Today, the contemporary [Fiat Replacement Car Keys](https://bookmarkstime.com/story21457962/why-adding-a-fiat-500-electric-key-to-your-life-can-make-all-the-different) 500 includes advanced transponder chips and rolling codes to avoid theft.

Standard Remote Flip Key: The most common range, including three buttons (Lock, Unlock, and Boot Release/Trunk).

Fiat makes use of a security procedure referred to as the Fiat Code System. Inside every modern-day secret is a transponder chip. When the key is placed into the ignition or the distance sensor is activated, the car's Body Control Unit (BCU) sends out an electro-magnetic pulse to the key. The key reacts with a special alphanumeric code. If the code matches the one kept in the car's memory, the engine immobilizer is shut off.

The "Blue Key" Mystery: On older Fiat designs produced in the late 90s and early 2000s, owners were frequently supplied with a "Blue Key" and a "Red Master Key." The Red Key was important for programming brand-new keys into the system. In the existing Fiat 500 (2007 onwards), this system has been changed by a digital code card that contains a 5-digit electronic security code.

Sometimes, if the car battery or the essential battery dies entirely, the key may lose its synchronization with the immobilizer. This results in the "Car with Lock" symbol appearing on the control panel, preventing the engine from starting.
