Found in older designs from the 1980s and early 1990s, these keys were simple metal blades without electronic parts. While they provided low security, they were low-cost to duplicate.
2. The Fiat Code System (First Generation)
In the mid-1990s, Fiat presented the "Code" system. These keys included a small 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 new keys to the system.

A lot of contemporary Fiats, such as the Grande Punto and the 500, use a flip-style secret. These combine a transponder chip with a remote-control circuit board for locking and opening doors.
4. Smart/Keyless Entry Keys
The newest Fiat Replacement Car Keys designs, especially the 500e and high-spec 500X designs, make use of proximity sensors. These keys enable the motorist to open and start the car without ever getting rid of the device from their pocket or bag.
