The Fiat CODE System
The Fiat CODE system was a revolutionary action in automobile immobilizer innovation. It operates through a little transponder chip embedded in the head of the key. When the secret is inserted into the ignition, an inductive coil around the barrel reads the special digital code from the chip. If the code matches the one kept in the vehicle's Body Control Unit (BCU), the engine is enabled to start.
Stage 1 (Fixed Code): Used in the late 90s, these keys had a fixed code. While more secure than mechanical keys, they were prone to being copied.Stage 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 burglars to intercept and duplicate the signal.Types of Fiat Car Keys
Depending upon the model and year of manufacture, a Fiat chauffeur might have among several different kinds of keys. Each serves a particular functional and security purpose.
1. Standard Transponder Keys
