2015 Ferrari 458 lost all keys. While not officially supported with the OBDSTAR X300 Pro4/x300 dp plus, it is identical to the 2007-2012 Maserati Quattroporte. Xtool and Xhorse have done nothing at all other than failing to communicate or read immo on this vehicle.
OBDStar had zero issues. Read immo data, generated key, read PIN, programmed key.
it is true I already to 3 time.
