Unlike the repaired code, the rolling code changes each time the car is begun, making it considerably harder for burglars to bypass the immobilizer through signal "sniffing."
The Late Models (Punto Evo and 2012+ Models)
The final generations employed sophisticated remote flip keys with incorporated circuits. These keys manage not only the engine immobilizer however also provide remote main locking, boot release, and alarm activation.
