2002 to present (Mk6, Mk7, Mk8). Ford 6000CD, Sony CD/DAB, SYNC 1
Does a Mk8 Fiesta need a radio code? Generally no. SYNC 3 systems are tied to the vehicle rather than protected with a four-digit audio code, so a flat battery does not lock them out.
My Fiesta shows LOCKED after a jump start Too many wrong attempts have been made. Leave the ignition on with the radio powered for 30–60 minutes and it should return to the CODE prompt.
Can I get the code from the Fiesta's registration? No. Ford codes belong to the head unit serial, not the car.
