• Important Warning: Be extremely mindful near the leading edge of the card where the internal antenna coil is situated. Slipping with a knife can sever the fine copper wire, rendering the card entirely ineffective.

Action 2: Inspecting the Circuit Board

When the plastic shell is split open, gently move out the internal printed circuit board (PCB). Use a magnifying glass or a mobile phone video 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 parts that wobble when carefully pushed.

Action 3: Resoldering Faulty Connections

• Warm up a fine-tip soldering iron.
• Use a tiny 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 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.
