How to open a door without a key if the door has slammed or the key is lost

Usually, the owners of apartments or country houses have several sets of keys to the front doors. However, people take only one set with them to work, to the store or when traveling to other places. Therefore, in a situation where the keys are lost, there is a problem of access to the premises. It will be possible to correct the unpleasant situation and get to the object if you open the door lock. The same operation will have to be performed when the doors are slammed and the keys remain at home.

For help, you can contact the management company. The locksmith of the organization is able to pick the lock, but he does not have the necessary professional skills. Therefore, there is a high probability of damage to the door structure.

The best option to open the front door lock without a key and not damage the canvas with the box is to contact the emergency service. An employee of a specialized organization has knowledge, experience, and the necessary tools. Therefore, it will be possible to quickly open the door without a key with minimal subsequent costs.

Opening the front door lock by a specialist

However, the master will need to prove that this is your house or apartment and you live here. Usually a passport is presented for this. In the absence of a document, a police officer is invited.

If it is not possible to call a specialist, you must use the recommendations of professionals regarding the opening of the entrance and interior door structures. Tips will help you understand how to open the door of the house without a key yourself.

Ways to open the lock without a key on the front door

It is quite possible to open the lock without a key on your own on a metal front door, if you know the design and principle of the locking mechanism. The process depends on the type of mechanism and becomes more complicated when a branded lock is installed in the door structure. Moreover, entrance metal doors are usually equipped with at least two locks and may have additional security equipment.

You need to know how to open the lock if the key is lost and when it breaks in the mechanism. In the second case, opening the locking device begins after removing the debris. This process is carried out as follows:

• Lubricate the lock with machine oil or another suitable compound (there are sprays) by dropping it several times into the keyhole.
• It takes some time until the substance spreads evenly inside the keyhole.
• The rest of the key is pulled out with pliers. It can also be removed by hand when a piece of sufficient length sticks out of the lock. If it was possible to pick up the broken part of the key, it swings and at the same time is pulled towards itself.
  

  If there is an opportunity to grab it, we turn the key fragment with pliers

• When the piece cannot be caught, two thin metal rods are inserted into the keyhole next to the remainder of the key. You can work with knitting needles. The inserted "tool" must be pressed and pulled towards you.

After removing the debris, it is recommended to take it to the workshop. The master will be able to make a duplicate of the key, and in this case the issue of opening the door lock will be resolved.

How to quickly open a cylinder lock without a key

Cylindrical locking mechanisms are installed on modern entrance door structures, because they are more reliable locking devices. To open such a lock, you need to know its design.

The stationary central element of the lock is made in the form of a cylinder. In addition to the pins (pins), inside the locking mechanism there is still a plug, a block with springs and a separate spring.

Cylinder lock device

The pins are placed at different depths. Some of these prevent the cylinder from spinning freely. There are indentations on the key of the cylinder lock. It is they who allow the pins to take the position in which the cylinder of the locking mechanism turns. This triggers the latch, and the deadbolt takes up such a place that the lock opens.

The number of indentations on the key blade body is equal to the number of pins in the lock. With their increase, the process of breaking the lock mechanism becomes more complicated. Despite the difficulty of the process, opening cylindrical locks is feasible by one of the following methods.

The first way

The cylindrical locking mechanism can be opened using the impact method. This is a universal way. It's called bumping. After a forceful impact (impact), the pins jump out of the cylinder.

By hitting the key for a split second, the pins are aligned and it is possible to turn the larva

Second way

Using a thick plate with a sharp end, it will be possible to open a cylinder-type door lock. To implement this method, it is necessary to insert the "tool" into the well and apply strong pressure on the locking mechanism. The sharp end of the plate will shear off the protruding pins that prevent the cylinder from moving.

Third way

An electric drill can also be used to open the front door lock. Shafts with springs are drilled with a power tool. This will allow the cylinder to rotate unhindered.

Having drilled the locking pins, you can turn the cylinder with a screwdriver

When the lock has reinforced protection in the design, it will not work to use an electric drill with a drill for metal. In such a situation, the best option would be to seek help from a specialist in a specialized company.

How to quickly open a keyless lever lock yourself

Lever mechanisms are also reliable locking devices. They are often installed on entrance door structures. Therefore, when property owners lose their keys, they often want to open the lever lock of an iron door using available means.

To open the mechanism, you need to know the design of the constipation. Lever lock works due to the presence of a set of plates. Each such element has a specific shape and acts on the crossbars. The mechanism also has a main pin. It is attached to the central levers. The pin moves along the slots of the other plates, building the required combination of levers. When the key is turned, the plates move in a specific sequence. It is this action that closes and opens the door.

The number of plates affects the difficulty of opening a lever lock. Such locking mechanisms are highly resistant to mechanical stress. For this reason, physical force is not recommended. The best option is to open the lock using more efficient methods.

The first way

The lever locking mechanism is opened using metal lock picks and a gradual selection of the code:

• to create tension in the lock, it is necessary to abut the master key inserted into the key hole against the main plate;
• the position of the other levers is alternately changed with the help of the second master key until the required combination is found.

After a successful selection of the desired position of the plates, the main pin in the lock will begin to move. As a result, the door structure will open.This method is difficult to implement without experience. Moreover, it takes a long time to complete it.

Opening the lever lock

Second way

If you remove the main pin, you can also open the lever lock. This operation will allow the main plate to move freely. The method is quite complicated, since the device is located behind the door body and you need to know exactly where to drill.

We open the rack and pinion lock without a key

Locking mechanisms of this type are distinguished by excellent strength. Therefore, it is not advisable to open the rack and pinion locks using blows. Better to use more humane methods that will not harm the structure. To implement them, you need to know the structure of a rack and pinion lock:

• galvanized body;
• metal locking crossbars with cut grooves;
• spring elements for pushing out the crossbars while closing the locking mechanism;
• a key in the form of a metal flat bar or with a section in the form of a rectangle.

Thanks to the simple design of the rack and pinion locking mechanism, gentle opening methods are easy to implement.

Rack lock device

The first way

This method is carried out using two flat screwdrivers of small thickness. The tool must be placed in the keyhole at the same time. The lock is opened in the following sequence:

• the first screwdriver is inserted into the keyhole and installed on the notches of the rail, which allows it to be moved to the side;
• the second screwdriver is inserted inside the lock also through the key hole so that the rail does not change its position after the shift.

Further, it is necessary to repeat steps 1 and 2 until the constipation opens. If necessary, you can drill a larger key hole.

Second way

This method can be implemented if there is a gap between the canvas and the box. Insert a crowbar into the gap and maximize the gap. When the actions are successful, a flathead screwdriver is taken. With its help, the crossbars are pushed into the lock through an increased gap.

How to open a padlock quickly

Opening the padlock mechanism without a key is quite simple because such models are not very durable. They are often used in outbuildings to restrict access to utility or basements.

As with other mechanisms, to open a keyless padlock yourself, you need to know its design. However, there are several types of barn-type constipation:

• Open mechanism, in which the darling has a curved shape.
• Closed device with locking part completely hidden in the housing.
• Semi-closed lock with a pin instead of a darling. The locking element is partially hidden in the housing.
• A mushroom-shaped hinged lock, which has a pin instead of a darling, almost completely hidden inside the case.

To open a padlock, you also need to know the type of locking mechanism inside the product. The basis of this part of the locking device can be a cylinder, screw, levers, discs. There are also models of padlocks that can be locked by setting a code. The type of internal mechanism determines the method for opening the padlock without a key.

1 way

An open locking mechanism with a protruding scent is broken open with an ordinary crowbar. You can also use a hacksaw for metal. This tool will be able to cut the darling.

A simple enough way to just break the lock if there is no crowbar

With two wrenches, the lock can be broken. To do this, you need to attach a tool to each darling. In this case, the keys must touch each other with their outer edges. The next step is to try to connect the free parts of the tool with force. After this action, the mechanism should crack in the area of ​​the latch.

2 way

This option is realized using a cut out small piece from a tin can. It is pre-folded from one edge.Then the straight side of the sheet is inserted into the gap between the locking element and the body. Then the plate is pushed into the lock and rotated. As a result of these actions, the locking mechanism is retracted to the side.

Opening the lock with a plate

How to open an interior interior lock without a key

If it is impossible to open the interior door, many property owners see the only way out - to remove the structure from the hinges. You can perform this procedure when you are inside the room. The operation is carried out by removing the decorative plug and removing the pin from the fittings. After that, the door leaf can be easily removed from the box.

Interior doors are equipped with simple locking mechanisms. Therefore, solving the problem of how to open a slammed interior door can be easily and quickly. This is especially important when a small child is blocked in the room.

The latch closed from the inside

Interior doors are usually fitted with locks with a key located on the inside of the structure. It is she who can snap into place if you sharply pull the handle during closing.

When this situation has occurred and the door has slammed, it is necessary to find a small hole on the lock from the outside. Then you need to insert a thin metal object into it. In most cases, a knitting needle is used for this. The action will push the button outward, which will lead to the opening of the door leaf.

Options for opening an interior door with a lock

If there is a locking device with a key in the interior door, the burglary process becomes more complicated. To open the lock, you must first pull the handle. Due to this action, the deadbolt can rebound if the locking mechanism is in a loose state. Otherwise, you need to use a small metal object that will fit into the keyhole. This tool needs to be rotated slowly in order for the pins to move.

The method of opening the door depends on how the door is installed. Here are a few:

• disassemble the hinges or even cut them;
  

  Door hinges can be disassembled

• squeeze the door from the jamb;
• slide the latch with something flat (tin, bank card),
• try other keys, as the quality of the locks is not high, it may work

Conclusion

If you lose your keys or in a situation with a slammed door, there is no need to panic. Manufacturers have not yet come up with mechanisms that cannot be opened. Therefore, it is necessary to adequately assess the situation and carry out the correct further actions.

It is recommended to make several duplicate keys in order to avoid opening the locking mechanisms and calling a master from a specialized company. They need to be deposited with relatives or good friends.
