parts-- such as the battery housing, the transponder chip, or the induction coil-- can break due to bending. Open the Casing: Carefully pry open the key card casing. Since Renault key cards are normally ultrasonically welded shut, this requires perseverance. Utilize a plastic tool to avoid damaging the internal
- board. Check Under Magnification: Use a magnifying glass to check the circuit board. Search for dull, broken, 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
