Action 2: Test the Card in the Slot (If Applicable)

If the lorry has a physical card slot on the control panel, attempt inserting the card by hand.

• Superglue or plastic welding adhesive

The Repair Process:

1. Open the Casing: Carefully score along the glued joint of the plastic card using a pastime knife. Warning: Be incredibly mindful not to cut too deep, as the internal circuit board sits really near the external edge.
2. Inspect the Circuit Board: Once split open, examine the board under a magnifying glass.
3. Resolder Loose Components: The most regular internal problem is split solder joints on the microswitches or the battery real estate, typically caused by the card flexing in a back pocket. Use a soldering iron to reflow the solder on these connection points.
4. Check the RFID Coil: Look closely at the fine copper wire running around the border of the board. If this wire is snapped, the car will never recognize the card. Re-joining microscopic copper wire is exceptionally challenging and usually needs expert micro-soldering.
