General Info: A professional trained locksmith/security professional may do some or all of the following: install locks, deadbolts and other mechanical or electronic locking devices to safeguard homes, businesses, vehicles and other property. Locksmiths also may modify or repair such devices, rekey locks, make duplicate keys or cards, generate or program new keys/cards for locks whose keys/cards have been lost and respond to emergency calls to unlock vehicles, homes and businesses that have been locked accidentally, or whose locks have malfunctioned. Some locksmiths install and service electronic alarm and surveillance systems. Many locksmiths specify, design, provide, install and service a wide range of electronic access control systems and closed circuit television (CCTV) systems. Because of the integration of electronic security systems with computers and networks, some locksmiths maintain security hardware and software for computer systems. When new or replacement locks are required, a locksmith assists the customer in determining the correct types of locks needed based on the security risk/exposure, life safety application and frequency of use. The locksmith installs locks and security devices using manufacturer's templates and/or industry specifications, by cutting or drilling the proper opening in the selected location with small hand and power tools.
