Why Do Renault Megane Cardkeys Fail?

Gradually, this mechanical stress leads to:
- Cracked Solder Joints: The internal elements are soldered to the circuit board. Bending the card triggers these small solder points to fracture, breaking the electrical connection.
- Loose Microswitches: The physical buttons inside the card can detach from the board.
- Battery Exhaustion: The internal battery (generally a CR2032 or CR2016 cell) ultimately dies, cutting power to the transponder and remote transmitter.
- Ecological Damage: Exposure to moisture, severe heat, or being dropped on tough surface areas can completely harm the sensitive electronics within.
