For the most part, you will be able to interchange the pins from one American cylinder to another with no problem even if the model # is different.
All American locks will have security pins, whether it be Spools, Serrated, Half Serrated, Spooled Serrated or one shaped like an hour-glass (can't think of the technical term at this moment) or a combination of all and the possibility of them being key pins and driver pins.
Every once in a while you will find an American with standard key pins but has security driver pins, or no security pins at all. Those locks have been re-pinned like that for some reason or another. I have come across both scenarios.
