It works flawlessly every time but I KNOW how much of a punk those things can be to have to fix if they don't rotate.
I need a new ignition key anyway...mine is flunky and short (PO lost the rubber part).

Is a 81 300SD supposed to have a non-high security key for the ignition? Cause mine isn't...(doors are though)
