When the key is inserted 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.
Phase 1 (Fixed Code): Used in the late 90s, these keys had a fixed code. While much safer than mechanical keys, they were vulnerable to being copied.Stage 2 (Rolling Code): Introduced in the early 2000s, this system produces a new code every time the secret is used, making it nearly difficult for burglars to intercept and replicate the signal.Types of Fiat Car Keys

Historically, when a Fiat was purchased brand-new, it came with a blue or white "Code Card." This card included an electronic code (a 5-digit pin) and a mechanical code.
Electronic Code: Necessary for programming new keys into the immobilizer system.Mechanical Code: Provides the "cut pattern" for the metal blade.
