If the code matches the one kept in the car's Body Control Unit (BCU), the engine is permitted to begin.
Stage 1 (Fixed Code): Used in the late 90s, these keys had a static code. While safer than mechanical keys, they were vulnerable to being copied.Phase 2 (Rolling Code): Introduced in the early 2000s, this system produces a new code each time the key is used, making it almost difficult for thieves to intercept and reproduce the signal.Kinds Of Fiat Car Keys

Electronic Code: Necessary for configuring brand-new keys into the immobilizer system.Mechanical Code: Provides the "cut pattern" for the metal blade.
