I'm trying to rekey all my locks to a Porsche key. I got the car with just a VW key that fit the ignition, and no door keys.
My plan was to start with a valet key that worked in one of the steering columns I have, rekey all the locks to it, swap the ignition switches, and then was going to cut a black/master key to match the valet.
I ran into a problem with the ignition key. I didn't know the 70 and 71 switch was different, and the column I had that the valet key worked is late. The early tumbler I have fits a VW style key only — Porsche key doesn't work.
So for what I am looking for, I think I can use just the tumbler in the cylinder I have or if you want to keep it together and sell the whole switch.
I think I'm using the right names for things, but not quite sure..
Here's a pic from Markb's re-keying your locks thread. I'm looking for either the piece on the bottom left or else the 2 pieces on the left together.
