Lock picking is the practice of manipulating the components of a lock to open it without using the original key. This technique often involves tools like tension wrenches and picks, which help to align the internal pins of the lock. While it is commonly associated with locksmithing, it can also be used in criminal activities, making it a controversial skill. Many locksmiths use lock picking as a legitimate method to help people who are locked out of their homes or vehicles. Additionally, some hobbyists and security professionals study lock picking to understand vulnerabilities in security systems and improve lock design.
