Locksmiths use files, screwdrivers, pliers, tweezers, and electric drills in their work, as well as special tools such as lock picks. They make original and duplicate keys on keycutting machines. To guide them in their work, they refer to manufacturers' manuals that describe the construction and working of various locks. Locksmiths are also found in department and hardware stores. Others maintain large security systems for government agencies, schools, and large industrial plants.
Locksmiths often specialize in one aspect of their trade.
Working conditions vary with the area of specialization. Some Locksmiths drive to emergency jobs which can occur in the evening, on weekends, as well as outdoors in bad weather. Some Locksmiths schedule regular routes to maintain lock systems for industrial clients. Others work only in shops which are usually clean and safe. However, all Locksmiths occasionally work in awkward positions for long periods of time.
