Since Renault key cards are generally ultrasonically bonded shut, this requires persistence. Use a plastic tool to prevent harming the internal
- board. Examine Under Magnification: Use a magnifying glass to examine the circuit board. Look for dull, split, or ringed solder joints(particularly around the battery terminals and the large copper antenna coil). Resolder Connections: Using a fine-tip soldering iron, thoroughly reflow the solder on
