Lock picking

History

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-1800s:

Rogues are very keen on 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...

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 1940s while employed on the Manhattan Project. The tradition of student roof and tunnel hacking at MIT included lockpicking, and their guide to this was made widely available in 1991.

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

Tools

Skeleton key

Main article: Skeleton Key

The warded pick, also known as a skeleton key, is used for opening warded locks. It is generally made to conform to a generalized key shape relatively simpler than the actual key used to open the lock; this simpler shape allows for internal manipulations.

The keys for warded locks only require the back end manipulating which is the end which opens the lock. The other parts are there to distinguish between different varieties of their locks. For example, for a chest of drawers with a warded lock, a skeleton key for that type of warded lock can be made by filing away all but the last one or two teeth or bittings on both sides of the blade. Additionally, a series of grooves on either side of the key's blade limit the type of lock the key can slide into. As the key slides into the lock through the keyway, the wards align with the grooves in the key's profile to allow or deny entry into the lock cylinder.

Pin tumbler lock picking

Comb pick

Comb picks push all the key and driver pins above the shear line allowing you to open the lock. Comb picks require extreme precision in order to use properly without failing.

Tension wrench

The tension wrench or torsion wrench, is generally used when picking a pin tumbler or wafer lock. It is used to apply torque to the plug of a lock to hold any picked pins in place. Once all pins are picked, the tension wrench is then used to turn the plug and open the lock. There are two basic types of tension: "bottom of the keyway" and "top of the keyway". The bottom of the keyway wrenches is typically shaped like a letter "L", although the vertical part of the letter is elongated in comparison to the horizontal part. Other tension tools, especially those for use with cars, resemble a pair of tweezers and allow the user to apply torque to both the top and the bottom of the lock. These are commonly used with double-sided wafer locks.

Half-diamond pick

This versatile pick is included in nearly all kits and is mainly used for picking individual pins, but can also be used for raking and wafer and disk locks. The triangular-shaped half-diamond is usually 2.5 to long. The angles that form the base of the half-diamond can be either steep or shallow, depending on the need for picking without affecting neighboring pins, or raking as appropriate. A normal set comprises around three half-diamond picks and a full-diamond pick.

Hook pick

Hook pick The hook pick is similar to the half-diamond pick but has a hook-shaped tip rather than a half-diamond shape. The hook pick is sometimes referred to as a "feeler" or "finger" and is not used for raking. This is the most basic lockpicking tool and is all that a professional will usually need if the lock is to be picked in the traditional sense rather than opened by raking or using a pick gun. A variety of differently sized and shaped hooks are available in a normal set.

Ball pick

The ball pick is similar to the half-diamond pick, except the end of the pick has a half or full circle shape. This pick is commonly used to open wafer locks.

Rake pick

These picks, such as the common snake rake, are designed to rake pins by rapidly sliding the pick past all the pins, repeatedly, to bounce the pins until they reach the shear line. This method requires much less skill than picking pins individually and generally works well on cheaper locks. Advanced rakes are available which are shaped to mimic various pin height key positions and are considerably easier to use than traditional rakes. Such rakes are typically machined from a template of common key configurations since not all permutations of pin heights for adjacent pins are possible given the process by which keys are manufactured.

Decoder pick

The decoder pick is a key which has been adapted such that the height of its notches can be changed, either by screwing them into the blade base or by adjusting them from the handle while the key is in the lock. This will allow not only access to the lock but also a template for cutting a replacement key.

Bump key

The simplest way to open the majority of pin locks is to insert a key (or variety of keys) that has been cut so that each peak of the key is equal and has been cut down to the lowest groove of the key. This key is then struck sharply with a hammer whilst applying torque. The force of the blow is carried down the length of the key and (operating as does a Newton's cradle) will move only the driver pins, leaving the key pins in place. If done correctly, this briefly creates a gap around the shear line, allowing the plug to rotate freely. Some modern high-security locks include bumping protection, such as Master Lock's "BumpStop" and ILCO's "Bump Halt" technology.

Wafer tumbler lock picking

Jigglers or try-out key

The majority of wafer tumbler locks can be opened with a set of jigglers or try-out keys. They can also be opened with pin-tumbler picks.

Pick gun

Main article: Snap gun

The manual pick gun (or snap gun) was invented by Ely Epstein. It usually has a trigger that creates a movement which (like bump keys) transfers sudden energy to the key pins, which communicate this to the driver pins, causing only those pins to jump, allowing the cylinder to turn freely for a brief moment, until the pin springs return the pins to their locking position. Electric versions are also common, whereby simply pressing a button vibrates the pins while a normal torsion wrench is being used.

Tubular lock pick

A tubular lock pick is a specialized lockpicking tool used for opening a tubular pin tumbler lock. Tubular lock picks are all very similar in design and come in sizes to fit all major tubular locks, including 6, 7, 8, and 10-pin locks. The tool is simply inserted into the lock and turned clockwise with medium torque. As the tool is pushed into the lock, each of the pins is slowly forced down until they stop, thus binding the driver pins behind the shear line of the lock. When the final pin is pushed down, the shear plane is clear and the lock opens. This can usually be accomplished in a matter of seconds.

Most tubular lock picks come with a "decoder" which lets the locksmith know at what depths the pins broke the shear plane. By using the decoding key after the lock has been picked, the locksmith can cut a tubular key to the correct pin depths and thus avoid having to replace the lock.

Anti-picking methods

The history of lock development, particularly modern locks, is largely one of an arms race between lock pickers and lock inventors.

Today's anti-picking methods in standard pin tumbler locks include the use of sidewards which obstruct the keyway and "security pins" or "carnival pins". These are shaped like a spool, mushroom, or barrel, with the effect that they feel as though they have set when in fact they have not. Security pins can also have the effect of resetting other pins when adjusted.

Legal status

Australia

In Australia, possession of lock picking equipment is legal. However, it may count toward evidence of intent to commit a crime if otherwise incriminating circumstances warrant reasonable suspicion by police. For example, Queensland state law states:

"A person possessing lock picks, an electronic car door lock scanner, or a jemmy in other than easily explainable circumstances, e.g., a locksmith, carpenter, or a person undertaking home renovations, may warrant the suspicion of police that the person may intend to used [sic] the equipment for a burglary or vehicle theft. Obviously, the suspicion held by police must be reasonable and therefore will be dependent on the circumstances under which the person is found with the items."

Canada

In B.C. and Ontario Canada, a license is required to carry out locksmithing professionally. It is legal for hobbyists who are not locksmiths to pick locks that they own.

Under Section 351 of the Canadian Criminal Code, lock pick tools fit in the same category as crowbars or hammers, meaning they are legal to possess and use unless they are used to commit a crime or if it is shown there was the intention to commit a crime.

The relevant section states: "Every person who, without lawful excuse, has in their possession any instrument suitable for breaking into any place, motor vehicle, vault or safe knowing that the instrument has been used or is intended to be used for that purpose,

(a) is guilty of an indictable offense and liable to imprisonment for a term not exceeding ten years; or

(b) is guilty of an offense punishable on summary conviction."

Some provinces require a license to carry lock picks. Unlike most laws in Canada, the onus is on the defendant to prove that they have a legal purpose to use the lock picks. Similar to some drug trafficking offenses, this may be automatically applied if possession is discovered, though corroborating evidence is needed to support these charges. Hobbyist use and indications thereof should constitute reasonable doubt, though the defendant must prove legal purposes, the crown must still indicate the charges are reasonable given the circumstances. For example, the discovery of lock picks in a dwelling house in absence of other indications of burglary are not grounds for this charge. It is not uncommon for hackathon events in Canada to have lock picking challenges, and this would constitute a reasonable and legal reason for possession.

Germany

There is no law or regulation on lock picking, so it is legal as long as one has permission from the owner of the lock to pick the lock in question. Lock picking tools can be freely bought and sold. There are several clubs where lock picking is practiced as a sport. Lock picking has also become a popular part of geocaching in Germany. There are also lock picking workshops at geocaching events.

European Union

Most countries of the European Union don't regulate the possession of lockpicks. All responsibility concerning criminal or legal acts using the picks is taken by the owner of the lockpicks.

Hungary

Unusually for a country in the EU, ownership of lock picks in Hungary on public property is prohibited.

Japan

Japan's law prohibits possession of any lock picking tools and imposes a penalty of one-year imprisonment or a 500,000 yen fine.{{cite act

Netherlands

In the Netherlands, owning lock picks is legal, but using them on someone else's locks without permission is not. There is a lock picking championship, the Dutch Open (organized by TOOOL), which started in 2002 and features competitors from around the world. The competition is held during LockCon, an annual conference about locks."Lock pickers hebben slot in paar seconden open", the Leeuwarder Courant, December 2, 2002

New Zealand

In New Zealand, lock picking tools are not illegal, but possession with the intent to use them for burglary carries a potential penalty of three years in prison.

Poland

In Poland, according to Article 129/1 of the Misdemeanor Code: both (1) possessing, producing or obtaining a lock pick by a person whose profession and occupation does not require it; and (2) delivering a lock pick to a person whose profession and occupation does not require it is punishable with arrest, freedom limitation or fine - and (3) a lock pick is forfeited even if it was not the property of the principal.

United Kingdom

In England and Wales, a person who, not within their abode, has any article to be used in the course of or in connection with any burglary or theft can potentially be prosecuted. A successful prosecution would need to prove intention to use the tools for that purpose at the time of possession. As an either way offence, the maximum penalty for this is 3 years imprisonment if tried in the Crown Court, and 12 months if tried in the Magistrates' Court.

United States

In the United States, laws concerning possession of lock picks vary from state to state. Generally, possession and use of lock picks is considered equivalent to the possession of a crowbar or any other tool that may or may not be used in a burglary. Possession of lock picks with an intent for their unlawful use is generally prosecuted as a misdemeanor under the category of possession of burglary tools or similar statutes. In many states, simple possession of lock picks is completely legal, as the statutes only prohibit the possession of lock picks or the activity of lock picking when there is a malicious intent. This is the case in Arizona, California, Maine, Massachusetts, New Hampshire, Washington D.C., Washington State, and New York. Some states, such as California and New York, impose restrictions on businesses, such as prohibiting the operation of a locksmithing business without a license and imposing requirements to keep records about sales of lock picking devices.
