If the code matches the one stored in the car's Body Control Unit (BCU), the engine is allowed to begin.
Phase 1 (Fixed Code): Used in the late 90s, these keys had a static code. While more secure than mechanical keys, they were prone to being copied.Phase 2 (Rolling Code): Introduced in the early 2000s, this system produces a brand-new code every time the secret is utilized, making it almost impossible for thieves to obstruct and reproduce the signal.Types of Fiat Car Keys
