If the code matches the one stored in the car's Body Control Unit (BCU), the engine is allowed to start.
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.Stage 2 (Rolling Code): Introduced in the early 2000s, this system generates a new code every time the key is used, making it nearly impossible for thieves to obstruct and replicate the signal.Types of Fiat Car Keys
