The Fiat Code 1 System (1995-- 1998)
Fiat was one of the very first makers to introduce the “immobilizer” system, referred to as Fiat Scudo Key Programming Code. The very first generation (Code 1) used a fixed-code transponder chip embedded in the plastic head of the key. When the key was inserted into the ignition, the car’s ECU (Engine Control Unit) would read the code. If it matched, the car started.
The Fiat Code 2 and Code 3 Systems (1998-- Present)

Unlike Code 1, where the signal remains the same, Code 2 and 3 systems alter the digital code whenever the secret is utilized. This makes “cloning” a key significantly harder and needs specialized diagnostic devices for programming.
