Over the years, Renault has actually evolved this technology across various generations of the Megane:

• Megane Mk2 (2002– 2008): Introduced the timeless slot-in key card. Some variations needed insertion into the control panel dash slot, while “Hands-Free” variants allowed the chauffeur to keep the card in a pocket or bag.
• Megane Mk3 (2008– 2016): Refined the style with more long lasting plastics and enhanced distance sensing units for hands-free locking and unlocking.
• Megane Mk4 (2016– Present): Features modern, elegant cards geared up with sophisticated rolling-code security and full hands-free performance.

2. Physical Damage: Sitting on the card, dropping it repeatedly, or exposing it to moisture can crack the internal circuit board or break the fragile solder joints linking the internal antenna.
3. Desynchronization: Occasionally, the card loses its sync with the lorry’s computer due to strong electro-magnetic interference or a completely dead car battery.
4. Internal Chip Failure: The RFID transponder chip– responsible for the immobiliser handshake– can break down or stop working in time, avoiding the car from beginning even if the doors unlock.
