There are many reasons why the lock does not open: breakage or loss of the key, clogging of the mechanism, sagging of the door leaf and others. Better problem entrust it to a specialist, but what to do if the technician is busy or the breakdown occurred in dark time days? You can solve the problem yourself if you understand the types of locks and their weak points. There are a few true ones household methods open if it is not possible to use the key.

If it is not known what type of mechanism the breakdown occurred with, you can take the following actions to open it (intruders often use these methods):

• Finding a key can only be done with a cylinder mechanism.
• Use a master key.
• Drill out - scrape off the pins and try to open them with a screwdriver.
• Release - move the door to the left and press (to secure the lock, you need to install a one-piece frame).
• Remove the fittings and try using a screwdriver.
• Acid is poured into the hole special substance, the door gives way.

If the key is lost, you should not try to open the lock with someone else’s, which at first glance seems suitable: it will most likely get stuck and the problem will only gain momentum.

Types of locking mechanisms and types of keys

To open a lock mechanism without a key with minimal damage, you need to understand the type of lock, its structure and then select the necessary opening method.

There are two types of locks installed on modern iron doors:

• Mortise - the mechanism box is installed in the middle of the door leaf (which partially disrupts it);
• Inset - differs from the first one in that the lock is installed before the doors are assembled.

As for the mechanisms used, the following are most often used in metal doors:

• Level plate - consists of plates that, when the key is turned, appear in a certain sequence (the more there are, the more reliable the device;
• Cylindrical (pin) - consists of blocks (washers, pins) that, when rotated, act on the crossbars and the door opens.

Pin mechanisms are divided into privacy groups:

• Low security (up to 10 thousand) - easy to open with master keys. Key type two and one-sided English (butterfly key), cross.
• Medium (up to 5 million combinations) – opens using the “punch card” type.
• High (more than 100 billion) - punched card and Finnish key.

The lever mechanisms are opened with a butterfly key. The degree of protection directly depends on the quality, and the quality, in turn, depends on the price.

Opening cylinder mechanisms

To begin with, we will talk about cylinder (pin) types of locking mechanisms.

The easiest way to open the “English key” type (butterfly key):

• Find a hairpin, paper clip or piece of wire and divide it into 2 parts.
• Bend at a right angle (the bent tip should fit freely into the hole).
• Using a bent wire, apply tension at the top of the mechanism in the direction in which the key turns.
• Use the straight part of the pin (wire) to lift all the pins in turn.
• Turn the bent part of the wire.

The same technique is used to pick a lock with a double-sided English mechanism, only in addition to the upper ones, you need to lower the lower pins.

The cross-shaped locking mechanism can be opened using a screwdriver. Algorithm of actions:

• Remove the outer part;
• Instead of a key, turn the screwdriver several times in the desired direction (to scratch off the pins).

The Finnish type of locking mechanism is one of the most reliable; it is not so easy to open, even with the help of professional master keys. If it is not expensive device, can be eliminated outer part mechanism, pull out the plates and then try to open it with a screwdriver. If the model is expensive, more radical measures are needed (for example, calling rescuers).

Hacking lever and tongue locks

Lever locks are very popular due to high degree reliability. To open such a mechanism without a key you need to:

• Find a similar key, a heavy object to hit;
• At 75%, insert the key, pull and strike.

It may not work the first time, but the method is reliable.

Another type of lever lock - single-row and double-row “laser locks” requires a different approach to solving the problem:

• Find a small metal plate, scissors (for metal), pliers.
• Cut something like a key from the piece and use pliers to make waves.
• Insert all the way;
• To turn.

The first method is also suitable for solving problems with a pump lock - it is often used to protect a garage or driveway.

There are more basic locks, but no less problematic when opened.

Lock with a tongue: you can use it like in the movies plastic card, but most likely the door will not open, and the card will break. It is better to use a metal plate, a screwdriver, or a flat rod - the main thing is that the device fits into the opening between the door frame and the leaf. If it works, you need to press down the tongue and push the door.

A lock with a latch can be opened in this way: remove the handle (you need to find a device to unscrew the bolts), remove the plate that hides the core of the lock. Then feel for the latch, press and turn the door handle fastening.

The key is broken: what to do?

There are disappointments in life: the key broke and got stuck in the keyhole. To solve the problem you need hands and a set of tools:

• The scrap is small.
• Screwdriver Set.
• Bulgarian.
• Drill.
• File.

This and other ways to open a lock in the video:

This is a complete set of tools to solve the problem. Perhaps all you need is a nail file or a screwdriver.

The process of removing a key using a jigsaw file consists of the following steps:

• Insert the nail file with the teeth facing up;
• Move slowly, prying off the key;
• Pull out the file with the key.

If after the procedure the lock still does not open, the mechanism may have been damaged.

If you come across a butterfly lock, in addition to the above-mentioned opening method, you can try this:

• Make a hole above the well using a drill.
• Neutralize the larvae.
• Press the hook on the mechanism so that the crossbars move inward;
• If that doesn’t work, you can cut them with a grinder.

If the door has gaps, you can use a screwdriver to pry it up, press it down, and suddenly it will give way.

Whatever happens, you shouldn’t try to get into the room through your neighbors’ balcony - it’s better to pay to call a locksmith if you can’t open it yourself.

If it happens that opening the lock with a key is not an option, then most likely the first thing that comes to mind is to knock down the door and contact a specialist. Both will cost a lot of money (for repairs or for paying for services); moreover, in the second case, you will need to provide documents confirming ownership or right of use, which is not always possible. Therefore, knowing how to open a lock without a key is useful for everyone.

To open a cylindrical lock, you will need a master key, which is most conveniently made from half a pair of tweezers (a piece of wire from a champagne bottle will do), and a lever (a narrow blade of a folding knife or a stiff piece of spring from an old telephone dialer). You can also order these devices in online stores in reserve. So let's get started. Insert the lever into the keyhole so that its “handle” is on the side in which the key turns when opening the lock. Use the finger of your left hand to press it down slightly. Now insert the pick into the very end of the hole, then press the lever harder. Next, actively make reciprocating movements with the master key, saying in simple language , “back and forth”, inside the keyhole, while gradually pulling the master key towards you and try to turn the lever. It may not be possible to pull it off the first time; your task is to concentrate and calmly achieve your goal. Padlocks on clothing cabinets are very easy to open using a paper clip. Bend the longest (outer) piece of wire 90°, then, stepping back 2-3 mm from the edge, bend the wire 45° (using pliers or inside scissors located closer to the fingers). Now insert the prepared paper clip into the lock until it stops and turn it as you would with a key. The lock will open immediately. Please keep this in mind when leaving your belongings in your locker while you work or exercise.

Try the methods described above on your locks in advance so that, if necessary, you are ready to deal with this problem yourself, at the same time you will test your locks: how burglar-resistant they are and whether it is worth leaving valuables while you are away, hoping for their strength.

Surely each of us has lost the key to the front door at least once in our lives. When you see a door in front of you that blocks access to a house or other room, you begin to think about how to get inside without a key. To make it easier to understand, you first need to evaluate the design of the door, because all models have different types locks Below you will learn about the most common methods for getting into locked rooms without a key. But at the same time, I would like to remind you that to successfully solve this problem you will need some experience.

Is it possible to unlock the lock with your own hands if there is no key?

If you are left without a key and urgently need to open the door, then there is no need to panic. Try to evaluate the problem that has arisen. After all, when the entrance is blocked by a flimsy interior door, it can often be unlocked without any special skill. But if you have to deal with a metal entrance door from a well-known manufacturer, then even a specialist will have to work hard. If you are not sure of success, then don’t waste time and effort and spoil the design doors using improvised tools. In such situations, it is recommended to entrust this work to professionals.

If a specialist takes on the job, he will be able to open a lock of any design. He is familiar with the features of many locking mechanisms, so it will not be difficult for him to unlock the door in an intelligent way, keeping the locking mechanism intact. Therefore, having decided to use the services of a specialist, it will not always be reasonable decision. Reliability of some models may be imaginary, and therefore if you have necessary tools, then you can open them quickly enough. We will talk about the most accessible of them further.

Opening the locking device of the interior door

How to open a lock without keys without the help of a professional? If you are dealing with an interior door, then opening it will not be difficult for you. Most often, such door blocks are equipped with locking mechanisms, the design of which includes a latch on one side and a part resembling a keyhole on the other. Considering that doors like these are rarely locked, owners lose their keys already in the first weeks or months after installation.

Often the door is locked due to the carelessness of small children. Once indoors, they may slam the door, latch it, and, contrary to the persuasion of adults, do not want to open the door. Naturally, parents are afraid for their baby, since he is left alone in the room. Because of this, it is important to open the lock as quickly as possible so that later it retains its working condition. You can solve this problem by performing the following operations.

• find the keyhole and familiarize yourself with its design;
• find a tool that is suitable for opening the lock;
• start opening the door, doing everything very carefully.

How to open locks of different shapes?

There are models of locks in which the hole has a round shape. In this case, to open it, it is best to find a thin knitting needle, a large open paper clip, an awl or a toothpick. Having decided on a suitable tool, place it in the hole, then press lightly with one hand and at the same time begin to release with your second hand or twist the handle. If everything is done correctly, the door will open.

The same should be done in a situation where the lock well has a flat shape. In order for you to be able to handle this lock, you will need to find a flat tool. For this purpose, you can use sharp scissors, a narrow-bladed knife, a nail file, or the handle of a teaspoon. Having selected a tool, you need to insert it into the well, then press it with one hand and at the same time with the other we begin to twist it and lower the door handle.

Unlocking a cylinder lock without a key

Greater difficulties can arise if the locked door is equipped with a cylinder lock. Considering the great secrecy of such locking devices, intelligent opening methods will not always help solve the problem. Although, with experience, you can get inside if you use a paperclip or a very thin, bent screwdriver.

If we talk in more detail about the intelligent method of hacking cylinder locking mechanisms, then here from a person required to perform certain actions paperclip and screwdriver, where the first will be used as a master key, and the second will serve as a roll. When trying to open a lock using similar methods, keep in mind that here the most important point- insert the hook into the hole so that the secret fonts take the correct position. They need to be placed one at a time, always helping with the roll. With due persistence, the larva will begin to sell. To understand whether the fonts are installed correctly, you need to visually evaluate their location relative to each other and focus on the sound.

Using a paper clip, you need to move all the pins one by one, helping with the roll. Moreover, each time you need to check whether the cylinder can be rotated. Only when it begins to give in will you be able to solve your problem. Please note that what sounds come from the well while working to open the lock. This way you can stop in time if you do something wrong. Otherwise, you may simply break it.

We use the rough method

If a homemade master key does not help you deal with the lock, you can resort to a more crude method of hacking. However, here there is one important nuance : you can count on success only if the larval lock does not have protection against rolling and drilling. If you decide to use this method, then you need to prepare the following tools:

• electric drill - preferably as possible more power;
• metal drill;
• thick flat screwdriver;
• hammer.

Immediately prepare for the fact that after using this hacking method you will need to install a new larva. First, try a powerful roller. To do this, take a screwdriver and place it in the lock as far as possible. You can even hit it a couple of times with a hammer. After that we begin to screw it on. Having realized that the larva begins to spin after the screwdriver, you need to pull the screwdriver and remove the secret. Once you do this, you will be able to get inside.

Opening a door with a rack lock

If after examining the doors it turns out that it is equipped with a rack and pinion lock, then you can calm down. Of course, with such locking devices sufficiently provided good protection from a rough break-in. However, if you use intelligent methods against them, you can easily defeat them. To make it easier to open such a lock, it must be lubricated, for which WD-40 is used. Next, you can choose any of the following hacking methods.

1. As a tool, you can use two flat screwdrivers with thin rods. Keep in mind that here you need to use screwdrivers that can be used together without special effort enter the castle hole. First you need to place one screwdriver inside so that you can use it to fix the notch of the bolt. Then you need to move it a little, after which you need to take another screwdriver and fix its position. After this, you need to perform the above steps again: find a new notch, move everything and move it with another screwdriver. We do this until the lock is opened.
2. We use a wooden wedge key. You may not have a wedge key. However, there is no need to worry about this. You can easily make it yourself. For this any soft breed tree, from which it is necessary to make a wooden wedge of suitable sizes. Next, take this wedge and insert it into the lock hole until it stops, using physical effort if necessary. After this it needs to be removed. When you examine the wedge, you will see notches on it, thanks to which you can modify it so that it looks like a real key.
3. We unlock the lock by pressing the door. Your task of opening the lock will be much easier if locking mechanism placed in such a way that the door leaf can be pressed out. To do this, you need to take a crowbar, place it between the jamb and the canvas, and then you need to try to squeeze it all the way. After this, insert a screwdriver into the created gap and remove the lock bolts to the side. The door will be open.

Most of us don’t know how to behave in a situation where the key is lost and we urgently need to get inside. Although experts know how to open door locks without damaging them, any of us can also solve this problem. There are quite a few quite easy to implement methods, allowing you to open the lock regardless of its design. Therefore, if you want to get inside yourself, try to do everything very carefully. If you do not have confidence in your abilities, it is better to consult a specialist.

Sometimes life forces a person to decide rather complex tasks. One of them is emergency opening door locks. There are different situations - the front doors may slam shut, in another case the keys may simply be lost. Also, the key sometimes simply breaks right in the hole. Those who found themselves in such a situation, being in a confused state, called the Ministry of Emergency Situations or used the services of specialists. But there are ways to open a door without a key and the need for someone’s services. We will conduct a short master class and learn how to open any locking mechanisms.

Main types and designs of lock mechanisms

So, the situation is that upon returning home the person realized that the key was irretrievably lost. In this case, people can act in different ways - some people try to knock down the door, others try to ruin the canvas or cut out the lock. At the same time, no one uses a set of master keys for opening - there is an opinion that this procedure is quite complicated. But basic set skills that are sufficient for hacking are available to everyone.

All door locks existing today can be divided into several types - padlocks, overhead locks, mortise locks and inset locks.

In this case, there is no particular point in considering padlocking mechanisms - they have not been used on entrance or interior doors for a long time. They are used only for doors to utility or other types of non-residential premises.

Overhead locks are used on wooden doors. They can be found on metal ones, but very rarely. The advantage of such locking systems is that when they are installed, the integrity of the door leaf is maintained. It is considered a minus appearance doors - with reverse side the rear part of the locking system is visible.

Mortise locks are already a popular solution for all types of modern doors. They are located inside the door leaf, which supports the mechanism and performs protective functions. These models are aesthetically pleasing and quite reliable. Disadvantage - it is necessary to violate the integrity of the door leaf frame when installing them.

And finally, the fourth group is the most good choice. At the factory where the door was made, the lock is installed even before the door block begins to be assembled. Main advantages – high level reliability, minimum damage to the integrity of the door leaf, beautiful appearance.

Now it’s worth considering the secret parts of the mechanisms. There are two popular types - lever and cylinder.

A lever lock works as follows - when a person inserts a key into the hole, the teeth of the secret magazine arrange the relief parts or levers in a certain sequence - the lock will turn only in this sequence. These mechanisms are considered one of the most reliable, and the level of burglary resistance depends on the number of these plates.

Cylinder locks work differently - the cylinder mechanism has pins that are aligned in height according to a certain pattern. Instead of pins, there can be anything - various blocks with the ability to rotate, washers, moving parts. During the opening process, the mechanism inside the cylinder acts on the crossbars through a special drive. This is how the door opens.

Classification of secret lock mechanisms

Cylinder locks vary in security level - the first group of low security can have up to 10,000 different combinations. Average level secrecy - up to 5,000,000 combinations. The maximum level is up to 100 billion different variations.

The first option is often manufactured with low precision. This mechanism is also practically not protected from the effects of master keys and is made of inexpensive materials. Chief Representative This group is the so-called lock with an English key. An experienced burglar can deal with such mechanisms in less than a minute. To an ordinary person The opening process takes a little longer, but it will cope with the task.

The second category is a high level of reliability. Here the pins are made with a high level of precision, and their arrangement is very complex. There are various protective elements here, and all parts are made of more durable materials. To open this mechanism, a professional will have to spend about 5-10 minutes.

The mechanism of the third category is equipped with all protective elements made from the most wear-resistant materials. The pins are arranged with maximum difficulty. This lock is practically unbreakable. The key is a “punched card” or “Finnish key”.

The lever mechanism is much easier to classify - here are single-bit or butterfly keys. The quality of locks and keys depends on the cost of the mechanism. Experienced burglars claim that if a mechanism has more than 6 levers, then it can be considered reliable. These systems have special protection against drilling; the keys are made with high accuracy– It’s very difficult to hack them, but it’s possible. Let's find out how it's done.

Opening a lock with an English key

This is done as simply as possible. Various pieces of wire, hairpins, and paper clips are suitable for this. Anything will do as long as it's made of metal and doesn't bend.

The first step is to prepare a master key. The paperclip should be bent at an angle of 90° so that the bent part can fit into the hole. Then the end of this segment is flattened - this should make turning easier.

The second wire should remain flat - you can only bend it a little at the edge. The result should be a small hook. You will need it when working with pins.

To open the lock, the first wire is inserted into the top of the keyhole. In this case, you need to pull it a little in the direction of turning the key. During the interaction of this master key, the cylinder should rotate slightly. Then the device is deepened to the very end and the pins are raised with wire. This must be done clearly, lifting one pin after another. When the process is completed and all the pins are raised, the lock will open with a slight movement.

We work with a two-way English key

The principle of operation in this case is the same as with a regular English key. The only difference is that here you will have to lower the lower set of pins.

How to open a door without a key with a cross mechanism

There is nothing easier than opening a lock with cross key. This mechanism is characterized by low secrecy - in various models that's only 600 to 1000 possible combinations.

To work you will need a Phillips screwdriver. It should be pressed firmly into the well and simply cut off the pins of the secret mechanism. Metal doors With locks of this type, opening is simply elementary. This is an example of when a lock spoils a good and reliable looking door.

"Finnish" keys

These locks are difficult to pick using master keys. In this case, it is much faster and more accurate to dismantle the outer cover and remove all the insides. Then the mechanism can be easily turned using a screwdriver.

Locks are different, and this is not possible with every mechanism. However, everything will work out with Chinese and domestic ones.

Level locks

Here the opening principle is slightly different. You need any lever wrench except the “butterfly”. Next, you should make an L-shaped master key. One by one, the levers need to be lifted with this “tool”. When all the plates are raised, the key can be turned. These operations must be repeated until the door opens.

other methods

You can fight locks with homemade master keys - the locks open quite successfully. But if you don’t have time or something doesn’t work out, then you can simply drill out the secret, and then the mechanism will open with a simple screwdriver.

The second working option is to simply knock out the lock. To do this, you need to hit the cylinder quite hard with a hammer. Hit with such force as to break the internal joint responsible for turning. If this part breaks along with the screw that holds the cylinder, all that remains is to pull out the cylinder and open the lock with a bent wire or knitting needle.

Of course, working in this way, the locking mechanism can then simply be thrown away - it will no longer be able to perform its tasks. But it will still be possible to get into the apartment or house.

How can you close the door if there is no key?

It all depends on the type of lock. There are no problems with systems that slam shut. With others, the task of closing the door is more difficult. But nothing is impossible.

If the lock has a handle that moves down or up, then any metal pipe will be needed. You can use a mop pipe. Tape the pipe to the handle so that it points toward the floor. Then the door simply closes - and that’s it, it can no longer be opened. The pipe will simply hit the floor when you try to press the handle. This is one of possible options how to close front door keyless.

Aluminum can lock pick

To open the lock using this method, you will need an empty beer or cola can. It is easy to cut out and form a trefoil into a special shape, the middle tongue of which is used to open the lock. A Here another demonstration of this method.

Master key from paper clip and hairpin

This is the most famous and, one might say, classic method of picking a lock. We have seen many times in movies how an attacker takes out a paperclip and begins to diligently pick at the keyhole. This video shows how this is actually done. And here's another one option this method, which uses a pen cap clip and a hair clip.

Knife master key

The third video demonstrates a completely simple way to open small locks using a knife. Obviously, this method won't always work, but it's still worth a try. Especially when it comes to Chinese products used on bags and suitcases.
