Locksmiths have historically been held in high esteem. Their services have been undoubtedly much sought after, from both commercial and residential safety and security fronts. Over time, the trade has experienced tremendous revolution and evolution owing to the emergence of new locking technologies as well as the betterment of existing locking technologies. Historically, locksmiths were famed for producing locks and keys, repairing locks and cutting spare keys. This has since changed. Mass production of locks has made it cheaper to replace the whole lock rather than have it repaired, save for the high-end locks and locks on safe boxes. In other regards, locksmiths have had to contend with the emergence of new locking technologies.
