Locks that work

I thought having really slick, lubricated locks would make it easier to pick/bump...

I assume that lock lube coats the lock parts in a thin layer of graphite, which would protect them, but mainly it's for lubrication.

Even GT85 should be better than WD40. GT85 contains PTFE. The lowest friction substance known to man.

Don't think lubrication helps with picking, but when I made a bump key to try it myself, I did find applying WD40 intermediately before bumping a lock made it much more likely to work on the first attempt. The door locks I have have a sleeve around one of the pins which is supposed to bounce up blocking the shear line if bumped. And disc locks such as the Kryptonite aren't vulnerable to bumping of course.
