Translating the Fiat Code System

Fiat makes use of a security protocol Fiat Ducato Key understood as the Fiat Code System. Inside every modern-day key is a transponder chip. When the secret is placed into the ignition or the proximity sensing unit is triggered, the car's Body Control Unit (BCU) sends an electro-magnetic pulse to the key. The essential reacts with a distinct alphanumeric code. If the code matches the one stored in the car's memory, the engine immobilizer is shut off.

3. Button Wear

The rubberized buttons on Fiat 500 keys are susceptible to destruction. Regular use can result in the rubber tearing or falling out, exposing the micro-switches beneath to wetness and particles, which eventually causes circuit board failure.
