In the early variations (discovered in designs like the older Punto or Bravo), the system used a "Master Key" (usually maroon or brown) and a number of "Slave Keys" (blue). The Master Key was needed to set brand-new keys into the system. If the Master Key was lost, changing the entire ECU and lock set was typically the only service.
Fiat Code Phase 2 and Beyond
Modern Fiats utilize a "Rolling Code" system. Every time the key is utilized, the code changes based upon an algorithm shared between the secret's transponder chip and the car's BCM. This makes "cloning" keys significantly more tough and demands specialized diagnostic equipment for programming.
Kinds Of Fiat Keys and Their Features
