You don't have to cut the lock face out...that's a waste of time...all I had to do with the dremel was to ground down the popout locating pin on the ignition housing then the entire housing slid right out from the steering column. Once you get your new housing with new lock cylinder and black cap together, you turn the key to the first notch, the popout will retract and you can slid the whole deal back onto the steering column....let the popout pin pop out and lock it all together with the clamp and reassemble the lower panel....and you're done!!
