My 96 needs a new ignition lock cylinder and saw RockAuto has an ACDelco one, but it says it doesn't come with keys? Description says "PART REQUIRES CODING AT GM DEALERSHIP." What exactly does that mean? Will the security light turn on if I replace it? I've already got new blank GM keys sitting around, so it's not the end of the world, but I'm confused as to why it doesn't come with new keys.
