Common Problems with Renault Keys

Physical Damage: Because slot-in cards are typically kept in back pockets, they are vulnerable to snapping or splitting when chauffeurs sit down. This can damage the internal copper coils and microchips.
Desynchronisation: Occasionally, the rolling security code in between the key and the automobile can end up being out of sync. This leaves the motorist unable to unlock the doors from another location, even with a fresh battery.
Ignition Slot Failures: For models that require the card to be inserted into a dash slot, dust and debris can collect inside the mechanism, preventing the car from signing up that the card is present.
