Open the Casing: Carefully pry open the key card case. Since Renault key cards are usually ultrasonically welded shut, this requires perseverance. Utilize a plastic tool to avoid harming the internal
- board. Inspect Under Magnification: Use a magnifying glass to check the circuit board. Try to find dull, split, or ringed solder joints(specifically around the battery terminals and the large copper antenna coil). Resolder Connections: Using a fine-tip soldering iron, thoroughly reflow the solder on
any suspicious connections. Add a small dab of fresh solder if necessary to guarantee a solid electrical bond. Clean the Board: Wipe away any particles or old flux with isopropyl alcohol.
