I spent a whole afternoon with my friend... we talked about all the improvement ideas for his company locks.
He was quite unsure about the possibility to develop some ideas but he reported all of them to his boss.
They decided to start with the less complex ones: they'll change the springs and pins on some locks and then we'll test them together.
The same day he gave me a "toy" I suggested him to buy from our sponsor (lockpickshop).

Since now I had no luck with this tool... it's a lot heavier and bigger than the tools I use (you can see them on the left in the first picture).
Anyway I just watched the video that comes with the tool and now I'm ready to give it another try. I have to give it back to him soon but I guess I can play with it for a couple of weeks
I'll keep you updated.
Cheers
