• Crucial Warning: Be extremely careful near the top edge of the card where the internal antenna coil is positioned. Slipping with a knife can sever the fine copper wire, rendering the card completely ineffective.

Step 2: Inspecting the Circuit Board

As soon as the plastic shell is divided open, gently slide out the internal printed circuit board (PCB). Use a magnifying glass or a smart device camera focused to examine the board. Search for:

• Micro-fractures in the solder joints, particularly 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 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 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.
