Recognizing the symptoms of a stopping working card can help diagnose whether the problem lies with the car, the battery, or the internal circuitry of the card itself.

- Inspect the Circuit Board: Once split open, examine the board under a magnifying glass.
- Resolder Loose Components: The most frequent internal issue is cracked solder joints on the microswitches or the battery real estate, usually brought on by the card flexing in a back pocket. Use a soldering iron to reflow the solder on these connection points.
