Lock picking

 
 

Lock-picking is an ability possessed primarily by locksmiths and by persons involved in intelligence or detective work for which secrecy is a necessity. Requiring a high degree of reasoning power and mechanical dexterity, lock-picking even has its amateur enthusiasts who simply enjoy the challenge. The tools of the trade can involve an amazing array of devices, but most are variations on a simple pick mechanism that a skilled and patient practitioner can replicate even with a paper clip.

Basic technique. One of the simplest types of lock to pick is known as a pin-and-tumbler design. This lock uses a row of pins, divided into pairs, which rest in a row of shafts running perpendicular to the lock's main cylinder plug and its housing mechanism. Insertion of the right key forces the top and bottom pins apart at just the right distance so that all of the upper pins rest in the outer housing and all of the lower pins rest in the plug. At that point, no pins bind the plug to the housing, meaning that the cylinder can be turned freely, releasing the bolt that holds the locking mechanism in place.

To open such a lock without a key, one needs a long, thin piece of metal with a curved end (a pick), which can be inserted carefully inside the lock as one would a key. Moving with finesse, it is possible to adjust all the pins into place so that the cylinder can be turned as though the key had been used. Or one can apply a sloppier variation, known as raking, in which a pick is inserted and pulled out quickly while the cylinder is turned with a tension wrench such as a flathead screwdriver.

Tools. Experienced lock-pickers use a wide array of tools. They are likely to go to work using an entire tool kit with picks, "rakes" (picks for raking a lock), and tension wrenches, all of which are small enough that a basic lock-picking kit could fit into a pocket. To be equipped for a greater range of eventualities, a lock-picker may use a kit that includes other tools, such as a burglar alarm evasion kit, a key-impression kit (for making a key based on impressions that a lock makes on a key blank), a key-pattern device (for copying old-fashioned warded keys, made to fit into lever locks), files, and other items.

Even more sophisticated is an electric lock-opening device, which is used in tandem with a pick to move the pins into the proper position. Additionally, a lockpick gun can be used to open most pin-tumbler mechanisms. By squeezing the trigger, one strikes the pins with the pick, after which a tension wrench is applied to turn the lock cylinder.

There are other varieties of techniques and tools, just as there are variations in lock design, such as the wafer-tumbler lock, in which tumblers in the shape of wafers take the place of pins. Most aspects of lock-picking are simple in concept, but far from easy in application. Good locksmiths are almost always good lock-pickers, and the reverse is almost as true: a talented lock-picker, for instance, should be able to reconfigure a lock to fit a particular key, a skill that would obviously be of enormous advantage to an intelligence officer in a covert operation.

Lock picking is the skill of unlocking a lock by analyzing and manipulating the components of the lock device, without the original key. Although lock picking can be associated with criminal intent, it is an essential skill for a locksmith. Lock picking is the ideal way of opening a lock without the correct key, while not damaging the lock, allowing it to be rekeyed for later use, which is especially important with antique locks that would be impossible to replace if destructive entry methods are used.

Usually it is possible to bypass a lock without picking it. Most common locks can be quickly and easily opened using a drill, bolt cutters, padlock shim, a bump key or a hydraulic jack. The hasp, door, or fixture they are attached to can be cut, broken, or otherwise removed. Therefore a lock that offers high resistance to picking does not necessarily make unauthorized access more difficult, but will make surreptitious unauthorized access more difficult. Locks are often used in combination with alarms to provide layered security.

Some people enjoy picking locks recreationally, because they find it brings high satisfaction and is an enjoyable way to pass the time. This may also be referred to as Locksport.

Tool sets

The tools for lock picking are usually different for each type of lock and can sometimes be improvised from common items.

Lock pick kits can be purchased openly via the Internet. Many different selections are present. Nine-piece sets and a 32-piece set equipped with a Pick Gun for example differ in value and price greatly. However, many lock pickers state that for most locking devices, a basic set of five picks is enough; therefore it is unnecessary to carry around a wide variety of professional lock picks.

Tension wrench

A traditional pickset. From left to right: Torsion wrench, "twist-flex" torsion wrench, offset diamond pick, ball pick, half-diamond pick, short hook, medium hook, saw (or "L") rake, snake (or "C") rake.

Often called a torque wrench or a torsion wrench. A tension wrench is a tool used in picking locks. Typically shaped like a letter "L" (although the vertical part of the letter is elongated in comparison to the horizontal part), it is used to apply torsion to the inner cylinder of a lock, in order to hold any picked pins in place, while the other pins are shifted. The tension wrench is then used to turn the inner cylinder and open the lock.

Despite its popular name, the tool provides torsion, not tension. A tension wrench would be, by definition, a tool that stretches something. A torsion wrench would be a tool that twists.

Some tension wrenches (called "Feather Touch" wrenches, among other names) are coiled into a spring at the bend in the "L", which helps the user apply constant torque. Some users, however, maintain that such wrenches reduce torsion control and the feedback available to the user.

Half-diamond pick

Perhaps the most basic and common pick, this versatile pick is included in all kits and is mainly used for picking individual pins, but can also be used for raking and for wafer and disk locks.

Hook pick

It 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 generally used to lift the pins individually, rather than 'rake' them simultaneously.

Rake picks

These picks, such as the common snake rake, are designed to 'rake' pins by rapidly sliding the pick past all the pins, repeatedly, in order to bounce the pins until they reach the shear line. This method requires much less skill than picking pins individually, and generally works well only on cheaper locks.

Warded pick

A warded pick, also known as a skeleton key, is a device 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. This style of pick can also be used to 'rip' the lock. This is where the pick is placed at the back of the lock and then pulled out in one sharp fast 'ripping' action.

Pick guns

A traditional electric pick gun that runs off of C-cell batteries.
A traditional manual pick gun that is used by pulling the trigger.

Often seen in movies and in the tool box of locksmiths, manual and electronic pick guns are a popular method used today for quick and easy ways of opening doors. The higher-end electric pick guns are usually made of aircraft aluminum and hard steel. The pick is operated by simply pressing a button that vibrates while the normal tension wrench is being used. A manual pick gun (or Snap gun) is used in a similar way but usually has a "trigger" that creates an upward movement that must be repeated rapidly to open the lock.

Legal status

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. Illegal possession of lock picks is generally prosecuted as a felony under the category of possession of burglary tools or similar statutes. In many states, simple possession is completely legal as their statutes require proof of intent.

In California, locksmiths must be licensed by the state.[1] However possession by laymen may be legal there and in most states, as illegal possession must be coupled with felonious or malicious intent.[2] This is also the case in Utah,[3] Massachusetts, Maine, New Hampshire, Washington, DC,[4] and New York.

Canada

In Canada, possession of lock picking tools, with the exception of key duplication tools, is legal. However, Canadian Criminal Code prohibit the use or possession of Lock Picking tools with the intention to commit a crime. It is illegal to use lock picking tools to "trespass, commit an act of robbery or commit any other criminal offense". In short, 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 "intention to commit a crime". If you are found using Lock Picks to commit a crime, you may be charged with "Possession of tools with the intention of committing a crime" which carries a maximal penalty of 10 years in jail.[5]

European Union

Most countries of the European Union don't regulate the possession of lock picks. In fact some even encourage people to learn this skill since it can be useful in emergency situations.[citation needed] All responsibility concerning criminal or legal acts using the picks is taken by the user of the lock picks, when the owner of the lock picks may be involved in the jurisdiction or legal process as an accomplice or witness.

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 (organised by TOOOL), which was reported on in the newspapers.[6]

Poland

In Poland according to the delinquency Codeep Act article 129 § 1:
1) possessing, producing or obtaining a lockpick by a person whose profession and occupation doesn't require it;
2) delivering a lockpick to a person whose profession and occupation doesn't require it;
3) […]
is punishable with arrest, freedom limitation or fine. § 3 says that a lockpick is forfeited even if it wasn't a property of the principal.

United Kingdom

In the United Kingdom, a person who carries a lock pick set (even a home made one) can be charged with the offence of "going equipped to commit theft", unless they have a good reason for carrying them.[7] The penalty for this can be upward of 5 years' imprisonment. The arresting officer must have "reasonable cause".

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.[8]

Media

When lockpicking is shown in movies and television shows, the torsion wrench is almost always omitted. Picking a pin and tumbler lock without torsion is impossible unless there is a major defect in the lock.

In some modern dramas (such as Fox's 24) in which realistic depiction of events is favored, the pick-and-wrench technique is fully shown (albeit often executed in a second or two, which doesn't accurately reflect the luck involved with raking an unfamiliar lock).

Although there do exist raking tools in which a single element may be used to open a lock (such as automobile "tryout" keys), these are rarely used in media depictions, and almost as rarely used in real life. The broad width of these picks allows for the necessary application of torque, just as an external source of torque is not required when using a standard key.
