I had a Model A that both the ignition and door keys did not have a readily available blank. None of the blanks sold by the vendors were correct. I took it to my friendly local locksmith who took this as a challenge. He found a couple of blanks that at least had the grooves properly cut, adjusted the shoulder and length to fit, then cut the pattern. Took him a bit but in the end we were both satisfied. Not your standard guy in the kiosk at the mall, this guy was a real old school pro.
