| Part | Function | Typical Failure Mode |
|---|---|---|
| CR2032 Battery | Powers the remote locking and hands-free transponder signals. | Loss of variety, total remote failure. |
| Internal Microswitch | Signs up physical clicks of the lock/unlock buttons. | Solder joints fracture; buttons stop clicking or responding. |
| RFID Transponder Chip | Interacts with the car's immobilizer to permit engine start. | Chip cracks or disconnects from the board (frequently causes "Card Not Detected" errors). |
| Induction Coil | Charges the battery (in some variations) and functions as an emergency situation backup receiver. | Wire breaks due to card bending. |
Typical Mégane Card Key Issues and Symptoms
