This chip, referred to as a transponder, interacts with the lorry's Engine Control Unit (ECU). When the key is placed into the ignition (or brought near the start button), the ECU sends out a signal to the secret. If the digital signature matches what is saved in the lorry's memory, the engine is allowed to begin.
The Evolution of the Fiat CODE System
Fiat uses various generations of its security system, typically described as Fiat Key Duplication CODE.
CODE 1 (Rolling Code): Found in earlier models like the Punto Mark 1. This system utilizes a "Master Key" (generally red or brown) that is needed to program brand-new keys.CODE 2: Introduced in the late 90s, this system moved far from the Master Key. Instead, an unique five-digit electronic code is normally supplied on a "Code Card" provided to the first owner.Modern Systems: Contemporary designs like the Fiat 500X or 124 Spider usage extremely encrypted rolling codes that change every time the lorry is started, making them significantly harder to bypass or clone without specific equipment.Kinds Of Fiat Keys

If a working key is present, a locksmith or dealer can use a laser-cutting maker to replicate the physical grooves. If all keys are lost, the locksmith should "decipher" the lock cylinder or get the mechanical key code from Fiat's database to cut a new blade from scratch.
2. Software application Programming
This is the most important action. A specialized diagnostic tool is plugged into the lorry's OBD-II port. The technician should delete any lost keys from the automobile's memory (for security) and sync the new transponder chip to the ECU. For Fiat lorries, this often needs the 5-digit security PIN.

Owners of vintage Fiats (late 90s) need to be especially cautious. These cars and trucks were sold with one Red/Brown Master Key and 2 blue servant keys. The system was created so that the Master Key was the only tool efficient in opening the "shows window" in the ECU.
