Locksmithing is the work 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, 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 mould 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.
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] Many also specialise in other areas such as:
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. [3]
In Ireland, licensing for locksmiths was introduced in 2016, [4] 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.
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. [5]
Fifteen states in the United States require licensure for locksmiths. Nassau County and New York City in New York State, and Hillsborough County and Miami-Dade County in Florida have their own licensing laws.

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. [2] Many are also security consultants, but not every security consultant has the skills and knowledge of a locksmith. 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.
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.
Lock picking is the practice of unlocking a lock by manipulating the components of the lock device without the original key.
A warded lock is a type of lock that uses a set of obstructions, or wards, to prevent the lock from opening unless the correct key is inserted. The correct key has notches or slots corresponding to the obstructions in the lock, allowing it to rotate freely inside the lock.
Linus Yale Jr. was an American businessman, inventor, mechanical engineer, and metalsmith. He was a co-founder with millionaire Henry R. Towne of the Yale Lock Company, which became the premier manufacturer of locks in the United States. He was the country's leading expert on bank locks and its most important maker. By the early 20th century, about three-quarter of all banks in America used his bank locks. He is best remembered for his inventions of locks, especially the cylinder lock, and his basic lock design is still widely distributed today, and constitutes a majority of personal locks and safes.
The pin tumbler lock, also known as the Yale lock after the inventor of the modern version, is a lock mechanism that uses pins of varying lengths to prevent the lock from opening without the correct key.
A combination lock is a type of locking device in which a sequence of symbols, usually numbers, is used to open the lock. The sequence may be entered using a single rotating dial which interacts with several discs or cams, by using a set of several rotating discs with inscribed symbols which directly interact with the locking mechanism, or through an electronic or mechanical keypad. Types range from inexpensive three-digit luggage locks to high-security safes. Unlike ordinary padlocks, combination locks do not use keys.
A lock is a mechanical or electronic fastening device that is released by a physical object, by supplying secret information, by a combination thereof, or it may only be able to be opened from one side, such as a door chain.
A lever tumbler lock is a type of lock that uses a set of levers to prevent the bolt from moving in the lock. In the simplest form of these, lifting the tumbler above a certain height will allow the bolt to slide past.
A Chubb detector lock is a lever tumbler lock with an integral security feature, a re-locking device, which frustrates unauthorised access attempts and indicates to the lock's owner that it has been interfered with. When someone tries to pick the lock or to open it using the wrong key, the lock is designed to jam in a locked state until either a special regulator key or the original key is inserted and turned in a different direction. This alerts the owner to the fact that the lock has been tampered with.
A mortise lock is a lock that requires a pocket—the mortise—to be cut into the edge of the door or piece of furniture into which the lock is to be fitted. In most parts of the world, mortise locks are found on older buildings constructed before the advent of bored cylindrical locks, but they have recently become more common in commercial and upmarket residential construction in the United States. The design is widely used in domestic properties of all vintages in Europe.
Joseph Bramah was an English inventor and locksmith. He is best known for having improved the flush toilet and inventing the hydraulic press. Along with William Armstrong, 1st Baron Armstrong, he can be considered one of the two fathers of hydraulic engineering.
Padlocks are portable locks usually with a shackle that may be passed through an opening to prevent use, theft, vandalism or harm.
Alfred Charles Hobbs was an American locksmith and inventor. He was born in Boston, Massachusetts, in 1812; his father was a carpenter. He married Charlotte F. Nye (1815-?) of Sandwich, Massachusetts, in 1835 and had four children: Charlotte Hobbs, Alfred J. Hobbs (1843-?), Mary H. Hobbs, and Arthur Hobbs. Both of his parents were born in England.
Rekeying a lock is replacing the old lock pins with new lock pins.
Lock bumping is a lock picking technique for opening a pin tumbler lock using a specially crafted bump key, rapping key or 999 key. A bump key must correspond to the target lock in order to function correctly.
A wafer tumbler lock is a type of lock that uses a set of flat wafers to prevent the lock from opening unless the correct key is inserted. This type of lock is similar to the pin tumbler lock and works on a similar principle. However, unlike the pin tumbler lock, where each pin consists of two or more pieces, each wafer in the lock is a single piece. The wafer tumbler lock is often incorrectly referred to as a disc tumbler lock, which uses an entirely different mechanism.
The term protector lock has referred to two unrelated lock designs, one invented in the 1850s by Alfred Hobbs, the other in 1874 by Theodor Kromer.
A magnetic keyed lock or magnetic-coded lock is a locking mechanism whereby the key utilizes magnets as part of the locking and unlocking mechanism. Magnetic-coded locks encompass knob locks, cylinder locks, lever locks, and deadbolt locks as well as applications in other security devices.
Banham Group is a family owned security company. Established in 1926, Banham Group is now the largest supplier of burglary and fire prevention systems in London.
The Bramah lock was created by Joseph Bramah in 1784. The lock employed the first known high-security design.
