I want to go get a key double-cut. Does anybody remember which side of the key the lock uses? I have one key that's already double cut and I want to make sure I copy the correct side. So in other words, does the steering column use the top or bottom of the key? For those of you unfamiliar with double-cutting, what it means is if you have two fords of our vintage, you can put both trucks on one key, because only one side is used. You just put the key in one way for one truck, and the other way for the other one. I usually cut a notch in the handle to remember notch up or notch down depending on the vehicle I want to get in.
