How to open a metal entrance door lock without a key

If the key is lost or broken and there is no duplicate, opening the door lock may be the only way to get inside the room. There are two ways to resolve this situation: try to open the door yourself, or contact a commercial company that provides similar services. There is another option: invite a mechanic from the housing office, but in this case you cannot count on a quick result, since first you will have to fill out an application for a call, and then be patient and wait for the visit of the foreman, the only one for the quarter. Opening the lock yourself will not be easy, especially if we are talking about an entrance door that has two locks installed. Let's take a closer look at all the possible options.

How to open the lock on the front door yourself

If you need to open the lock on the front door yourself, you should call a specialized team of craftsmen who will carry out the entire operation without damaging the main mechanisms. To open a lock professionally, a specialized tool is required. If it is not possible to access such services, it is possible to use alternative methods:

If the door has a simple cylinder-type lock, you can try to find a key with a similar groove in the bit.

Simple cylinder lock

When breaking the door, a miniature file helps, with the help of which the unevenness of the internal contents of the larva is polished.
After the surface becomes smooth, a standard master key is used, which is used to open simple locks without secrets.
If it is possible to access the insides of the lock when removing decorative trims, you can open the mechanism with a screwdriver, and then turn the core in the bolt.

Opening a door with a screwdriver

If there is concentrated sulfuric or hydrochloric acid in free circulation, a chemical reaction can be started to dissolve the metal, which will cause the spring to weaken and the locking mechanism to spontaneously open.

It should be noted that there are also cardinal methods for opening a lock without a key - using a hammer drill, gas cutter or grinder, with the help of which the lock is drilled or sawed out along with part of the door leaf or frame.

Alternative opening options

Knowing the type of mechanism, along with the traditional method of opening the locking device with a special tool, you can try to open the door in other ways:

Selecting a key. This option is suitable for cylinder mechanisms; there may be problems with lever mechanisms.
By drilling out the secret part (pin), or knocking out the lever and opening it with a screwdriver.
By pressing the door. Press the latch with a screwdriver or knife until it comes out of the strike plate.
Removing the cover and opening it with a screwdriver.
By pouring acid or liquid nitrogen into the keyhole, then rolling up the folding mechanism.

Before you open the lock yourself, you need to be sure that you can do this work without breaking the locking device. Otherwise, it is better to contact specialists.

Main types of locks on entrance doors

Barn padlocks with lugs are a thing of the past. Today on sale you can find 3 basic types of locking mechanisms, each of which has design and functioning features:

Cylinder - a standard locking device consisting of a steel bolt and core, into which a cylinder cylinder with a unique arrangement of pins for the key is integrated. When the cylinder is turned, the eccentric ring acts on the tongue located in the body of the box, and the door opens.
Level - has a more complex design - the locking mechanism consists of many stacked plates - level, each of which has its own groove shape. The keys are equipped with a flat bit with similar mirror grooves. It is more difficult to counterfeit such elements, and it is almost impossible to pick the lock, especially when we are talking about high-quality mechanisms from world-famous brands.

Level castle

Crossbar - easy to install and operate. The principle of operation is similar to a cylinder product, with the only difference being that turning the cylinder does not activate the tongue, but the locking bolts, which go into the holes on the side of the threshold and the door lintel.

Deadbolt lock

Regardless of the design features, as well as the reliability class of the mechanism, a professional can open almost every lock with minimal damage to the door structure.

Help from specialists

You can open the lock with minimal losses by calling a locksmith from the nearest housing department. You can also contact a special company, whose employees will be able to come and fix your problem. Their services are quite expensive, but you will save on a new door and, most likely, will be able to keep the lock safe and sound. Now there are a large number of companies that are engaged in opening lock mechanisms.

Good to know

The services of private specialists will cost from 1000 to 3000 rubles, depending on the complexity of the lock being opened. You will also need to present documents that confirm your right to stay in the apartment, and an identity card.

Anyone can find themselves in an unpleasant situation and suddenly find themselves in front of the closed door of their own apartment. If the owner of his own home has lost the keys to his house, the question of what to do in this situation must be resolved in a calm state. First of all, don't panic. In this article, we have described all the available methods for opening common types of locks, which will help you solve the problem as quickly as possible.

How to open a cylinder lock

A cylinder lock with a low or medium level of burglary resistance can be opened using the simple technique presented below:

To open it, you will need a thin wire, which can be obtained by unbending a paper clip or hairpin.

Unbending a paper clip

To turn the lock, you need to prepare two identical pieces of wire.
One of the opening tools is bent at an angle of 90 degrees.
An L-shaped wire is placed in the upper part of the larva, after which the master gently presses on it, creating a slight counterclockwise force.
A straight piece of wire is inserted into the bottom of the lock to lift up any loose pins on the cylinder.

Wires in the castle

When both tools are in the right places, the top wire is carefully turned in the lock, which should give way and the door will open.
If the lock does not budge, before inserting the wire, you need to deform some of the pins using a standard flat-head screwdriver.
If the locksmith has never dealt with opening a lock before, the expected result may not be obtained the first time. In such a situation, the procedure is repeated until the L-shaped wire is installed exactly in the desired position.

Opening a lock with a wire

If your door has an expensive lock with complex, high-quality pins, the standard method of using a pocket pick may not work. In such cases, the technician should try to disassemble the lock. To do this, the decorative trim is removed to provide access to the screws, which are unscrewed sequentially. Next, the handle and rotary core are removed from the door. If the operation was successful, you can insert a screwdriver into the resulting hole and turn the lock.

Hacking levers and mechanisms with a tongue

Locks with a double-bit key are in great demand because they are considered reliable locking devices. But they can also be opened using a master key or improvised means. When opening such locks with a standard key, one bit raises the levers, and then the second moves the bolts. If you open the device with a master key, then the opposite is done: first the bolts are loaded, and then the levers are lifted with a hook

Lock with tongue

This work is painstaking, but success is guaranteed. You can open such a lock using a vandal method. To do this, you need to insert a suitable key or blank into the hole and, while striking, try to knock out the levers. It may not work at first, but the method is effective.

If you need to open a lock with a tongue, then in this case you will need a screwdriver or a thin plate. The tool at hand is inserted into the gap between the door and the frame. You need to press on the tool and try to move the tongue, then open the door.

How to open a lever lock

Lever locks have a complex design and are much more difficult to open than cylinder locks. The degree of protection of a mechanism is determined by its price, brand, number of levers and build quality. When performing an autopsy, professionals use a number of techniques, each of which requires skill and patience:

First of all, you can try to fit a similar key to the pins of the bit. To do this, a similar product with the same dimensions of the bit as the original key is inserted into the hole until it stops, after which the master strikes the free edge of the key with a hammer, like a regular chisel. If the lock does not have a high level of reliability, the pins will unbend, which will make it possible to turn the key and then open the door.

Pins in the keyhole

This technique may not work the first time, which requires cyclic repetition of the procedure until the expected result is achieved.

The second way to open a simpler lever lock is to make a master key from a small plate shaped like a key.

The product is made using metal shears from a sheet of galvanized steel, after which wavy ribs are applied to its surface by ordinary cold deformation.

Opening the lever lock using a plate

Such a homemade key will not work in all cases, but with a simple lock, it is enough to simply insert it into the hole and turn it.

If we are talking about an English lock with a spring tongue, it can be pressed out using a steel plate, a thin chisel or a flat-head screwdriver. Such manipulations are only possible with economy class doors, in which a gap is visible between the door frame and the leaf. The metal product is inserted into this gap, rests against the latch, and then, under the influence of friction, is gently pressed into the body of the lock.

When an expensive lever lock, consisting of a large number of plates made of high-alloy or hardened steel, is installed in the door, opening it using the above methods is impossible. In such situations, you should call a specialized service, whose qualified locksmith will perform the necessary manipulations using a professional tool.

Basic methods for opening lock mechanisms yourself

If you still don’t know what locking mechanism is built into the front door, then it’s worth trying to take the following actions, which are mainly used by intruders:

Try to find a similar key (if it is a cylinder lock);
Scrape off the pins a little and open with a pick;
Remove the overhead fittings and use a screwdriver;
Pour acid into the keyhole and wait until it corrodes the mechanism and the door opens;
Use a master key.

How to open a deadbolt lock

The deadbolt locking device is the simplest. Compared to locks of similar types that have cylinder or lever mechanisms. If the user has lost the key to such a lock, he can use the following available tools to open it:

A regular hand screwdriver with a flat tip. The tool is inserted into the gap between the leaf and the vertical post of the door frame, after which the bolt is pressed out.

Opening the tab with a screwdriver

If you have access to the door leaf on both sides, you can make an improvised master key using high-strength nylon fishing line or guitar string. In such situations, a loop is tied from the product, which is threaded into the cylinder core. As the string comes out from the reverse side of the canvas, it is wound onto the handle. By means of a circular movement counterclockwise in a tense position, the cylinder rotates, driving the bolt of the locking device.

Rotating the larva using fishing line

Wooden rod made of soft wood. The device is carefully driven into the hole so that it passes through all the spring pins. With the correct placement and the right choice of wood, the product will take the shape of a key, which will help turn the stick in the lock and open the door.

Opening a lock with a wooden stick

In addition to the methods listed above, you can also select a similar key for the deadbolt lock, since many products in the series are duplicated through a certain number of modifications.

If you contact lock picking professionals, they will offer to make a cast of the key and make a duplicate of the product, which can later be used to open the door without damaging the cylinder.

How to protect yourself from a key breaking in a keyhole?

Absolutely no one is immune from such a problem, but to try to avoid this trouble, it is worth listening to some tips on operating the locking mechanism.

Each locking mechanism has its own service life and after its expiration it is worth replacing. How to determine the degree of wear? This can be done by visual inspection. If the key and the lock itself are severely scratched, cracked, and the teeth on the key are scratched, then it is better to replace the locking mechanism as soon as possible.

There is an option to install a specially designed lock. It does not require a keyhole or key.

But if a situation arises with the lock breaking, then it is necessary to act in this situation as follows:

To avoid damage to the lock, if it breaks, you should call a locksmith who will help you open the front door carefully and without damage;
If the door urgently needs to be opened and there is no time to wait for a technician, then you can use the services of special companies that will quickly solve the problem. The cost of this service is quite high.

How to open an interior door lock

Most often, locks are on interior doors. Installed to conditionally restrict access to adjacent rooms. Such products can be opened with a simple shake if the locking device is equipped with a push-button lock on the inside.

Opening the interior door lock

When this technique does not work, it is permissible to use pins or wire from a paper clip, which will easily turn in the lock, repeating the algorithm described above for cylindrical locking devices of low security class.

When opening such doors, it is also permissible to press the latch tongue of the English lock using a thin metal plate, a screwdriver or a chisel. In such situations, it is necessary to carry out the procedure carefully to avoid accidental damage to the wooden door leaf.

Pressing the lock with a plate

Trunk Hacking

If the mortise lock of the car trunk is jammed, you can try to break it from the inside. This is possible with the car open. For hatchbacks and station wagons, it is enough to fold down the rear seats. And for sedan or coupe cars, you will need to completely remove the rear seat to get into the trunk. Here you can clearly see the special handle that opens the luggage compartment door from the inside.

If it is faulty or missing, you need to remove the door trim. Insert a screwdriver into the keyhole and turn it.

It is very difficult to open a mortise trunk lock without a key yourself, so it is better to contact a car service center.

What other ways can you open a door lock without a key?

If none of the methods proposed above work and the lock cannot be opened, you can resort to the following alternative methods of opening the mechanism:

When opening cylinder, deadbolt or interior English locks, you can try to find a key, since many products practically duplicate each other, and the pins themselves do not have high position accuracy.

Key selection

If you are unsuccessful in trying to open the door using non-destructive methods, you can drill out the lock cylinder using a simple drill and a metal drill bit. This method is not suitable for lever devices, and the master will have to use a high-strength screwdriver with a hammer to gradually knock the levers out of the structure.

Drilling out the larva

An old-style interior door or a standard wooden entrance door leaf can be crimped due to the gaps that form in the closed position. This gives the canvas a slight play, which can help during emergency opening.
Disassembling the locking device - removing the lining, unscrewing the screws, dismantling the handle, cylinder, and then turning the bolt using a screwdriver or steel rod.

Disassembling the lock

Freezing metal parts of the locking mechanism using liquid nitrogen. When the structure of the steel crystal lattice changes, it becomes brittle, which causes immediate destruction upon impact.

Freezing a castle with liquid nitrogen

The last radical method is to pour concentrated acid into the body of the lock cylinder, which promotes an instant chemical reaction - the metal reacts with the acidic residue, forming a salt. If you wait for a long time, the larva will be completely destroyed, and the master will have access to the bolt of the locking device.

Filling the castle with acid

All descriptions of the algorithms can be easily done with your own hands, without the need to use special tools and materials. Thus, property owners should not turn to professionals for an expensive service until they themselves have tried several simple methods for opening a lock without a key.

Opening locks of different shapes

Rack type locks are used in premises for various purposes, but how can you open the front door without a key? To do this, it is recommended to arm yourself with a knitting needle or a thin screwdriver. Insert the master key into the keyhole and try to carefully move the bar in the direction of opening. It is important to hold the rack bar at this moment so that the crossbars do not snap back under the action of the spring.
Locking mechanisms for a cross-shaped key of hinged and mortise design are opened with a special collet-type tool. The design of such locks has 3 groups of pins, and the tool has the same number of hooks. It is placed in the keyhole and passed over the pins several times. After this, the lock should turn. A Phillips screwdriver can also help out in this case. Simply insert it into the hole and turn it clockwise with force. To handle the mechanism, a small hole is drilled above the key hole. The master key is inserted through it, the stopper is lifted and the bolt is pushed back.
Devices with a latch are opened with a thin and durable tool that matches the shape of the well. For round holes, an awl, knitting needle or paper clip is suitable, and for elongated holes, a knife, screwdriver, nail file or scissors. It is placed in the gap and, when pressed, they try to turn the door handle.

How to open a lock with a broken key

If the key in the lock breaks due to careless rotation, it is possible to use several alternative methods for opening the door, depending on the nature of the damage to the metal product:

If a piece of the key looks out of the hole by at least 1 millimeter, it can be picked up with pliers, tweezers or another rigid grip. If the key gives in, you need to pull it out and make a duplicate, after which the lock can be opened freely.

Broken key in the well

When it is impossible to get the fragment out, it should be taken into account that the beard, which remains in the body of the larva, has already pressed out the necessary pins, and to open the lock, only a lever that creates torque is required. In such cases, you can use a rigid steel plate, which is inserted into the well until it stops. After this, the key should be turned at maximum tension.

Removing a broken key from a well

If both methods do not work and the key has blocked the cylinder, it will have to be drilled out with a high-quality metal drill. It is also possible to knock out the cylinder using a chisel and a hammer, but this method can cause damage to the remaining parts of the locking mechanism, and it will have to be replaced for further use of the door leaf.

What to do if the key is broken?

How can you open a metal front door without a key if it suddenly breaks and part of it remains in the lock?

The main rule is to never try to remove a piece of debris from the locking mechanism with your hands, without tools, because you can push it even further and then you won’t be able to get it out with anything. Because of this, you will have to completely change the entire mechanism.

For this task, you should arm yourself with a nail file, wire cutters, pliers, and a screwdriver. Of course, you may not need everything, but something will help. If the key breaks while opening the door from the outside, then you should run around your neighbors in search of the necessary tool.

Using pliers, you should try to carefully grab the edge of the broken part and pull it out. But if the key is broken so that there is nothing to grab onto, then you can try to pull the fragment a little with a jigsaw file and then grab it with pliers or wire cutters.

In this case, you need to act as carefully and slowly as possible, so as not to push the fragment even deeper.

How to open a door from the inside when jammed

If the English door lock mechanism is jammed, this indicates wear on the spring mechanism. In such cases, turning the key or master key will not help, since the tongue will not give in even with a working cylinder. When such a situation occurs, you need to perform the following simple algorithm:

The lock mechanism must be treated with a penetrating lubricant so that the tongue can slide along the metal surface without friction.

Lubricating the lock with a penetrating compound

A long screwdriver with a flat tip is inserted into the gap between the door frame pillar and the leaf.
Another screwdriver of the same configuration is inserted 2–3 cm below.
One of the tools is used to fix the tongue in a static position, the other is used to set it in motion through translational movements of the lever.

Opening the door with 2 screwdrivers

As the tongue slides a few millimeters using one screwdriver, the master constantly fixes its position with a second tool.
When the tongue is almost free, one of the screwdrivers catches its edge, and the door opens.

To avoid a recurrence of this situation, you should replace the lock or carry out repair work. To do this, the product is removed, disassembled, and the spring is put in place. If the mechanism has become unusable, it should be replaced. Typically, springs for standard locks are sold at hardware stores.

Practical recommendations for preventing the locking mechanism

In order not to periodically waste time and think about what to do if the front door lock is jammed, do regular maintenance of the mechanism. When to lubricate the lock? - characteristic sounds - grinding, rustling when turning the key; — jamming in the cylinder when trying to insert or remove the key; - Difficulty turning.
Special pads help prevent contamination of the keyhole. This is primarily necessary for street doors installed at the entrance to the building.
The locking mechanism has a complex design, which comes with an original key. Practice confirms that if such a lock breaks, it is much easier to replace its cylinder (for a cylinder model) or the core of a lever lock (with subsequent recoding). Even an experienced master will not make a one-to-one duplicate of such a key, having only a sample of it. The result is increased wear of the material and clogging of the mechanism with metal dust. After some time, you are faced with the fact that the key in the lock does not turn.

Rough methods for opening a lock

If standard methods that do not involve destroying the locking mechanism do not help, the technician, with the consent of the apartment owner, will have to use crude methods to correct the current situation:

Knocking out the cylinder core using a chisel and hammer. In such cases, damage is possible not only to the cylinder, but also to the crossbar, since the parts are mated to each other with a steel rotating ring with a protrusion.

Knocking out the larva with a hammer and chisel

Drilling out the larva. A metal drill is fixed to the electric drill, after which its tip is inserted into the hole for the key. As the drill operates, the metal is gradually drilled out, leaving chips and opening access to the locking element. After the physical destruction of the larva in the cylinder, the tongue is moved back by simply pressing the hand.
Cutting out part of the canvas along with the lock.

Cutting out a lock and a piece of canvas

Cutting a supporting steel frame by sawing the post.
Cutting off hinges, provided there are no anti-removal pins on the door.

Cutting hinges on a door

The methods described above are used only in extreme cases, especially if we are talking about an expensive product. If non-destructive methods do not help, you should consult or ask for the help of a specialist before using brute force. The cost of calling a professional will be much cheaper than purchasing and installing a new entrance or interior door.

Warnings

If you open the lock correctly, it will not be damaged, but if the cylinder tension is too strong or too much pressure is applied to the pins, there is a risk of damage to the lock mechanism.
If the pin doesn't budge when you press down on it with a pick, you may be over-tensioning the cylinder and causing the holes in it and the body to move apart. Try loosening the cylinder tension. There is a risk that the replaced pins will fall into the cylinder. Unfortunately there is no other way out. Try changing the order of the pins you are working with the next time you try.
There are many different laws regarding picking locks, owning master keys, and using improvised tools. In Russia, master keys (devices that allow you to open a lock without physically destroying it) are regarded as technical means intended for secretly obtaining information, the production, acquisition and sale of which is subject to licensing. Illegal trafficking (i.e. manufacturing, purchasing or selling without a license) of such products is a criminal offense punishable by up to 4 years in prison. Well, besides this, it’s not worth mentioning that only pick your own locks!

Useful expert advice

Door repair and maintenance experts often share simple tips with the public on how to avoid serious structural damage followed by costly repairs:

If you always take with you a simple universal master key for any type of lock, one day it can come in very handy. You can purchase such a tool at any construction or household retail outlet for nominal money.

The simplest master key for a lock

In each apartment building there is a management company that is responsible for the maintenance of public premises and provides all possible household assistance to residents in the event of emergencies.

In such organizations, most often, during the daytime, there is a master, locksmith or plumber who can be contacted for the service of opening the door without a key. Such specialists have the necessary set of tools and skills to act promptly in such situations.

Professional door opening

For people who are prone to forgetfulness, experts recommend installing smartlocks. Such locks can be easily opened by scanning a fingerprint, typing a code, or reading the retina. Such devices do not require keys, and all maintenance and care of the equipment consists of timely replacement of batteries.

Smartlock with code access

By following these simple recommendations, the apartment owner can save money and time. Even if an emergency situation has not occurred for many years, no one is immune from its sudden occurrence.

If a person is outside

An unpleasant situation - you opened the door, stepped out of the threshold, tied your shoelaces and heard a telltale click behind your back. At the same time, you realize that the keys were left on the nightstand near the door. Such a problem is only possible if the latch is connected to the lock. When it is closed, the bolt extends half a turn and that’s it, you can’t get into the apartment or house.

The same can happen if the lock for some reason stopped working correctly and, after turning half a turn, blocked the key.

Where to call in such a situation:

Go to the housing office and call a locksmith. The service is available from approximately 8 am to 5 pm, and even then it is not a fact that the employee will be sane. But it's still worth a try.
Neighbors - ask them for help, go into their apartment, go out onto the balcony, climb onto yours and open the latch from the inside. In the case of a faulty lock, this will not help.
Industrial climbers , if the apartment is located high, pay them a round sum upon completion of the work. You should not contact this specialist if the reason is a broken lock.
At the Ministry of Emergency Situations. True, the emergency service does not like to go out on such trivial matters, although they open the doors very quickly. And what to do next is already a headache for the owner.
For the master from the lock opening service - a universal option, both with a latch and with a broken locking mechanism.
To a specialist from the company that installed the door. This method is only suitable for modern products whose manufacturer has not sunk into oblivion.

The methods described above involve maintaining the integrity of the door leaf (with the exception of calling the Ministry of Emergency Situations).

How to open it yourself:

If the structure is without a rebate, you can use a thin screwdriver to try to push the bolt into place, and in the case of a broken lock, saw through it with a grinder.
Squeeze it out with a crowbar. This will work with almost any apartment door, with the exception of armored or additionally reinforced with an armored envelope. But in this case, the door block will have to be changed.

The arriving specialist may ask the victim for a document that would certify that he lives at the specified address. However, in 98% of cases, such questions are not asked at the initial stage. Opening the door is legal without documents. But after solving the problem, it will not be superfluous to show the master your passport, payment receipt or lease agreement.

Briefly about the main thing

Losing the key to the front door is an unpleasant situation that requires certain skills to be able to enter the apartment. The simplest door lock can be easily opened using a standard master key, a wire from a paper clip or hairpin, or using a metal plate simulating a key. If this technique does not help and the cylinder does not turn, you should use a screwdriver to mechanically press out the tongue blocking the door.

If the cylinder is completely blocked, it is permissible to resort to rough mechanical intervention by drilling, knocking out or cutting out the lock. After such procedures, as a rule, an expensive restoration or replacement of the door is required.

Latch

The simplest mechanism, consisting of only two elements - the body and the tongue. Serves to prevent the door from spontaneously swinging open. It has a budget price. In addition to its affordable price, the device attracts:

long service life;
ease of recovery;
reliability of the design;
no need for a key;
very rare breakdowns.

In this case, different types of latches can be used - latches, roller, magnetic, sliding or with a lock. The first type of locking mechanism is equipped with a tongue that is beveled on one or both sides. In the second case, the tongue is presented in the form of a rotating roller.

Magnetic ones hold the door using the system of the same name. And for sliding ones, the latch acts as a bolt. To open or close it, you need to pull the lever or rotate it around its axis. Locking mechanisms with a latch are similar to locks. The latch blocks the rotating or pressing mechanism.

Important ! If latches of this type are handled incorrectly, the latch may fail and the tongue may jam.

Measures to prevent such a situation

Situations where the lock breaks can be avoided. If not guaranteed and 100%, then certainly minimized.

Yes, there are a number of other points that can be taken into account when installing a door lock in order to facilitate its dismantling:

Install locks with emergency opening capabilities.
Avoid using complex mechanisms unless absolutely necessary.
A spare set of keys can be placed in a drawer in the kitchen or hallway.
Regular lubrication of moving parts (it is better to use a penetrating lubricant).
Timely replacement of locks that have begun to jam.
Leave a gap between the door leaf and the frame as a last resort - in case you still have to cut off the bolts or latch tongue.

These simple methods will help you avoid an unpleasant situation with a slammed door, a broken lock, or will be useful in solving the problem that has arisen.

Not only can the interior door be closed, but sometimes you just can’t deal with a blocked washing machine door. Read our next article on how to open a washing machine.

Complex systems

To dismantle the cylinder mechanism, you need to unscrew the end plate, then remove the front part. Next, you need to push the lock with a screwdriver so that you can subsequently grab it with your hands and carefully pull it out.

Removing the lever mechanism is much easier. It will be enough to unscrew the plate, move the internal device to the edge, and carefully remove it.
