Lock Picking

Lukas has picked up a new hobby - lock picking. The lock picking community (yes, there is one) has a robust code of ethics and clear boundaries. His first set of locks and tools came courtesy of another member of this international community. Now, whenever Lukas has a spare moment, he picks locks. Noah has also shown an interest, and the two of them compete to see who can pick the lock the fastest. Anyone has a bunch of old locks to donate?
