Utilized primarily in older designs (pre-1995), these keys are simple metal blades with no internal electronic devices. They operate the mechanical locks and the ignition cylinder through physical wafers.
2. Transponder Keys (Fiat Code System)
Introduced in the mid-90s, the "Fiat Key Cutting Code" system added a layer of security. These keys include a small transponder chip embedded in the plastic head. When the secret is inserted into the ignition, the car's immobilizer system sends out a signal to the chip. If the chip's unique code matches the car's configured data, the engine starts.

Replacing a modern Fiat key is not as easy as cutting a piece of metal. It includes an advanced three-step process.
