Papaiz may be a european company that moved to brazil for the cheap labor and local market. I think I read this about them somewhere.
nkt mentions that the lock has to be repicked, sort of like a manually picked ace lock will relock every eighth of a turn. I think we should think of a simple solution to this sort of thing that will hold pins in position, I have never owned or successfully used a plug spinner (all I can remember trying is the rubberband and tension wrench combination) but there must be a simple way of doing it. if a type of shim could be introduced into the bottom of a keyway and worked around the plug to the pins, but does papaiz even have an open bottom keyway, I don't have one here to look at but I don't think so well thats just speculation. Ive got nothing.
