Because Renault key cards are usually ultrasonically bonded shut, this requires patience. Use a plastic tool to avoid damaging the internal
- board. Examine Under Magnification: Use a magnifying glass to check the circuit board. Look for dull, split, or ringed solder joints(specifically around the battery terminals and the big copper antenna coil). Resolder Connections: Using a fine-tip soldering iron, carefully reflow the solder on
any suspicious connections. Add a tiny dab of fresh solder if needed to ensure a strong electrical bond. Clean the Board: Wipe away any debris or old flux with isopropyl alcohol.
