- Clip the battery cover back into location and re-insert the emergency key. Pointer: Avoid touching the flat surfaces of the new battery
- with bare fingers; the oils from skin can prevent electrical conductivity. Use a fabric or plastic tweezers if possible.

Renault key cards, in specific, withstand a lot of stress when rested 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 Fixing CrackedSolder Joints Over years of usage, the small solder joints connecting the internal
