It's been a year since my original 328 was totaled - completely forgot it's the same key...which is still the same key I don't have Assume I'll need a locksmith to come out and pattern the lock cut a new key.
The door and louvre key are the same. You might contact Ferrari with your VIN and get a new one. Not the same as the ignition key which has bitting only on one side. Two bitting sides on the door and louvre key.
