The art of Lockpicking is used to open locked doors and containers faster and with fewer broken lockpicks.
To lockpick, use (LS) to rotate the lockpick, then (RS) to rotate the lock. The lockpick must be in the correct position to turn the lock, the further you can rotate the lock, the closer the lockpick is to the correct position.
Lock difficulty (Novice to Master) determines how small the correct spot is. The better your skill, the bigger the spot.
