Why Do Renault Megane Cardkeys Fail?

- Cracked Solder Joints: The internal elements are soldered to the circuit board. Flexing the card triggers these tiny solder points to fracture, breaking the electrical connection.

- Battery Exhaustion: The internal battery (typically a CR2032 or CR2016 cell) ultimately dies, cutting power to the transponder and remote transmitter.
- Environmental Damage: Exposure to moisture, severe heat, or being dropped on difficult surfaces can permanently damage the sensitive electronics within.
