How do you change an ignition barrel on a Fiesta Mk 3?

Oh, dude, changing the ignition barrel on a Fiesta Mk 3 is like, super easy. First, disconnect the battery, remove the steering wheel, and then you just gotta unscrew the old ignition barrel and pop in the new one. Just make sure you don't accidentally set off the airbag while you're at it. Easy peasy, lemon squeezy!
