. The goal is to remelt the existing solder to bridge any tiny fractures that are obstructing electrical connection.

Step 4: Testing and Reassembly

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