Since Renault key cards are typically ultrasonically bonded shut, this requires perseverance. Use a plastic tool to avoid harming the internal
- board. Inspect Under Magnification: Use a magnifying glass to examine the circuit board. Search for dull, split, or ringed solder joints(particularly 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. Include a small dab of fresh solder if required to make sure a strong electrical bond. Clean the Board: Wipe away any particles or old flux with isopropyl alcohol.
