This was the master key utilized to program subsequent "Blue Keys." Losing the Red Key meant that if a new secret was needed, the whole immobilizer system typically needed to be changed-- a notoriously costly endeavor.Rolling Code Systems (Modern Era): Most modern Fiats (post-2000s) utilize a "Rolling Code" system.
