Before the mid-1990s, Fiat cars used basic mechanical keys. These keys relied solely on the physical cut of the blade to line up the pins within the ignition barrel. While easy and inexpensive to replicate, they provided very little security versus "hotwiring" or forced entry.

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

In 1995, Fiat presented the "Fiat Code" system. This marked the combination of an electronic transponder chip embedded in the head of the secret. The car's engine control system (ECU) would just permit the car to begin if it acknowledged the unique digital signature of that particular chip.

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