How do you remove an ignition barrel from a Honda jazz as key has stopped turning?

To remove the ignition barrel from a Honda Jazz when the key won't turn, first ensure the steering wheel isn't locked. Then, disconnect the car battery to avoid any electrical issues. Locate the release pin or screw on the ignition housing, usually found underneath or to the side. Insert a small tool to press the pin while turning the barrel slightly to pull it out. If the barrel is jammed, you may need to drill the lock or consult a professional for assistance.
