- Clip the battery cover back into place and re-insert the emergency situation key. Pointer: Avoid touching the flat surface areas of the new battery
- with bare fingers; the oils from skin can prevent electrical conductivity. Use a fabric or plastic tweezers if possible. Advanced Repairs: Fixing Internal Circuitry and Micro-Switches If replacing the battery does not fix the problem, the issue likely lies within the internal circuit board. Renault key cards, in particular, withstand a great deal of stress when sat on in back
- pockets, resulting in cracked solder joints. Tools Needed for Circuit Board Repair: Precision soldering iron Amplifying glass or jeweler's loupe Plastic opening tool (spudger) Replacement micro-switches( if buttons are broken) Isopropyl alcohol and a cotton bud Fixing CrackedSolder Joints Over years of use, the small solder joints connecting the internal
elements-- such as the battery housing, the transponder chip, or the induction coil-- can crack due to flexing. Open the Casing: Carefully pry open the key card casing. Due to the fact that Renault key cards are normally ultrasonically bonded shut, this needs persistence. Utilize a plastic tool to prevent harming the internal
- board. Inspect Under Magnification: Use a magnifying glass to examine the circuit board. Look for dull, broken, or ringed solder joints(particularly around the battery terminals and the big copper antenna coil). Resolder Connections: Using a fine-tip soldering iron, thoroughly reflow the solder on
any suspicious connections. Include a tiny dab of fresh solder if required to ensure a solid electrical bond. Clean the Board: Wipe away any particles or old flux with isopropyl alcohol.
