2. The Fiat Code System (First Generation)
In the mid-1990s, Fiat presented the "Code" system. These keys contained a little transponder chip hidden inside the plastic head. When inserted into the ignition, the car's immobilizer sends a signal to the chip; if the codes match, the engine starts. This era was famous for the "Red Master Key," which was needed to set brand-new keys to the system.
3. Remote Flip Keys
Many modern-day Fiats, such as the Grande Punto and the 500, use 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 most recent Fiat models, especially the 500e and high-spec 500X designs, make use of proximity sensors. These keys permit the motorist to open and start the car without ever getting rid of the gadget from their pocket or bag.
