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

Many modern 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 opening doors.
4. Smart/Keyless Entry Keys
The most recent Fiat models, particularly the 500e and high-spec 500X models, use distance sensing units. These keys permit the driver to open and start the car without ever removing the gadget from their pocket or bag.
