Lock picking is the art of unlocking a lock by analyzing and manipulating the components of the lock device without the original key. It takes lot of trial and error. The key to a lock that cannot be picked is finding a lock that is unique and rare. In normal situations, it is almost always easier to gain access by some means other than lock picking. Most common locks can be quickly and easily opened using a drill, bolt cutters, padlock shim, a bump key, or a hydraulic jack.
