# Locksmithing

Locksmithing is the work of creating and bypassing locks. Locksmithing is a traditional trade and in many countries requires completion of an apprenticeship. The level of formal education legally required varies by country, ranging from no formal education to a training certificate awarded by an employer, or a full diploma from an engineering college, along with time spent as an apprentice.

## Terminology

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 both automatic and manual cutting tools to mold keys, with many of these tools being powered by batteries or mains electricity.

## Work

Locks have been constructed for over 2500 years, initially out of wood and later out of metal. 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.
Although replacing lost keys for automobiles and homes, as well as rekeying locks for security purposes, remains an important part of locksmithing, a 1976 US Government publication noted that modern locksmiths are primarily involved in installing high-quality lock-sets and managing keying and key control systems.

### Locksmith specialisations

Most locksmiths also provide electronic lock services, such as programming smart keys for transponder-equipped vehicles and implementing access control systems to protect individuals and assets for large institutions. Many also specialise in other areas such as:
* Auto Locksmithing
* Safes

## Regulation by country
### Australia

In Australia, prospective locksmiths are required to take a Technical and Further Education (TAFE) course in locksmithing, completion of which leads to issuance of a Level 3 Australian Qualifications Framework certificate, and complete an apprenticeship. They must also pass a criminal records check certifying that they are not currently wanted by the police. Apprenticeships can last one to four years. Course requirements are variable: there is a minimal requirements version that requires fewer total training units, and a fuller version that teaches more advanced skills, but takes more time to complete. Apprenticeship and course availability vary by state or territory.

### Ireland

In Ireland, licensing for locksmiths was introduced in 2016, with locksmiths having to obtain a Private Security Authority license. The Irish Locksmith Organisation has 50 members with ongoing training to ensure all members are up-to-date with knowledge and skills.

### United Kingdom

In the UK, there is no current government regulation for locksmithing, so effectively anyone can trade and operate as a locksmith with no skill or knowledge of the industry.

### United States

Nassau County and New York City in New York State, and Hillsborough County and Miami-Dade County in Florida have their own licensing laws.

## Employment

Locksmiths may be commercial (working out of a storefront), mobile (working out of a vehicle), institutional (employed by an institution) or investigatory (forensic locksmiths) or may specialize in one aspect of the skill, such as an automotive lock specialist, a master key system specialist or a safe technician. Many locksmiths also work as security consultants, but not all security consultants possess locksmithing skills. Locksmiths are frequently certified in specific skill areas or to a level of skill within the trade. This is separate from certificates of completion of training courses. In determining skill levels, certifications from manufacturers or locksmith associations are usually more valid criteria than certificates of completion. Some locksmiths decide to call themselves "Master Locksmiths" whether they are fully trained or not, and some training certificates appear quite authoritative.
The majority of locksmiths also work on any existing door hardware, not just locking mechanisms. This includes door closers, door hinges, electric strikes, frame repairs and other door hardware.

## Full disclosure

The issue of full disclosure was first raised in the context of locksmithing, in a 19th-century controversy regarding whether weaknesses in lock systems should be kept secret in the locksmithing community, or revealed to the public.
According to A. C. Hobbs:
   A commercial, and in some respects a social doubt has been started within the last year or two, whether or not it is right to discuss so openly the security or insecurity of locks. Many well-meaning persons suppose that the discussion respecting the means for baffling the supposed safety of locks offers a premium for dishonesty, by showing others how to be dishonest. This is a fallacy. Rogues are very keen in their profession, and know already much more than we can teach them respecting their several kinds of roguery.
   Rogues knew a good deal about lock-picking long before locksmiths discussed it among themselves, as they have lately done. If a lock, let it have been made in whatever country, or by whatever maker, is not so inviolable as it has hitherto been deemed to be, surely it is to the interest of honest persons to know this fact, because the dishonest are tolerably certain to apply the knowledge practically; and the spread of the knowledge is necessary to give fair play to those who might suffer by ignorance.
   It cannot be too earnestly urged that an acquaintance with real facts will, in the end, be better for all parties. Some time ago, when the reading public was alarmed at being told how London milk is adulterated, timid persons deprecated the exposure, on the plea that it would give instructions in the art of adulterating milk; a vain fear, milkmen knew all about it before, whether they practised it or not; and the exposure only taught purchasers the necessity of a little scrutiny and caution, leaving them to obey this necessity or not, as they pleased.

## Notable locksmiths

* William F. Banham, founder of Banham Security, invented the first automatic latch bolt lock in 1926 after a series of burglaries on his wife's dress shop.
