Is it possible to make keys by cast. How keys are made

On August 19, 2004, the "Television Security Service" (TSB) of St. Petersburg showed a story in which it is said that a group of thieves was caught, engaged in thefts from apartments very original way. In order to explain this thieves' method in more detail, I decided to make illustrations with descriptions.

The essence of the method is as follows. If you leave the key in the lever lock with inside doors (and, as practice shows, most do), then a cast can be easily removed from the key left in the lock using plasticine or similar material. And the next day, when you go about your business, the thief will calmly open your door with a made duplicate key. At the same time, the police, who arrived at your call on the fact of a burglary, state that the lock has no damage and is opened by "key selection". Experts know that it’s almost impossible to pick up the same (different) key to normally made lever locks. The real number of combinations of Cisa, Kerberos and some other lever locks exceeds 200 million options. Thus, it is impossible to bring a wagon of keys with you, and it is very difficult to fit the key to the lock on the spot, although there is a method of "removing deformation imprints." This method difficult and not every thief is available in its complexity and duration. Of course, there are locks produced with violations of technological production modes, with increased gaps on the code groove between the lever tooth and the bolt post. There are locks deliberately released with the same combination options on the keys due to the low level technological equipment and the desire to cut costs at cost. It is not difficult to find a key to such a lock. But thieves, in addition to the existing unlocking of locks, have also developed new ones that combine reconnaissance of the place of theft with taking a fingerprint from the key. So how do thieves open a lock without leaving marks on the lock?

For this method need some plasticine 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. I found a metal ruler at hand (see photo 1), which I finalized on sandpaper to the right sizes and for not having an awl, he turned part of the electrode.

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

The method of taking impressions from the key left in the lock on the inside of the door:
1. Roll out plasticine on a metal plate to make a layer about 1-1.5 mm thick.
2. Lubricate the plasticine with oil from above so that it does not stick to the key beard.
3. We look into the keyhole and see the key, acting (raising or lowering) with an awl through the keyhole on the right or left side of the key beard, slightly turn the key so that there is enough space on the left to push the plate with plasticine.
4. We put a plate with plasticine "smeared" on it inside the lock under (or above) the key beard.
5. We remove the awl, the key returns to horizontal position under the influence of springs, the lever and the beard of the key are pressed against the plasticine, leaving their imprint there.
6. To get a good impression, press the key against the plasticine again with an awl, acting on the right or left side of the key beard, as you prefer.
7. After the key bit has been pressed against the plasticine and an impression has been obtained, we repeat the same procedure for the second key bit.

And if we know a manufacturer that produces locks with a symmetrical combination, then one impression is enough, because. the second half of the key bit is obtained automatically by direct or reverse symmetry. On the keys of the company Mottura, Securem, Atra and others and their Russian counterparts Klass, Gerion, Chiza-Elbor, where the design of the code mechanism of 6 levers with a double key bit is used, it is enough to take an impression once, since always having received one impression, it is easy to obtain the second one by inverse symmetry. With a certain skill and training, the time of taking an impression takes less than a minute.

Photo 2. The photo shows the process of taking an impression from the key. In this experiment, you see a CERBER lock. It was on him that the caught thieves specialized. Manipulating right hand with an awl or other thin solid object, slip a plate with plasticine with your left hand.

Photo 3. In the photo you see the resulting clear cast, according to which it will not be difficult to make a key, having at hand the necessary key blank and needle file. This blank is easy to buy at any key workshop for a penny.

If the key is symmetrical, in most of all locks, then it is enough to take a cast once from any half of the key beard, but if the key is not symmetrical, then you will have to take a cast from two halves.

If the key is symmetrical, then it is enough to take an impression once from any half of the key beard, but if the key is not symmetrical, you will have to take an impression from two halves.

Photo 4. In the photo you can see the process of taking a cast from the Mettem lock, where an asymmetrical method of cutting combinations is used.

Photo 5. In the photo you can see the resulting cast. Because the key is not symmetrical, it is necessary to take an impression from the other half of the key beard.

Photo 10. In the photo you can see the process of taking a cast from the Cisa-Elbor castle.

Photo 11. In the photo you can see the resulting cast.

Theoretically, in this way it is possible to take an impression from the key of any lever lock with a through unprotected (not closed) keyhole. It is easy to avoid thefts committed in this way. It is enough not to leave the key in the lock at all. Came, closed the door, and ALWAYS remove the key from the lock. This little trick and knowledge will help you avoid big troubles. As I said: "Do not show the key to anyone, do not leave it unattended, do not leave the key in the lock."

May troubles pass you by!

There is nothing worse than losing the last key! The failure of the lock or the breakage of the key is an unpleasant situation that every person must have fallen into. And if the intercom key can be copied by taking a sample from a neighbor, then unlocking devices from own house can be made from the original. But what if the key is lost, and this was the last copy? You can make a key according to the lock - a popular service, in demand in many cases, is offered to Muscovites by our workshop.

Duplicate without original: it's not a myth

A few decades ago, the loss of the last copy of the keys made it almost impossible to manufacture a new unlocking device. But progress does not stand still, advanced technologies offer a painless way out of a seemingly hopeless situation. Making keys according to the lock does not require the original key, the skills of the master and specialized equipment are enough. It is far from being in every tent, so you should not trust the security of your personal space to unverified companies. Our company is equipped with modern machines that allow you to make a key for a lock, the price of which will not hit you hard. family budget. In this way, you can make a device for any lock.

Can't find the key? Making keys for a lock

There are two ways to make a key: bring the lock to the workshop yourself or invite a specialist to the site. The first way looks problematic - the tools are probably at home, where you cannot get. But the second way is quite real: one has only to call the World of Keys company, and our master will arrive at the scene. Making a key according to the lock at a price differs from the production of a duplicate of the original, the cost is affected, first of all, by the type and degree of security of the lock itself. In some cases, a local specialist may offer to replace the closing device with a similar model with a sealed set of keys. In other cases, you will have to go to the workshop.

• Work is carried out as quickly as possible, in the presence of the customer.
• We will help with the installation of the lock, check the performance of the keys.
• The number of duplicates is not limited, we work with any brand of locks.
• Reasonable prices and discounts for regular customers will be a pleasant surprise.
• All products made in our workshop are guaranteed.

Making a key for a lock is cheap and with a guarantee - one of the most necessary and useful services for the population. Not every workshop takes on laborious work. This process is not as fast as the production of a duplicate of the original. For maximum matching of the larva and the key, professional jewelry work and modern equipment are needed. Fortunately, our company has both. By entrusting the production of the key to us, you will quickly receive a high-quality product that will not cause the slightest difficulty during operation.

How to make do-it-yourself intercom keys? Before thinking about this question, you should first find out what keys, blanks, duplicators are, how they are arranged and what they are.

What is a universal key for intercom?

You need to start with the fact that there are several types of intercom keys. This can be either a contact “tablet” (usually the electronic media is attached to a special holder), or contactless key fobs, cards or magnetic keys, as well as two-contact keys, which are really rare. Each of these keys contains a certain code that is entered there during manufacture.

Is it possible to make your own?

It is rather difficult to make a universal key for an intercom on your own, simply because there are no completely universal keys. There are some exceptions to this rule. Indeed, one magnetic key for an intercom (for example, from Factorial) can fit all the entrances of the house or coincide with any of the houses on the other side of the city.

Manufacturers may not really care about the difference in firmware, since in fact such matches are only a fraction of a percent of the real number - one or two, rarely more entrances in the whole city. There is also a universal tablet for opening intercom locks, but again, this greatly depends on what kind of manufacturer it is. For example, a universal tablet from Factorial will not fit locks from other manufacturers.

What is a key blank for an intercom?

The main technical characteristics that distinguish blanks are whether they are contact or non-contact. Also great importance has the fact whether it is possible to overwrite the code on the workpiece, or this opportunity is absent. In addition, there are really quite a lot of manufacturers of such blanks - they all differ in small details, as well as in the quality of production. Is it cheap plastic or expensive, for example. Thus, a magnetic key for an intercom can be very different from what you are used to.

What is an intercom key duplicator?

Duplicators can be both professional and the most primitive - legislation Russian Federation in this case is not violated, since such equipment is not affected. Such devices enable a person to read the code of the original key - in the future it will be used to make a new key, which can be done both manually and automatically.

The simplest duplicators can only work with the most common blanks, and therefore cannot be considered particularly useful, although this also provides some opportunities. But the quality of duplicates still leaves much to be desired, in addition, you will need to find out the brand and model of the intercom, and perhaps after several attempts you will still be able to make a key to the intercom.

Professional devices are much more useful. They have extended technical specifications, which results in very high quality copies. It may even seem to the uninitiated that with their help it is quite possible to create universal keys for do-it-yourself intercoms, but this is not so. This device allows you to bypass the filter and use the duplicate as a native key, but nothing more.

True, the optimal workpiece is selected automatically, which significantly reduces the likelihood of errors and various defects. Also, such devices keep track of the copies made, and these same copies will be guaranteed to serve as well as regular keys.

Production of intercom keys

To make them, you will first need to know its model. If you cannot do it yourself, then a professional duplicator will do everything for you. About what preparation is needed, it is worth learning separately - this information is in the public domain. On the Internet, it is quite possible to find compatibility tables for duplicators and blanks and avoid unpleasant excesses. Making keys for an intercom using a duplicator will take from a few seconds to several minutes. It all depends on your experience with such elements.

We make the device with our own hands

In fact, it is rather difficult to make universal keys for intercoms with your own hands - everything depends on the above problem about the general differences between all existing systems. It is realistic to perform such a task only to a person who is quite well versed in programming, and also has significant engineering skills. In general, making keys for an intercom is a rather laborious process.

If you have your own duplicator, then it is really possible to make a copy for one intercom. But in order to make a universal key for an intercom, you will need an emulator.

What is an emulator?

In fact, this is a device that allows you to open almost any door. It has its limitations, but it's still much closer to truly universal keys. In fact, just making a key to the intercom is not enough, write software- that's really hard. Although even with the best software and a high-quality emulator, any door will not open in front of you.

Here the problem lies again in the difference between systems and even models of intercoms from the same manufacturer. There is nothing difficult in setting up the emulator for one system, then the code will be selected according to a certain algorithm, which means that all intercoms of this brand will open literally at the wave of a hand. Everything becomes more complicated if there are at least two brands or two different schemes, this already means that there are two algorithms. This means that the emulator itself will have to understand which one to use in a particular situation, since there are not so many options for how to make an intercom.

Even despite this, it is quite possible to make keys for an intercom with your own hands. But to make them completely universal is still impossible. This is too serious a task even for a team of programmers and engineers, especially since electronic key won't open magnetic lock and vice versa. However, emulators for various systems it is quite possible to find it in reference books, and with experience or perseverance, it is quite possible to make universal keys for intercoms with your own hands. However, it will be easier to buy a factory duplicate.

Myths about intercoms

You already know that it is still possible to make a universal key with your own hands, although it is quite difficult. The result will, of course, be slightly different than expected. You can talk about some of the misconceptions of people about intercom systems:

• Intercoms do not have universal codes, only the Vizit system differs in this, where there really is a digital combination in the factory settings that allows you to open the lock without a key.
• Universal keys for intercoms simply do not exist - too different systems and the principles of operation of locks, so it will not work to open everything with one key.
• The intercom magnetic key cannot be demagnetized if put in a bag with a magnetic clasp or on speakers and so on. But it is quite possible to mechanically damage such a key, so careful handling should not be avoided.

So, we figured out how to make universal keys for intercoms with our own hands.

Keys are often lost. If they are from an important lock, then you will have to change it, because an attacker can pick it up. But what if there is no chance that someone will take possession of it, but you want to leave the castle? How to make a key for an existing door lock?

Is it possible to make the key yourself?

In any case, you need theoretical background. There are two types of locks: lever and cylinder.

Each has its own principle of operation. The lever type key has protrusions on the key, each of which raises the pin. If the pin and protrusions do not match, then you cannot turn the key and open the lock.

The key to the lever lock

Cylinder locks have secret mechanisms in the form of a larva. The key is equipped not with protrusions, but with notches. It is easier to make a key for yourself than for a key.

With a strong desire to make a key yourself is real. You need to understand the mechanism and principle of operation of the lock. Have a blank, but rather a few, because the first time it may not work. Some list of tools. Namely, these are files different sizes, vise. Plus, there's plenty of time to spare. If you have the skill, then making the key does not take much time. An amateur in this matter will need a lot of free time to figure it out.

Attention! If you need the key urgently, then do not torture yourself. It is better to take the core of the castle and take it to a specialist. The key is made by a specialist in 10-15 minutes.

You cannot make a key blindly without knowing how the lock cylinder is arranged. Trying to turn the case without removing the lock, you will spoil the secret mechanisms. So, you need to have full access to the secret mechanisms.

Consider the methods of making a key for a locked and disassembled lock.

Manufacturing by a locked lock

There is a need to make a key, and it is impossible to dismantle the core of the mechanism. This happens when the door is locked and you don't want to break it down. If attempts to open the lock with a master key or selection of a key were unsuccessful, then they try to make a suitable one on their own. It's complicated. Even if you arm yourself with special tools, a positive result is not guaranteed.

For manufacturing you will need:

• files of different sizes;
• needle files;
• blanks;
• vise;
• pliers;
• calipers.

It all depends on the type of lock. Perform actions carefully, without haste. Rough and excessive force will damage the mechanism.

• Insert the blank into the keyhole until it stops. If it does not fit, select a suitable blank. You don't need to force it. So you damage the secret mechanism of the lock.
• Rotate the blank without much effort. This can be done using pliers. AT certain moment the blank will rest, it will be felt. Swing it in different directions, turn it back to its original position and remove it from the lock.
• If it is not clear why the disc should be rotated, then the following steps will clarify. Necessary good lighting to inspect the surface of the workpiece. With proper light, traces from the secret parts of the mechanism are visible, obtained by rocking the blank when it rested against them. It seems that it remains to cut out the marked places with a file, but not everything is so simple. The number of grooves and recesses depends on the secrecy of the mechanism of the locking device. There are many marks on the blank. It is not enough just to remove them, you need to observe jewelry accuracy. An extra piece of the blank removed will not allow you to open the lock and you will have to start all over again.

The process is time-consuming, requires a certain skill and endurance. When cutting grooves, do not do everything at once. I made one recess, inserted it into the lock and checked. Etc.

Making according to the larva of the castle

If the key is not lost from a locked lock, then making keys from a larva is easier. Remove the core from the lock. Disassemble it. It is not difficult to do this. Remove the retaining rings on it and carefully disassemble into two halves. Be careful not to lose the small secret parts of the castle.

Choose a workpiece that is suitable in size in advance. Do not forget about this until you have dismantled the core. It is possible, as in the first case, to mark on the workpiece light movements secret places. The push-in method will damage the mechanisms.

So, on the blank there are marks from the crossbars and the lock is disassembled into two parts. Start gradually sawing out the marks and creating grooves. clean up excess metal file or needle file carefully, slowly. The disassembled locking mechanism will allow you to check the grooves by applying to the crossbars. Visually determine how much to remove and which grooves fit the shape of the crossbars.

The easiest way to make a mold is to use plasticine. If kids or schoolchildren live in the house, there will certainly be material. Additionally, you will need a little vegetable oil and a piece of metal plate 10 cm long and ½ cm thick.

How to make a key from a cast

How to make a mold of a key from plasticine? The sequence of actions is as follows:

Roll out a piece of plasticine on a metal plate so as to get a layer slightly thicker than the bulges of the key itself (from 0.6 to 1.5 cm);

Lubricate the surface of plasticine vegetable oil so that the beard of the key does not stick;

Press the key into the plasticine, first with one side, then with the other side.

This completes the work. But what if the key is lost? You can do without it if you do not want to change the lock. You need to buy a blank for the key and arm yourself with pliers.

How to make a cast of a key in a lock? It is necessary to insert the workpiece into the lock until it stops, clamp the head with pliers and turn the “opening” movement to the right as much as possible. Make several movements up and down. Turn the workpiece to the left to the very end and also make several vertical movements. When the workpiece is removed from the larva, internal pins will be clearly imprinted on it. It remains to cut off excess metal - and you get a great replacement for the old castle.

How to make a key from a cast

It is not enough to know how to make a cast of keys correctly. It is equally important to understand what to do with them next. It is difficult to make a key on your own: you need skills in handling a needle file. If the print is made directly on the blank, you will have to carefully cut off the excess metal, constantly checking the result. It is necessary to cut down all the interfering parts, round the corners and edges so that the key opens the door more easily.

If the cast is made on plasticine, work will begin with the manufacture of a drawing.

Here, too, special knowledge is needed: you need to make the most accurate drawing of prints.

To make a key using your cast, you need to cut out recesses, grooves, bends with a needle file, exactly following the drawing. All sharp edges need to be cut down, rounded off. There should not be any burrs either. It is important not to go beyond the boundaries of the drawing, not to cut off excess metal: this way you can ruin all the work. The key will be ready when it begins to easily unlock the lock.

Making your own key prints is very easy. But cutting a new key from the blank is not necessary: ​​you can simply take the casts to the workshop. But if you want to learn a new craft, you can try to cut the key with your own hands.
