Snap the casing back together securely. For Key Cards
(Megane II, III, & IV): Locate the little release button or slide mechanism on the edge ofthe card to pull out the emergency situation metal physical
- key. Look inside the emergency situation key slot for a small plastic tab.
- Utilize the idea of the physical key or a little tool to carefully pop off

- Clip the battery cover back into place and re-insert the emergency key. Idea: Avoid touching the flat surfaces of the brand-New Key For Renault Trafic battery
- with bare fingers; the oils from skin can impede electrical conductivity. Utilize a cloth or plastic tweezers if possible. Advanced Repairs: Fixing Internal Circuitry and Micro-Switches If replacing the battery does not fix the problem, the problem most likely lies within the internal circuit board. Renault key cards, in specific, withstand a lot of stress when sat on in back
- pockets, leading to 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 swab Repairing CrackedSolder Joints Over years of usage, the small solder joints connecting the internal
components-- such as the battery housing, the transponder chip, or the induction coil-- can split due to flexing. Open the Casing: Carefully pry open the key card case. Due to the fact that Renault key cards are normally ultrasonically bonded shut, this requires perseverance. Use a plastic tool to prevent 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(especially 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 needed to make sure a strong electrical bond. Tidy the Board: Wipe away any particles or old flux with isopropyl alcohol.
- Test Before Sealing: Test the card in the car before gluing the plastic real estate back together.
