Advanced Repairs: Fixing Internal Circuitry and Micro-Switches If changing the battery does not deal with the problem, the problem likely lies within the internal circuit board. Renault key cards, in particular, endure a lot of stress when rested on in back
- pockets, resulting in split solder joints. Tools Needed for Circuit Board Repair: Precision soldering iron Magnifying glass or jeweler's loupe Plastic opening tool (spudger) Replacement micro-switches( if buttons are broken) Isopropyl alcohol and a cotton swab Fixing CrackedSolder Joints Over years of usage, the small solder joints connecting the internal
elements-- such as the battery real estate, the transponder chip, or the induction coil-- can crack due to flexing. 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. Check Under Magnification: Use a magnifying glass to check the circuit board. Search for dull, cracked, 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. Include a tiny dab of fresh solder if essential to ensure a strong electrical bond. Clean the Board: Wipe away any debris or old flux with isopropyl alcohol.
