1. Mechanical Keys (Pre-1995)

Before the mid-1990s, Fiat vehicles utilized standard mechanical keys. These keys relied entirely on the physical cut of the blade to align the pins within the ignition barrel. While easy and affordable to duplicate, they provided very little security against "hotwiring" or required entry.

2. The Fiat Code System (1995-- Present)

In 1995, Fiat introduced the "Fiat Code" system. This marked the integration of an electronic transponder chip embedded in the head of the secret. The automobile's engine control unit (ECU) would just allow the car to start if it recognized the unique digital signature of that specific chip.

• Case Damage: The plastic housings typically split, which can lead to the internal circuit board being exposed to wetness or dust.
