I just got a cheap lock to let my friend try bumping, on the key it says "duration" Ive never herad of it and want blanks for it. It has almost a yale keyway but not quite any advice? (sorry scanner died)

Take a look in the Ilco key catalog online and match up your keyway. You should be able to determine which blank it is that way. Without a picture, it's very hard to determine what kind of blank it is.

Alternately, you could just go to the hardware store and have the key copied. Then it falls to the person copying the key to determine which blank it is, and then you can make bump keys from the copied keys, as the spacing would be apparent from the cuts already made in the key.

Regarding above suggestion I agree that without image its hard to tell exactly the kind of blank. But you may compare with online catalog. One of my fried also brought a blank and compared that and find what exactly what is it.
