	~~Add~~ to ~~me!~~		Locks by definition secure or fasten something with the intention that access is possible only with the matching key. Despite this, criminal lock picking likely started with the first locks. Famed locksmith Alfred Charles Hobbs said in the mid-1800's:

			Rogues are very keen on their profession and know already much more than we can teach them to respect their several kinds of roguery. Rogues knew a good deal about lock-picking long before locksmiths discussed it among themselves...

			Professional and recreational lock picking also has a long history. King Louis XVI of France (1754–1793) was a keen designer, picker, and manipulator of locks, and physicist Richard Feynman picked locks for fun in the 1940's while employed on the Manhattan Project. The tradition of student roof and tunnel hacking at MIT included lock picking, and their guide to this was made widely available in 1991.

			Beginning in 1997 more organized recreational lock picking has now grown and developed a competitive aspect in "locksport", along with its own governing body, Locksport International.

			== Manipulation ==

			Decoding via manipulation focuses on invasive manipulation and analysis of the locking components to determine their correct positions. A wide range of tools and techniques exist to determine the number, size, shape, and position of components. In some cases, lockpicking or impressioning is a prerequisite to the decoding process.

			* In [[Pin_tumbler\|pin-tumbler]] locks, a tool may be used to determine bottom pin sizes once the lock has been picked. The tool measures the distance each pin can be raised until it gets to the top of the plug. Tools resemble pin-tumbler picks placed on a lever.

			* Tools to count or identify characterstics of components to identify their code.
			* Some lockpicking tools, namely [[Axial\|axial/tubular]] picks and the [[Sputnik]] tool, automatically decode or impression the lock while it is being picked.
			* [[Impressioning]], in a general sense, is a form of manipulation-based decoding that directly produces a working key.

			== Disassembly ==

			Disassembly of the lock will allow direct counts and measurements of internal components. These can be compared with manufacturing data to produce a working key. In some cases, disassembled components are imprinted with their sizes or codes, simplifying the process.

			== Measurement ==

			The key is measured to decode the values of the bitting cuts and the keyway profile. Various tools exist for specific locks, but a ruler or micrometer is equally effective in most cases.

			== Optical, Photographic, and Visual ==

			Visual observation of a key or lock allows for various forms of decoding.

			* Key bitting pattern. This process is known as "sight-reading" a key.
			* Key codes on the bow. Can also be used to identify the keyway of a lock.
			* Presence and position of secondary locking mechanisms such as [[Sidebar\|sidebars]].

			In [[Wafer\|wafer]] locks, a borescope or similar tool can be used to look at the position of each wafer as it rests in the lock.

			In [[Lever\|lever]] locks, a borescope or similar tool can be used to look at the shape of each lever, but requires that a secondary tool (a key) be used to move other levers out of the way.

			== Radiological ==

			Radiological imaging uses penetrating radiation (X, beta, and gamma rays) to see inside the lock or safe, revealing the proper positions of components. This is most often used against [[Combination\|combination]] locks to determine the position of each gate in the wheel pack. This is a surreptitious entry technique unless the use of such a device can be detected. In many cases, even if the ability to detect this form of entry is available it may be considerably expensive.

			The use of low-density wheel materials (such as Delrin) combats this attack. Group 1R safe locks are specifically designed to defeat various radiological attacks as well as provide manipulation protection.
