If the digital signature matches what is kept in the lorry’s memory, the engine is enabled to start.
The Evolution of the Fiat CODE System

This system utilizes a “Master Key” (normally red or brown) that is required to set new keys.CODE 2: Introduced in the late 90s, this system moved away from the Master Key. Rather, an unique five-digit electronic code is generally provided on a “Code Card” offered to the first owner.Modern Systems: Contemporary designs like the Fiat 500 Car Key Replacement 500X or 124 Spider use highly encrypted rolling codes that change whenever the lorry is begun, making them considerably harder to bypass or clone without specialized equipment.Types of Fiat Keys
