A standard set of pin-tumblerlockpicks and tension tools.

A lockpick (or pick, pick lock) is a tool used in lockpicking to manipulate components to their proper positions. The type of lock being picked and the preferences of the lockpicker will determine which type and style of lockpick used. In most cases, a tension tool is used with the pick to successfully pick the lock. Picks that are specifically designed for rake picking techniques as known as rakes.

The possession of lockpicks is considered illegal in some parts of the world. Lockpicks are categorized as "burglary tools" in many places, but most laws do not consider them such until they are used with the intent to commit a crime.

Types of Picks

The type and design of lockpicking tools varies greatly. Different lock designs require different types of picks and tension tools to manipulate the internal components.

Pin-tumbler picks

Pin-tumbler picks are typically flat, thin pieces of metal. The tip of the pick comes in various shapes designed to facilitate movement and feedback in the lock. Common handle materials are metal, heat shrink tubing, plastic, rubber, and wood.

  • Ball / Round
  • DeForrest pick
  • Diamond
  • Long hook
  • Half ball
  • Reach pick
  • Short hook
  • Snowman / Figure 8
  • Rakes (commonly snake, C rake, S rake, M rake, L rake, City rake)
  • Bogota rake
Dimple picks

Dimple picks use small, "flag" style picks that are rotated rather than raised. These are smaller than pin-tumbler picks and come in a variety of designs. Dimple rakes are also common. Traditional pin-tumbler picks can also be used to pick dimple locks.

Disc-detainer picks

Disc-detainer picks typically use a 2-in-1 Hobbs style pick which provides independent torsion and manipulation controls. Some, such as the Ford Tibbe 6 disc lock have dedicated picks which allow manipulation and tension of each disc via a system of telescoped tubes.

Lever picks

Lever picks came first in the form of bent pieces of wire as well as the traditional jigglers and skeleton keys, the latter of which were a hold-over from picks for warded lever locks. For the more advanced multi-lever locks, 2-in-1 Hobbs style picks were invented and refined, and are still common for non-curtained locks. Other methods include try-out keys, pin & cam systems and various means to read the lever number via the keyhole or, occasionally, elsewhere, via systems such as plasticine reader keys, rotational measurement devices and, especially for detainer lever locks, a steerable fibrescope which can optically decode the gate positions.

Tubular picks

The simplest pick for a tubular lock is a tensioner and a straight piece of wire. Picking proceeds as with other lock types. More commonly, a dedicated pick is used, which has a wire for each pin arranged to match the 7, 8 etc. pins as well as a method for tensioning the lock. These are normally used to self-impression the lock, meaning that the tool will use the binding order of the lock to recreate the correct key without prior knowledge, and can be startlingly effective against locks that have no countermeasures to them. Against those with countermeasures, a dedicated pick such as the Peterson Pro1 is normally required which will allow each pick wire to be adjusted individually by hand.

Wafer picks

Wafer locks share picking tools with pin-tumbler locks but also have their own variety of picks which include wavy, smooth designs. Wafer picks are often marketed as "jigglers" due to the heavy emphasis on raking techniques to open these locks.

Warded picks

Picks for warded locks can consist of bent wires, but more commonly they consist of simplified keys, known as skeleton keys. A set of keys can be simplified to create one or two keys that will open the entire range of that type of warded lock, be it a warded single lever mortice lock or a warded padlock.

A lockpick is a type of key with a few unique properties :

  • Lockpicks can unlock any generic locked chest
  • Lockpicks are not always consumed upon use but have a chance of being retained.
    • Retention is considered as a game of chance for the purpose of the Lucky and Unlucky titles. Successfully retaining will count as winning 250 tickets, breaking will count as losing 2.5 games of chance for every 1% of the retention rate of the chest.

These properties make lockpicks strictly superior to keys in functionality, however they are usually more expensive and more difficult to acquire.


Eye of the North

Retention Rate[edit]

Each chest has a base retention rate that depends on the price of the equivalent key associated with this type of chest. In addition, a bonus inherent rate is applied, that depends on the character's level and the account's rank in the Treasure Hunter and Lucky title tracks. This bonus rate is equal to :

Bonus Rate = ( 0.5 * Level + 3 * Treasure Hunter rank + 2 * Lucky rank ) / 100

The bonuses for all potential combinations of account-wide title ranks for a level 20 character are given in the right table below:

For instance, without any bonuses from titles, the retention rate for Jade Sea chests at level 20 is 40% (30% from the chest itself, as the equivalent key costs 600Gold gold, plus 10% from the character being at level 20). With a rank 2 in the treasure hunter title (+6%) and Lucky title (+4%), the retention rate becomes 50%.

One lockpick is expected to open an average of 1/(1-RR) chests, with RR the total retention rate. If opening locked chest in hard mode for example, with rank 2 in both Lucky and Treasure Hunter (RR=20%), one lockpick is expected to open 1,25 chests, so four lockpicks are expected to open five locked chests ().

Lockpicks vs keys[edit]

For characters without any ranks in Lucky or Treasure Hunter, it is almost always more cost-effective to use keys instead of lockpicks to open chests.

The higher the title track ranks, however, the higher the lockpick retention rate and therefore the higher the number of chests it can open, to the point where it can become more cost-effective to use a lockpick instead of a regular key. The first table below shows the breakpoint for lockpicks bought from a merchant at 1Platinum 500Gold while the second table uses the common player trade price of 1Platinum 250Gold. If the player's bonus rate is equal to the given value, using keys or lockpicks will cost you as much. If it is higher, using lockpicks will be cheaper.


  • Since Faction merchants are only available in alliance-controlled outposts, it is not uncommon for some players to resell the discounted lockpicks to other players for a small margin.

Lock picking

Manipulating the components of a lock to unlock it without the original key

"Lockpick" redirects here. For other uses, see Lockpick (disambiguation).

Lock picking is the practice of unlocking a lock by 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 the legitimate profession of locksmithing, and is also pursued by law-abiding citizens as a useful skill to learn, or simply as a hobby (locksport).

In some countries, such as Japan, lock-picking tools are illegal for most people to possess, but in many others, they are available and legal to own as long as there is no intent to use them for criminal purposes.


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...[1]

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,[2] 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,[3] and their guide to this was made widely available in 1991.[4]

Beginning in 1997[5][6] more organized recreational lockpicking has now grown and developed a competitive aspect in "locksport", along with its own governing body, Locksport International.[7][8]


Skeleton keys[edit]

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, if you have a chest of drawers with a warded lock you can make a skeleton key for that type of warded lock 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.

Lever tumbler lock picking[edit]

Curtain pick[edit]

Lever tumbler locks can be opened by a type of lockpick called a curtain pick.[9]

Pin tumbler lock picking[edit]

Tension wrench[edit]

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[edit]

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 12.2 millimeters (0.098 to 0.480 inches) 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[edit]

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[edit]

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 picks[edit]

Two types of rake pick, the double and triple peak, sometimes known as Bogota rakes.

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[edit]

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 keys[edit]

The simplest way to open the majority of pin locks is to insert a key (or variety of keys) that have 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.[10] Some modern high security locks include bumping protection, such as Master Lock's "BumpStop"[11] and Ilco's "Bump Halt"[12] technology.

Wafer tumbler lock picking[edit]

Jigglers or try-out keys[edit]

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 guns[edit]

Main article: Snap gun

The manual pick gun (or snap gun) was invented by Ely Epstein.[13] 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 those pins only 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 now also common, whereby simply pressing a button the pins are vibrated while the normal torsion wrench is being used.

Tubular lock pick[edit]

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 pick 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[edit]

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". 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.[14]

Legal status[edit]


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."[15][16]


In every province of Canada, a licence is required to carry out locksmithing professionally. It is legal for hobbyists who are not locksmiths to pick locks that they own.[citation needed]

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. 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 offence punishable on summary conviction.[17]

Some provinces require a license to carry lock picks.[18] 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.[19] 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.[20] 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.


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.[21] Lock picking has also become a popular part of geocaching in Germany.[22] There are also lock picking workshops at geocaching events.[23]

European Union[edit]

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.


Unusually for a country in the EU, ownership of lock picks in Hungary is completely prohibited, even for professional locksmiths. Lock picks are classified as military equipment, and may only be legally obtained or used by Hungary's armed forces.[24]


Japan's law prohibits possession of any lock picking tools and imposes a penalty of one-year imprisonment or a 500,000 yen fine.[25]


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.[26][27]

New Zealand[edit]

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.[28]


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.[29]

United Kingdom[edit]

In England and Wales, a person who, not within their abode, has anything to be used to commit burglary or theft can potentially be prosecuted. The penalty for this can be up to 3 years imprisonment.[30]

United States[edit]

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.[31] This is the case in Arizona,[32] California,[31] Utah,[33] Maine,[citation needed] Massachusetts,[34] New Hampshire,[35] Washington D.C., Washington State,[36] and New York.[37] 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.[31][38][39]

Learn Lock Picking: EVERYTHING you Need to Know!

Lockpicking is the art of opening a lock through the analysis and manipulation of its components without using a key intended to open the lock. The process is generally non-destructive and covert, and is contrasted with various forms of destructive entry. When dealing with the opening of safes or vaults, it is referred to as safecracking. A bypass is technically different than picking the lock, though there are many similarities between the two techniques.

Lockpicking is made possible by small irregularities during the manufacturing of locks. Small variations in the size, shape, and alignment of components allows for picking tools to be used to pick the lock. Depending on the type of lock, different methods of picking may be available.

The practice of recreational or competitive lockpicking is known as locksport.


Theoretically, lockpicking has existed as long as locks themselves. Early locks, from the Romans until Barron's invention of the double-acting tumbler in 1778 relied solely on wards. Warded locks were usually opened by a skeleton key, cut away to pass any and all wards which might be in the lock. 'Skeleton key' could mean any skeleton-like instrument achieving this purpose, such as a piece of bent wire. (It does not include bit keys for lever locks.) Robert Barron patented [BP1200] the principle of all modern mechanical security locks — the double-acting movable detainer. Thereafter, tentative picking was developed, using 2 instruments. One applies a binding pressure, the other moves whatever movable detainer is obstructing the movement of the bolt (or plug, in a cylinder lock).

Picking Methods

There are various methods used to successfully pick a lock. There is no "right" way to pick; every lockpicker has their own preference. The most common types of picking are listed:

Single Component Picking
A pick designed to manipulate individual components is used. Single pin picking focuses on the irregularities of each individual component to determine the order of binding and proper position of each component. Commonly referred to as single "pin" picking, but applicable to non-pin locks, too. Though many pick types are suitable, the classic hook shaped pick is most appropriate.
A pick designed to manipulate many (or all) components is used. Raking focuses on rapidly varying the position of components in the lock to simulate a wide variety of key depths. Raking is especially effective if the proper position of components is in a predictable pattern, such as a staircase. Picks specifically designed for raking are known as rakes.
Pick Guns
A pick gun is designed to hit the bottom of all pins and transfer energy to the pin stacks to allow for rapid opening of the lock mechanism. Vibration picks fall into this same category.
Bump Keys
A key with depth cuts to the lowest positions. Key bumping is a fundamental problem in most pin tumbler locks that allows for energy transfer between the bump key and the pin stacks to allow for rapid opening of the lock mechanism. This is similar in function to the use of a pick gun.
Tryout Keys
A set of keys modified to different depth positions. Tryout keys take advantage of poor tolerances in locking components. While most locks represent themselves as having a large amount of theoretical key differs, some have very few due to poor tolerances.
Comb Picks
A pin-tumbler pick designed to move all pin stacks out of their blocking position by pushing them into the cylinder chambers, allowing the plug to rotate freely.
The process of duplicating or otherwise simulating the action of a proper key for the target lock. Impression can take many forms, some of which are not strictly classified as lockpicking.
The process of decoding the position of internal components either through manipulation of components, disassembly of the lock, or analysis of the key. Decoding can take many forms, most of which are not strictly classified as lockpicking.

Tools Used

See Lockpicks.

The specific tools used to open a lock depend on the design of the lock and the preferences of the lockpicker.

Traditional picking of most locks involves both picks and tension tools. The pick is used to manipulate internal components to their unlocked position and the tension tool is used to hold the components in place and retract the locking bolt once the lock is picked. When all components are in the unlocked position the lock is free to open and considered picked. This applies to pin-tumbler, tubular/axial, dimple, and lever locks.

Most forms of lock picking are covert rather than surreptitious as minor scarring can occur to the face and pins of the lock that can aid in forensic analysis.

Warded locks are distinct because they do not require a tension tool to be picked; only the picking tool is used.

Combination locks generally do not require tools unless they are a hybrid locking design. Most combination locks are opened with decoding or bypass rather than picking.

Handcuff locks that use a warded design can be picked with simple tools, including paper clips, bobby pins, and traditional pin-tumbler or warded lockpicks. Most handcuffs can be bypassed via shimming or manipulation of the ratchet arm instead of attacking the lock mechanism directly.

Lockpicking in the Media

Lockpicking has been portrayed in many television shows and films. Often techniques and tools are incorrect, with the most common mistake being the lack of a tension tool. In most cases the lock is picked almost instantly, which misrepresents the difficulty and skill involved in picking the majority of locks.

It unlocks doors, chests, and blocks without consuming the peasant's keys. Each time it is used its probability to break goes up by 2%. Its chance, in percentage, can be found on the relic's icon. The lockpick will still spare the use of a key when it breaks.

It can be combined with Lucky Charm.pngLucky Charm to obtain the Lucky Lockpick.pngLucky Lockpick.

On average, it is worth about 9.5 Keys (See derivation below).

The chance of the lockpick breaking can be reset to 0 by placing it on the Relic Altar and removing.




  • Will not replace key-based payment when buying something from Black Rabbit.

Statistical Analysis of the Lockpick[]

A statistical analysis is useful for determining how many keys finding the lock pick will save you. The following sections will walk through the derivation and steps taken to determine the statistics behind the item.

Derivation of the Probability Density Function[]

Let X be the number of keys the lockpick saves the peasant. Since the lockpick saves the peasant a key even when it breaks, the minimum number of keys saved is 2 and the maximum number of keys saves is 51.

Therefore, X = {2, 3, …, 50, 51}.

In order to derive the average number of keys the lockpick will save the peasant, a probability density function (PDF) must be found. To derive this expression, let f(X) be the probability of the lockpick not breaking until the point of breaking for X number of saved keys. Similarly, let g(X) be the probability of the lockpick breaking for X number of saved keys. Constructed below is a table of f(X) and g(X) for early values of X.


From the table, it is easy to see a linear relationship between the probabilities of breaking (or not breaking), and the amount of keys the lockpick has saved the peasant. These relationships can be expressed using:

{\displaystyle f(X)=1.04-0.02X}

{\displaystyle g(X)=0.02(X-1)}

Now that the probabilities of breaking and not breaking for the number of saved keys in known, it is possible to derive the PDF for the number of keys saved. The probability for saving X amount of keys is equal to the probability of the lockpick surviving X-1 times and breaking on the Xth try.


{\displaystyle P_{X}(X)=g(X)\prod _{i=2}^{X}f(i)}

{\displaystyle =0.02(X-1)\prod _{i=2}^{X}1.04-0.02i}

A quick check of the summation of probability across the entire sample space shows that the probability of all events is 1:

{\displaystyle \sum _{X=2}^{51}0.02(X-1)\prod _{i=2}^{X}1.04-0.02i=1}

Mean and Variance[]

Now that the PDF of the amount of keys saved is known, all that is needed now is to apply the definitions of mean and variance.

Mean is calculated by:

{\displaystyle E[X]=\mu =\sum _{}^{k}kP_{X}(k)}

Variance is calculated by:

{\displaystyle Var(X)=\sigma ^{2}=\sum _{}^{k}(k-\mu )^{2}P_{X}(k)}

Applying these definitions results in:

{\displaystyle E[X]=\sum _{k=2}^{51}0.02k(k-1)\prod _{i=2}^{k}1.04-0.02i=9.54}

{\displaystyle Var(X)=\sum _{k=2}^{51}0.02(k-\mu )^{2}(k-1)\prod _{i=2}^{k}1.04-0.02i=18.47}

Thus, the lockpick, on average, will save the peasant 9.5 keys.

How to Pick a Lock (Basics) 🔓


Lockpicking is a way to open locked doors. It is a less noisy way to open doors compared to a crowbar, which can be used if you have high enough strength to noisily break open a door. Lockpicks require mechanics, a lockpicking tool, and use the dexterity attribute.

  • Lockpicking creates no noise, but it can set off alarms, but the likelihood is reduced.
  • Failing to pick a gunsafe can jam the lock. Forcing you to use brute force to open the safe. Which can damage the contents.
  • There are doors, chainlink fences, and gunsafes you can unlock with mechanical tools.
  • To unlock the normal safes you can find in places like banks or doctor's offices, you cannot use lockpicking tools. You need to not be deaf, and use a Stethoscope to crack the safe. An Enhanced Hearing CBM may be used in place of a Stethoscope. Or, you can try your luck by messing with the lock by examining the safe.(one in 27000 chance).
    • Deaf character cannot crack mechanical safes.
  • Some gunsafes are electronical, and can only be opened with electronic hack tools, and the computer skill.

Technical Stuff

First, we should calculate the "weighted skill average" by using the following formula :

weighted skill average = (3*Devices skill + Mechanics skill) / 4

Then we calculate the "weighted stat average" through using:

weighted stat average = (6* dexterity + 2* perception + intelligence) / 9

After that we get the "tool effect", if the tool effect gives a bonus if it's higher than three, or a penalty if below three:

tool effect = ( lockpick quality- 3 ) - ( tool damage / 2000.0 )

Then we take proficiency into account:

proficiency effect = -3 without lockpicking proficiency, or 0 with basic lockpicking proficiency, or 3 with locksmith proficiency.

With the values above ready, we calculate the "mean roll" by doing:

mean roll = weighted skill average + ( weighted stat average / 4 ) + proficiency effect + tool effect

The "pick roll" is generated by "mean roll" with a standard deviation of 2, basic idea being: about 2/3 of rolls will come within 2 points of the "mean_roll".

pick_roll = std::round( normal_roll( mean_roll, 2 ) );

As of 0.F-2 stable, the game picks a random number within 0-12 (generated by 3d5-3, which means higher chance to have a result near 6 and lower chance near 0 or 12) to be chosen as the "lock roll". This is planned to be replaced by lock difficulty of each lock in the future.

Now, if your "pick roll" is higher than or equal to "lock roll", you will successfully pick the lock.

If "lock roll" is higher than "pick roll", you will fail.

If "lock roll" is higher than ( 1.5 * "pick roll" ), you will fail AND damage your lockpicking tool.

If you are lockpicking a gun safe and "lock roll" is higher than (3 * "pick roll"), you will fail AND your clumsy attempt will jam the lock.

List of lockpicking tools

In order of pick quality. Higher is better.
