• Vital Warning: Be exceptionally mindful near the leading edge of the card where the internal antenna coil is located. Slipping with a knife can sever the fine copper wire, rendering the card entirely useless.

Step 2: Inspecting the Circuit Board

As soon as the plastic shell is split open, gently move out the internal printed circuit board (PCB). Utilize a magnifying glass or a smartphone electronic camera zoomed in to examine the board. Look for:

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

Step 3: Resoldering Faulty Connections

• Heat up a fine-tip soldering iron.
• Use 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 microscopic cracks that are blocking electrical continuity.

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.
