Even if you don't note down the order, it's fairly easy to determine by
trial and erorr if yoyu have the right key -- try each pin in the first
hole until you find one that's level with the top of the plug (inner
cylinder), repeat for all the other holes.

Not so easy with the Medeco locks used on RS/6000- they need both the
height of the cut and the angle of the cut to match the key. Not sure
how many keys IBM used, but there are definitely more than 1.
