When the key is placed into the ignition, an inductive coil around the barrel reads the distinct digital code from the chip. If the code matches the one kept in the automobile's Body Control Unit (BCU), the engine is permitted to begin.
Stage 1 (Fixed Code): Used in the late 90s, these keys had a fixed code. While more secure than mechanical keys, they were susceptible to being copied.Stage 2 (Rolling Code): Introduced in the early 2000s, this system generates a new code whenever the secret is utilized, making it almost impossible for thieves to intercept and reproduce the signal.Kinds Of Fiat Car Keys
