Before the mid-1990s, Fiat lorries used basic mechanical keys. These keys relied solely on the physical cut of the blade to align the pins within the ignition barrel. While simple and affordable to replicate, they provided really 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 combination of an electronic transponder chip embedded in the head of the secret. The car's engine control system (ECU) would only allow the car to start if it acknowledged the unique digital signature of that specific chip.

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

Maintenance Tips for Fiat Key Fobs

To extend the lifespan of a Fiat key and avoid the high costs of replacement, proactive maintenance is suggested.
