So, I've been repinning a whole bunch of locks for a workshop I'm giving tonight and I pulled a couple Yale deadbolts out of my box o' locks. One is a 5 pin and the other a 6, and both are just common deadbolt cylinders. Something common to both of these, but something I've not seen before, is that all the key pins are rounded on both ends. Presumably, this is done to account for tolerance issues, but it seems to me Yale is normally a decent brand, and the keyways are a bit more on the restrictive side, so I was surprised to see this in these particular locks. If I saw this in some no-name lock it would not have been surprising, but in a Yale?
So, my question to those of you more familiar with Yale locks. Is this common? Both locks appear to be fairly old, and came to me in a bulk ebay purchase of assorted salvaged locks.
