Video instruction on hacking the lock with a hair clip

The concept that this method is based on the tumbler, so that as you pick one pin, it will stay in the unlocked position. All you have to do is just go down the line of pins and push up on the one that is currently stuck. You will be able to tell by how much force it takes to lift a pin, which one to push up on next. Once a pin is picked, you will hear a click of a noise signaling for you to move to another pin. Be sure to keep the constant rotational pressure on the lock, because if you do not, then the pins will spring back down and you will have to start over again.

Cylinder locks

Guide for unlocking locks

To date, the most common way to break a lock with a cylinder mechanism is to break the cylinder mechanism in half. In the photo you see already the result of the breakdown of the cylinder mechanism.

And the technique itself is as follows. The thief searches for apartments with wooden doors and locks with a profile cylinder, as a rule, these are accessible to all KALE, APEX, etc. How much they cost, so much and take care of the apartment. Then the decorative cover covering the hole in the door is loosened, where the cylinder mechanism of the lock was inserted. If to the right and to the left of the cylinder there is a space of 5 mm, this is enough to grip the protruding part of the cylinder with nippers or pliers and to swing it hard to the right and to the left. Everything, the cylinder broke in the central part and it must be pulled out of the lock. Now you can unlock the lock with any hook. In terms of time it takes 2-3 minutes. If the door was done in good faith and the cylinder mechanism snugly enters the door, then the hole is quickly widened with a screwdriver or chisel, this does not work. A little more difficult if the door is metal, but it will not hold the thieves any longer.

Maybe someone will say, but where is the way out? He is. And know that dozens of people a day suffer from theft, only because of the dishonesty of the manufacturers of locks and profile cylinders. The output is very simple and well known. The photographs show and without commentary how to strengthen the cylinder mechanism of the lock. Simple, cheap and reliable. I do not think that the metal plate, bent by the letter "P" with six holes, will greatly increase the price of the part. I just think that producers do not respect you and keep you for fools, but you all buy such locks, encouraging them to continue production of deliberately waste products.

No matter how much they write, not to put Turkish castles, it still does not reach people. The forums discuss the castles KALE, ORNEK, TURKEY, FAIN for good reason. They stand on the door, they are sold and bought. What is the cause of the demand? I think the following components: low price, red color of the lock box and shiny bolts. People love the red color and what glitters.

But seriously, I show in the pictures how to hack any of the above listed models of locks. In the photos there will be one of them - KALE, but others are the same. I checked it myself.

Guide for unlocking locks

In the first photo, the appearance of "everyone's favorite castle", on the second, the most simple version of cracking with a Phillips screwdriver, although a screwdriver must enter quite deep into the keyhole. Strangely enough, but this castle was really unlocked with this screwdriver without much effort, which surprised me a lot. I was preparing for serious work. And that's why another lock was unlocked here like this "rolled up".

Guide for unlocking locks

You see, the "coagulum" in the cross section is square, it is sharpened under the cone, it is convenient to insert it deeply into the key hole, a handle bent by 90 degrees facilitates the locking of the lock; in addition, a metal rod can be inserted into it to increase the lever. But I prepared very seriously. I still had two more rolls made on specials. Order, specifically for breaking locks with a cylinder mechanism with three rows of pins. The working part of these "rolls" was thermo-hardened. I began to look for a suitable lock. The Turkish are all broken, but there is also a KERBEROS lock of Russian manufacture, with a cylinder mechanism with three rows of pins made in Italy.

Immediately surprised that the lock of a low price group, but it is made very soundly, massive deadbolts made of thermo-hardened metal, the dead bolt clearance is 40 mm, the crossbar stand has protection against drilling, the design is simple and reliable. Well, I'll break it, although a bit sorry, the castle looks good.

Guide for unlocking locks

I inserted the key from the other lock into the lock and tried to turn it with pliers, did not work, broke the key. The mechanism of the lock did not suffer at the same time. The cross-head screwdriver was immediately put aside and decided to test specially made "rolls". The result of the tests you see yourself.

Guide for unlocking locksGuide for unlocking locks

I did not have a force measuring device with which I tried to turn the cylinder mechanism of the lock, but, believe me, the efforts were great. As a result of the tests, I broke both the "rolls".

Guide for unlocking locks

This device did not justify itself either. In search of a reliable cracking tool he took a tetrahedral file, sharpened the end under the cone on the emery, drove into the hole for the key to failure, attached the lever to the file and turned it in the cylinder mechanism. However, the castle was not unlocked. After that, by studying the cylinder mechanism it is established that the file cut off the projecting corners and started turning, but the pins were not touched, because Drowned deeply enough. The lock is still unlocked with a key. If there is an "unbelieving Thomas", visit St. Petersburg, Primorskiy pr., D.29, I installed this lock on one of the offices.

Guide for unlocking locks

Even after all efforts, the castle was not unlocked. Cylinder mechanism of the lock, as you can see, almost did not hurt, the outer projecting parts broke, but this did not affect the operation of the mechanism. For the given lock the above-described methods of breaking were powerless.

Conclusion: not all locks of this species are the same. I hope that the manufacturers of the KERBEROS lock are not very offended, that I put it on the test in a row with the Turkish.

The essence of the method is the following

The essence of the method is as follows. If you leave the key in the lock lock on the inside of the door (and as practice shows, the majority comes in), then with the key left in the lock, you can easily take a mold with plasticine or a similar material. And the next day, when you leave for your business, the thief will quietly open your door with a duplicate of the key. At the same time, the police, who arrived on your summons on the fact of burglary, states that the lock does not have any damage and is opened by "selecting the key". Experts know that it's almost impossible to just pick the same (other) key to the normally made lock locks. The actual number of combinations of lock locks Cisa, Kerberos and some others exceeds 200 million options. Thus, it is impossible to bring a car with keys, and it is very difficult to adjust the key to the lock in place, although there is a method of "deformation". This method is complex and not every thief is available in complexity and duration. Of course there are locks released with violations of technological manufacturing modes, with increased gaps on the code slot between the tooth of the toothing and the crossbar. There are locks deliberately released with the same combinations of options on the keys due to the low level of technological equipment and the desire to reduce their costs at cost. It is not difficult to find a key for such a castle. But the thieves, in addition to the existing unlocking of the locks, have developed new reconnaissance-combining places of theft with the removal of a fingerprint from the key. So how do thieves open the castle without leaving traces on the castle?

This method requires clay, a bit of a liquid oil, a metal plate about 10 cm long, about 0.5 mm thick, a width equal to the width of the key beard, and for example a clerical awl. At my fingertips there was a metal ruler (see photo 1), which I finished on the emery to the right size and for not having sewed, cut part of the electrode.

Guide for unlocking locks

Photo 1. The tool with which you can make a cast from the key left in the lock from the inside of the door.

Technique of making casts from the key left in the lock on the inside of the door:

  1. On the metal plate, it is necessary to roll up plasticine, in order to obtain a layer about 1-1.5 mm thick.
  2. On top of the clay, lubricate with oil, so that it does not stick to the key beard.
  3. We look into the keyhole and see the key, working (raising or lowering) the awl through the keyhole on the right or left side of the key beard, slightly turn the key, so that a sufficient space is left to push the plate with plasticine.
  4. We push the inside of the lock under (or above) the key of the key plate with "plastered" on it with plasticine.
  5. We remove the awl, the key returns to the horizontal position under the influence of the springs of the lever and the key beard is pressed against the clay, leaving its imprint there.
  6. To get a good impression, you need to press the key again with the awl with the key to the clay, acting on the right or left side of the key beard, as you prefer.
  7. After the key beard was pressed against the plasticine and the impression was made, the same procedure is repeated with respect to the second key beard.

And if we know a manufacturer who produces locks with a symmetrical combination, then one impression is enough, because The second half of the key beard is obtained automatically by direct or inverse symmetry. On the keys of the company Mottura, Sekureme, Atra and others and their Russian counterparts Class, Gerion, Chisa-Elbor, where the construction of the code mechanism of 6 beads with a double key bead is used, it is enough to take the impression once, since always having received one impression, It is easy to obtain and second by the inverse symmetry. With a certain skill and training, the time taken to take the impression takes less than a minute.

Photo 2. The photograph fixes the process of removing the impression from the key. In this experiment, you see the CERBER lock. It was on it that thieves were caught. Manipulating the right hand with an awl or other thin hard object, with your left hand, slip the plate with plasticine.

Photo 3. In the photo you see a clear impression that you can make a key with, without having to have the right key blank and file. This procurement is easy to buy in any key workshop for a penny.

If the key is symmetrical, in most of all locks, then it is enough to remove the impression once from any half of the key beard, if the key is not symmetrical, then it is necessary to shoot the impression from two halves.

Theoretically, in this way, it is possible to take a snapshot from the key of any key lock with a through hole that is not protected (not closed) for the key. Avoid thefts committed in this way easily. It is enough not to leave the key in the lock at all. Came, closed the door, and MUST pull the key out of the lock. This little trick and knowledge will help you avoid big trouble. As I already said: "Do not show the key to anyone, do not leave it without supervision, do not leave the key in the lock."


Now I will talk about ways to unlock the lock locks with the help of a "roll". Convolve (thieves' slang) is a special device for breaking the locking device of the lock in order to move the crossbars to the unlocked position. About the rollers for breaking the cylinder mechanism of the lock, I already wrote, and now it's the turn of the lock locks.

At us in the market there was a huge quantity сувальдных locks, both domestic, and import manufacture. Independently to understand which of the locks is better, it is very difficult, if you are not a specialist in this field. To save you from thieves and save your money when buying a lock, I write these lines.

In the laboratory, the following castles were tested: Cisa-Albor, Class, Cerber, Mottura, Kerberos, Mettem and Senate. But in order not to load the article with illustrations, I broke it into two parts.

The experiment began with the fact that the turner Uncle Vasya, with the help of a mat and a lathe, in just half an hour and a bottle of vodka, made a roll on a sketch. That's actually he (svertysh, not Uncle Vasya).

Guide for unlocking locks

Material of which is made of coarse - simple steel Ст.45. The thickness of the rod was chosen to be 8 mm. For durability. But if the coil is "hardened" (heat-hardened), then the rod can be made thinner, although, running ahead, tests showed that its strength is sufficient with a margin. The technique of possession is as follows. The key hole is drilled with a 8 mm drill, then a roll is inserted into it and rotated with a wrench, if necessary, a lever can be used. In our case, we used a torque wrench to determine at what effort the unlocking or breaking of the lock occurs.

Guide for unlocking locks

The photos show the sequence of actions. The castle Cisa-Elbor (article 1.06.61) was exposed to a curl on the shank of the bolt. With an effort of 10 Nm, the crossbar strut broke at the fastening point. The lock is loosened by the one-sided arrangement of the screed with respect to the shank of the bolt and the fact that the crossbar is welded to the shank of the bolt. The next three turns take place without effort.

Guide for unlocking locks

Castle Class. The picture is the same: with an effort of 10 Nm, the crossbar strut broke in the place of attachment (welding) and the lock was unlocked effortlessly. Disadvantages of the lock - a one-sided arrangement of the screed with respect to the shank of the bolt and the fact that the crossbar is welded to the shank of the bolt.

Guide for unlocking locks

Castle Mottura (article 52.771). At an effort of 10 Nm, the shank of the bolt shank collapsed due to "loosening" holes. The lock remained locked. However, you will have to change the lock to a new one. Service Mottura in Russia is not, sales of spare parts is not made. Taking into account the size of the Mottura lock, the MES "Bulgarian" will turn the entire door on an area of ​​almost half a meter square, which will add to the cost to the owner almost as much as with ordinary theft. In general, an effort of 10 Nm is not enough for the reliability of the lock, especially for such money.

The castle of Kerberos (article 111.11.011). For the tests, five locks, previous modifications and now manufactured, were taken. All of them behaved with dignity. None of the castles was unlocked. Although I "tormented" castles mercilessly.

Guide for unlocking locks

Initially, he closed the lock for four turns. At an effort of 56 Nm, the extreme tooth of the comb of the shank of the bolt bent, see the photo mark 1. The lock remained locked. I disassembled the castle. Suvalds practically did not suffer, it can be seen in the photo. The crossbar is securely pressed and not deformed. I decided to check, and what will happen if the lock is closed for two turns of the key? He assembled the lock, inserted a roll, turned it. At an effort of 42 Nm the tooth of the comb of the shank of the bolt was deformed, see the photo mark 2. The lock remained locked. Advantages of the lock is that the toggles are located on both sides of the shank of the bolt, the crossbar is securely pressed into the shank of the deadbolt and is made of heat-strengthened metal.

From the tests carried out it is clear that they will securely protect your apartment from a thief with a roll, only locks Mottura and Kerberos. At the same time the price of Kerberos is about 15-20 euros, and the cost of Mottura is more than 200 euros. Service of the castle of Kerberos in every city of Russia. Motura is good, but in Italy. In the future, when the doors are opened by rescuers of the Emergency Situations Ministry and the lock is replaced, the area of ​​the door damage in the case of the Kerberos lock is almost three times less than the area with the Mottura lock. Accordingly, three times less is the expense of repair and replacement. At the same time, Kerberos clearly (in FIVE WITH HALF TIME) outperforms Mottura by the force of counteracting the coagulation of the comb (56 Nm at Kiereros, against 10 Nm at Mottura).

To write this article I was enraged by a series of burglaries, where locks were unlocked with the help of such a roll. Thefts are not disclosed and the thief is still at large. Decide how to protect yourself from theft, using simple and easily accessible thieves' devices, known from time immemorial to all thieves. In the next article I will explain the thieves' technique of unlocking lock locks with the help of a roll on examples from life.

Continuation to the first part

If in the first part I demonstrated that many locks can be opened with the help of a roll ("the bear", "the collarbone" is the one who likes it more) in the laboratory, so to speak for cognitive purposes, but now I have taken examples from life.

It's no accident that they are castles "METTEM". The quality of the manufacture of the castle as a whole and its individual parts in particular allowed the thieves to easily enter the apartments with the help of a simple device - a roll. Thieves' technique is different from what I described in the first article. The thief does not drill a hole in the keyhole; This creates noise, even if the battery-powered drill. The thief comes in easier. It expands the opening of the keyhole with a mount, making it sufficient to insert a roll. And then he turns the coot and opens the lock. All this takes about two minutes (tested experimentally).

Why is METTEM good for a thief? Everyone. Namely:

- The body (box) of the lock is made of thin steel, which makes it easy to expand the keyhole.

- one-sided arrangement of the arms.

- weak fastening of the crossbar. By the way, I note that the crossbar is made of "raw" (sorry, critics for the term) steel, i.e. Not thermo-hardened.

But I will be honest and unbiased until the end. It was so easy to unlock the lock and it was also possible that in the door the key hole was round, with a diameter greater than the width of the keyhole in the lock. This is a big minus to the "door" (these are the people who make us doors). And this is a minus not just one separate office for the production of metal doors, this is more likely a rule, since I have a "wagon" of locks opened in this way.

And so illustrations.

Guide for unlocking locks

You see the lock METTEM article 3VSP-06. For especially cautious critics who write that I deliberately break locks and frighten people, I note that in the upper left corner of the castle you can see the number "1179". This is the number of the examination, which was carried out for this lock in the 25th department of the ETC of the Central Internal Affairs Directorate of St. Petersburg. I made this inscription so as not to confuse the locks (and there are a lot of them).

After removing the cover of the lock box, it is seen that the crossbar strut is broken at the attachment point. Red arrows and numbers marked:

2 - hole for the crossbar.

In the lock there is a thick grease, but one is already covered with a thick layer of rust (in the photo, the upper right).

For the rancor, I say that I do not teach thieves to "open" locks, they can do it themselves. And while telling and showing techniques of criminal unlocking and breaking of locks, I teach honest citizens how to protect themselves. If at least one person after reading my articles thinks about the safety of their apartment and places a good lock in a secure door and surrenders the apartment to the protection of the Private Security Service or a similar private security company, he will save his nerves and money, and the police will have less work and I did not waste the money Their personal money and time. These articles I regard as the prevention of violations, in particular apartment theft.


I bring to your attention several examples of criminal "autopsy" of castles. One of the easiest methods is to drill the cylinder head pins or the bolt shank in the lock locks. Factories manufacturing locks take measures against this, such as:

  • Covers for cylinder mechanism of thermally-reinforced metal (for example, locks "ABLOY").
  • The shank of the bolt shank is of thermally-reinforced metal.
  • Insert the steel ball into the end of the post of the shank of the bolt in order to move the drill to the side.
  • The mounting plates of locks made of heat-strengthened metal are manufactured.

However, there are ways to bypass protection. For example:

  • Lining of heat-strengthened metal can be drilled using special drills.
  • The protection of the bolt shank post with a steel ball can be bypassed by drilling a hole at an angle to get into the bottom of the post.

Now, high-strength drills have appeared on the market. The tests of these drills were carried out in the laboratory of the factory "Locks and Hardware" . Here is an illustrated example of drilling with such a drill.

There is no barrier to thieves?

Well, you installed good steel doors and reliable locks, and you think that you can safely leave the apartment unattended? Do not rush to entertain yourself with the thought that thieves will not reach you. Consider several ways to enter the apartment, bypassing the front door.

Method 1.

Do you live on the first floor? Then you do not need doors, you can go through the window. In the window of the thief penetrates for a few seconds, no one is afraid and not embarrassed. Because of the arrogance of criminals, everyone thinks that a person climbs to his home, forgetting the keys or breaking the lock.

If you live on the last floor, then you can jump from the roof to the balcony or go down the rope to the window sill and enter through the window. This at first glance seems complicated, but in reality it's a trifle. And no one will see. How many people go with their heads up?

There are several ways how to break glass silently. The simplest, which has been used for a long time, is to paste a wet newspaper on the glass and break the glass. Fragments stick to the newspaper and do not crumble. Now just stick a self-adhesive film and squeeze out the glass. A few seconds of work and no noise.

On the second floor you can climb on the grill, installed on the windows of the ground floor, or, from the visor of the entrance. In my practice, there were cases when thieves climbed to the second floor of the ladder, which was carried with them. It often happens that a thief, descended from the roof onto the balcony of the last floor, descends downwards, hanging on the balcony (with an increase of about 180 cm, his legs will just reach the railing of the lower floor). There are examples when thieves climbed from the lower balcony upwards, standing on the railing and reaching out to the upper balcony, but good physical preparation is needed. The first floors are most loved by thieves, because Even an unqualified thief can easily enter the apartment if there are no bars on the windows. It is enough to walk around the house in the evening, to see where the light does not burn on the first floors and when it's quite dark, throw a stone at the window to break both glasses and then hide. His accomplice from outside will look after the reaction of neighbors, then - whether the police will come and, if everything is quiet, podsadit friend in the broken window. Conclusion - the grilles will add to you a share of tranquility.

Method 2.

Do you live not on the first and not on the last floors? Do not relax. If you have strong doors, then you can break the door of a neighboring apartment and move from your next balcony to yours, and then to the apartment. Climbing to a neighbor from the top floor, it is easy to descend to your balcony.

Method 3.

This method is applicable in block houses, where a garbage duct runs along the stairs and there is a window to the street from the site, so, from this window it's very easy (less than a meter) to go to the window sill of your kitchen. And it can be done on any floor. In St. Petersburg, these houses are called "Ship" (because of the large length, more than 20 entrances). The method is very common.

Method 4.

A somewhat exotic way, but nonetheless, existing. Having penetrated into the neighbor's apartment, less fortified, they break through the wall into your apartment. In my memory, the case when the thieves rented an apartment in the neighborhood with a collector of antiques and slowly prepared the wall for a break. As the victim later said: "I heard a noise, but I thought neighbors are doing repairs." The antiquarian was away for an hour, the wall fell, and the thieves stole a valuable collection.

Method 5.

From the basement you can break the floor into the ground floor apartment.

Method 6.

From the attic of the house, the ceilings of apartments on the last floors are broken.

In continuation

In continuation to the first article on the methods of criminal opening of castles. In the previous article, the examples showed how to easily and quickly drill the armored pads on locks of eminent firms with the help of drills DIN 338. Below I will tell you how to open almost any lock, by examples of all known locks of the firms KALE, MOTTURA, CLASS, ELBOR.

The theory of preparation for burglary by drilling is as follows. Go to the store, buy the most common locks of the above companies. Next, install the lock on the door (say in the kitchen) and start to study it. Having dealt with the mechanism of the lock, make a stencil (a simple tracing paper is suitable), on it note the points of fastening of the lock and the keyhole. The binding is made to the keyhole; It is always visible from the outside of the door. Next, on the tracing paper, mark the point where it is necessary to drill a hole.

If it is a lock with a cylinder mechanism with one row of pins, then for its unlocking it is necessary to drill out the pins of the cylinder mechanism, below, using the example of the KALE lock, you will see how it is done. Typically, this hole is below the keyhole (if the pins are located below). A drill with a diameter of 5 mm is enough. After the hole is drilled along the length of the cylinder mechanism, hook or clip, through the keyhole, lower the pins, then insert into the keyhole any key (screwdriver) and unlock the lock. Elapsed time is 1.5 minutes.

Guide for unlocking locks

If it is a lock with a cylinder mechanism with three rows of pins, then it is enough to make one hole, raise the stopper and push the bolt off the hook. The stopper is in the depth of the cylinder mechanism, it is necessary to insert a similar key as far as it will go. Elapsed time is 1 minute.

Guide for unlocking locksGuide for unlocking locks

If it's a consignment lock . Drilling with a conventional drill to the point of attachment of the stand to the shank of the bolt (on the template, this place is marked, apply a keyhole to the keyhole and drill). Drill the rack and open the lock with a crochet (simply by sliding the crossbar) or by keying the key through the keyhole. The time spent is 3 minutes. Here is an example on Castle Class, but the same with Elbor Castle.

Guide for unlocking locks

It is not harder to cope with the castle Mottura. We drill the rack in the place of attachment to the shank of the bolt (at an angle, i.e. bypassing the rack from drill). The time spent is 5 minutes.

Guide for unlocking locksGuide for unlocking locks

If, say, I publish templates for the most popular models of locks of the most famous firms, then the child will be able to open them, armed with a drill and a piece of steel wire. I write this all so that you understand that you can not completely trust the locks and doors. Set the burglar alarm and the time taken to unlock your door will increase.


I am often asked questions about how to make skeleton keys, how to learn how to unlock locks with skeleton keys. I will answer, why do it, they have already done it for you for a long time and have set up industrial production. All the master keys that you see in the photographs are manufactured abroad in an industrial way. Their purpose is very diverse: they are for the police, for rescuers, firefighters, etc. However, they are available for free sale and everyone can buy them. Sets of master keys can be ordered through the Internet.

You see the picklocks that are used to unlock the locks with the cylinder mechanism, they are also called locks with a profile cylinder. These are locks that unlock most easily, so I recommend starting training with these locks. Learning to use them is very simple, for this, only it is necessary to imagine how such a mechanism works. The principles of operation of different types of locks are very graphically presented on the site of the "Hardware and Hardware Factory" where there are professionally produced flash movies showing the operation of locks. Below, photographs of single master keys and sets for unlocking locks with a cylinder mechanism with one row of pins are given.

Guide for unlocking locks

The principle of unlocking is as follows. In the keyhole, the "G" -shaped plate (they are visible in the photographs) is inserted into the top part and is created by means of its tightness (rotation) of the cylinder. But the cylinder does not turn; The spring pins prevent it. Next, the key hole is inserted into the keyhole and the pins alternately begin to lower, without loosening the interference. At the same time, at some of the moments when the pins are drowned, there will be a small (millimeters) fraction of the rotation of the cylinder mechanism. Because of the error in drilling holes for the pins, and it is always, even in the most expensive locks, one (or several) pins when lowering, "hang out", i.e. Do not interfere with the rotation of the cylinder, then, by clicking on the remaining pins in stages, we lower them all on the line of the rupture (the pins consist, as a rule, of three parts) and rotate the cylinder one turn, then the operation is repeated again. You read this much longer than unlocking the castle. Of course it's better to see once.

Guide for unlocking locks

But this is a mechanical "pistol" for unlocking locks with a cylinder mechanism, they can already unlock cylinders with two rows of pins. The principle of his work is the same. A "G" -shaped plate is used to tighten the cylinder, insert a master key into the keyhole, which is fixed to the end of the "gun" and, by clicking on the "trigger", we hit the pins. When they fail, the cylinder rotates. "Pistol" has the adjustment of the amplitude of the movement of the master key, and the frequency of the strokes is adjusted by hand.

Guide for unlocking locks

Well, these are electrical devices, the same as a mechanical "gun", but for lazy ones they work on batteries. But in fact, it is much better than a mechanical analog, because it allows you to manipulate the master key in the key hole finely.

I myself used all these devices to unlock the locks. By the way, the training began only when I got a mechanical "gun" in my hands. After that, I had an interest to unlock the castle with an old, "grandfather" way. I will say so, I unlocked the locks only for fun and in class with my experts and began to do it in a matter of seconds. The truth I unlocked the old domestic castles (they did not differ in the accuracy of production), but the current Chinese (including APEX). Well, now think, for how many seconds does a thief open your door?

Yes, you will be circumvented by the side!

Method one:

Two clips are taken, the first is completely unbent, and folds in half. After that, one half of it is bent several times, so that the bends form between each other no more than an acute angle, as shown in Scheme 1.

Then you need to determine which side of the cylinders are located - Scheme 2, and insert the manufactured master key to the keyhole into the keyhole, bent the side to the cylinders and try to turn clockwise, with sharp but careful movements, trying not to bend. If the attempt fails, repeat the entire operation again, but so that the "pattern" of the master key produced does not match the previous one.

Some useful tips:

Always watch from above or below there are cylinders, from this it usually depends in which direction to turn the master key. For example, if the cylinders are above, as indicated in Scheme 2, then the master key must be turned counter-clockwise, and not vice versa. This type of locks are usually installed on office furniture (on drawers, cabinets, etc.). If the master key is not suitable for the lock you are currently opening, do not throw it away. It can still come in handy, you do not go to this castle, you will come to another. For these purposes, I advise, to get you a special purse or something like that, where you will put up the picks you made at your leisure (you always carry this purse with you, just in case, there are cases because there are different cases).
