This system was created to prevent the engine from beginning unless a digitally acknowledged secret is present in the ignition.
Fiat Code Phase 1
In the early versions (discovered in models like the older Punto or Bravo), the system used a "Master Key" (usually maroon or brown) and numerous "Slave Keys" (blue). The Master Key was required to program new keys into the system. If the Master Key was lost, changing the whole ECU and lock set was often the only solution.
Fiat Code Phase 2 and Beyond
Modern Fiats utilize a "Rolling Code" system. Every time the key is utilized, the code modifications based upon an algorithm shared in between the secret's transponder chip and the car's BCM. This makes "cloning" keys substantially more tough and requires specialized diagnostic equipment for programming.
