A locksmith is someone who installs, repairs, and makes locks and keys. They shape metal pieces using tools like forges and molds. Locksmiths help people who get locked out of homes, offices, and cars by picking locks or making duplicate keys. While traditional locksmiths work with physical locks and keys, developments in technology mean some locksmiths now work with electronic access systems like keypads and scanners. To become a locksmith one can receive on-the-job training or take vocational courses, and the field is expected to see continued growth in demand.
