Secondly, I am quiet sure this has been designed before, but I want to put it here in case it hasnt.
So here it goes:

The idea was quiet simple - every time a lock completes revolution and driver pins meet the bottom pins, the pins reset and you have to pick it again. Therefore if we add more driver pins, (i would reccomend eight times more, I was only able to draw four, but anyways) the pins reset many times, meaning the picker has to pick it more times to complete one full revolution. That wouldnt make picking harder, but slower, and the picker would have a bigger chance of being spotted.
Hopes this is understandable, not completely dumb and helps.
