Unlike the repaired code, the rolling code changes each time the car is begun, making it substantially harder for burglars to bypass the immobilizer via signal "smelling."

The Late Models (Punto Evo and 2012+ Models)

The final generations used sophisticated remote flip keys with incorporated circuits.

Step 2: Programming the Transponder

The brand-new secret should be presented to the car's computer system. There are 2 primary methods this is achieved:

1. OBD2 Programming: A service technician plugs a diagnostic tool into the vehicle's OBD port and "teaches" the car to acknowledge the brand-new crucial ID.
2. Pre-coding/EEPROM: On numerous Fiats, the secret needs to be "pre-coded" utilizing data pulled from the car's BCM (Body Control Module) before it can be ended up via the OBD port.
