A locksmith is a professional who works with locks on doors, windows,
safes, cars, etc. Locksmiths install, repair, and adjust locks in
everything from cars to office buildings, and they also offer services
to people who are locked out or individuals who want to consult with
someone about their security systems. This profession is quite ancient;
as long as there have been locks and keys to fit them, there have been
people who specialize in them. Supervise and participate in installation, repair and maintenance of locks, door closures, electronic locking systems and panic hardware systems; supervise the recombination and adjustment of locks including coding, key cutting and duplication. Their skill and knowledge in installing and repairing conventional
security hardware and locksets take them to work in residential,
commercial and industrial establishments that require varying levels of
physical security to protection them from unauthorized entry.
