Literature : Locksmithing is the science and art of making and defeating locks. Locksmithing is a traditional trade and in many countries requires completion of an apprenticeship. The level of formal education legally required varies from country to country from none at all, to a simple training certificate awarded by an employer, to a full diploma from an engineering college (such as in Australia), in addition to time spent working as an apprentice.
A lock is a mechanism that secures buildings, rooms, cabinets, objects, or other storage facilities. A smith is a metalworker who shapes metal pieces, often using a forge or mould, into useful objects or to be part of a more complex structure. Thus locksmithing, as its name implies, is the assembly and designing of locks and their respective keys by hand. Most locksmiths use automatic and manual cutting tools to mold keys, most are power tools having battery or mains electricity as their power source.
Locks have been constructed for over 2500 years, initially out of wood and later out of metal.[1] Historically, locksmiths would make the entire lock, working for hours hand cutting screws and doing much file-work. Lock designs became significantly more complicated in the 18th century, and locksmiths often specialized in repairing or designing locks.
After the rise of cheap mass production, the vast majority of locks are repaired by swapping parts or like-for-like replacement or upgraded to modern mass-production items. Until more recently, safes and strongboxes were the exceptions to this, and large bank vaults are custom designed and built at great cost, the very limited scope for mass production of vaults means it is more difficult to realize economies of scale in their manufacture, and the risk of a copy being obtained and defeated is lowered when vaults are custom-made.[citation needed]
Although fitting of keys to replace lost keys to automobiles and homes and the changing of keys for homes and businesses to maintain security is still an important part of locksmithing, according to a 1976 US Government publication, locksmiths today are primarily involved in the installation of higher quality lock-sets and the design, implementation, and management of keying and key control systems. Most locksmiths also do electronic lock servicing, such as making smart keys for transponder-equipped vehicles and the implementation and application of access control systems protecting individuals and assets for many large institutions.[2]
In terms of physical security, a locksmith's work frequently involves making a determination of the level of risk to an individual or institution and then recommending and implementing appropriate combinations of equipment and policies to create security layers which exceed the reasonable gain to an intruder or attacker. The more different security layers are implemented, the more the requirement for additional skills and knowledge, and tools to defeat them all. But because each layer comes at an expense to the customer, the application of appropriate levels without exceeding reasonable costs to the customer is often very important and requires a skilled and knowledgeable locksmith to determine.
While a handyman can also install and replace locks, locksmiths are specialists whose involvement may be desirable for several reason. As mentioned above, their knowledge of different lock systems can help in appropriate lock selection and the establishment of best practices. Additionally, locksmiths in many places are required by law to undergo training and maintain certification.Condition report : The auction will be made in cash.
