In the mid-1990s, Fiat presented the "Code" system. These keys included a little transponder chip hidden inside the plastic head.

Most modern-day Fiats, such as the Grande Punto and the 500, utilize a flip-style key. These integrate a transponder chip with a remote-control circuit board for locking and unlocking doors.
4. Smart/Keyless Entry Keys
The current Fiat models, especially the 500e and high-spec 500X models, make use of distance sensors. These keys permit the chauffeur to open and begin the car without ever removing the gadget from their pocket or bag.
