Dang if youre not too worried you could use this info and key a few pins the same on all your cars and use one key. hell i could go from 20 to 2 .just an ignition and a trunk key. does this work on ignition as well?
It does work on ignition although the cylinder is a bit different in construction and they also differ from column vs dash mount units as to how the cylinders remove from the housings.
