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 fixed code. While safer than mechanical keys, they were vulnerable to being copied.
- Stage 2 (Rolling Code): Introduced in the early 2000s, this system creates a new code each time the key is utilized, making it nearly difficult for burglars to obstruct and replicate the signal.
Kinds Of Fiat Car Keys
Depending on the design and year of manufacture, a Fiat motorist might have one of numerous different kinds of keys. Each serves a specific practical and security purpose.
