This older design includes a physical key blade that must be inserted into the ignition cylinder. The plastic bow of the key houses buttons for locking and opening the doors by means of radio frequency.

Renault Mégane key cards and remotes undergo everyday wear and tear. Because of their distinct flat shape, they are also prone to specific types of damage.

  • Micro-cracks on the internal circuit board triggered by the card being rested on in a back pocket.
  • Failure of the internal receiver coil within the lorry's card reader.
• Buttons Unresponsive: Over time, the tactile micro-switches soldered onto the internal circuit board can separate or wear, suggesting presses are no longer signed up by the car.
