Door locks provide security and peace of mind, but can also be serious irritants when they fail. Even worse, if you forget the key on the other side of the door. Remember, before proceeding with fraud with breaking the lock or doors, you must make sure that there are no other options. In addition, most of the methods we have proposed also require time to master them, so keep that in mind.

Opening interior doors

The least problem is opening the interior door, since simple locks are often installed in such structures. Such designs are equipped with a latch on the one hand and a keyhole on the other. This problem is often encountered by parents of curious babies. A child can easily slam a door and turn a knob, but the reverse process may cause difficulties for him. Then parents immediately face two tasks: how to open the lock, and how to keep the door intact. Here's what to do in this situation:

  • inspect the structure of the castle, the shape of the well,
  • pick up a tool that can be inserted inside the well,
  • carefully open the door, being careful not to damage the door leaf and the lock.

The choice of tool depends on the shape of the keyhole. If it is round, then a thin solid object is required: an awl, an unfolded paper clip, a knitting needle or a toothpick. For a well with an elongated shape, you need something flat: a screwdriver, a nail file, scissors or a knife. To open the door lock, you must insert the tool into the well. While pressing on it, turn the doorknob. The main thing is not to overdo it so that the tool does not break and does not get stuck in the well.

There is another way to open a slammed door. To do this, a flat object is inserted between the end of the door and the box, which slightly push the latch towards the lock. It is enough to shift it by only a few millimeters.

If the lock has a borehole on each side, and an inserted key remains in one of them, it will not be difficult to deal with the problem if the design does not provide a threshold. Under the door you need to stick the spread out newspaper as far as possible. Then with a sharp object we push out the key from the well, which should fall on the newspaper. We take it out and open the door.

Opening the front door

A more difficult task is to open the entrance doors, since they usually have at least two locks. It is worth thinking carefully before trying to independently solve a similar problem: an unprofessional approach can adversely affect the condition of the door itself, and replacing the metal entrance structure is not cheap. Getting started, do not forget that the main goal is to open the locked locks, and not to break the door.

The process of this event will depend mainly on the type of castle. If the reason for opening the door is a broken key, you must first remove the chip from the larva. To do this, first pour a few drops of lubricant into the keyhole: WD-40 or machine oil. It will take 15–20 minutes for it to spread evenly throughout the well, after which the chip can be removed. If an insignificant part of the chip protrudes outward, this simplifies the task. It should be gently hooked with pliers or tweezers and, swinging from side to side, pull out. If the chip cannot be caught outside, two thin objects, for example, an awl, will be required. With the points we capture the stuck part, swing it and try to move it from its place. When the chip is removed, you will very soon open the door to the apartment: a good master will make a duplicate of two broken halves, and this will solve the problem.

Now we’ll look at ways to open the door without a key if the key has been lost and there is no way to make a duplicate.

Options for opening a cylinder lock

If you set the task to open the cylinder lock and keep it at the same time in working condition, then you need to possess the virtuoso abilities of the cracker. Such devices have a high level of secrecy, but it will not be difficult for an experienced craftsman to open the cylinder lock with a hairpin or a regular paper clip, although it would be more convenient to use master keys. Consider an emergency: how to open a door lock with a paper clip. We will use it as a master key, but we will still need a “collar” that will serve as a screwdriver. The task is to straighten the paper clip, slightly bend the edge with a hook and insert into the larva. Now you have to focus on hearing. Our task: to put the pins of the secret mechanism in the correct position. They must be lifted in turn, using an impromptu master key and convolute. As already noted, this is a very difficult task, which is almost impossible to cope with without proper skills.

There is a less delicate but more affordable way. hack door lock. It will require tools: an electric drill with a drill designed for metal, a flat screwdriver and a hammer. Sometimes the lock can be cracked without drilling, so you should first try this option:

  • insert a flat screwdriver into the larva as deep as possible,
  • with considerable effort, try to turn a screwdriver inside the lock,
  • upon successful attempt to pull out a screwdriver, with which the secret should be removed.

The task is completed - the door can be opened. If this method is unsuccessful, you will have to take a drill. We direct the drill directly into the larva and drill until we pass the whole secret to the end. After that we pull out the larva and open the door.

It is important!The method of drilling or knocking out a cylinder lock is completely powerless if the device is protected against breaking.

Methods for opening a level lock

You can break the lever mechanism or try to open it in a delicate way.

To break the lock, you must remove the main pin of the structure, which is responsible for moving the levers. To do this, you need a drill with a drill for metal, a hook or a bent strong wire, a paper clip. But even with a tool, this task will not be easy, because you need to drill strictly in the place where the reference point of the secret mechanism is located. When it is drilled, you need to insert a bent hook into the hole and turn it. In this case, all the levers freely move, and the door can be opened. As in the case with cylinder mechanisms, this method is completely ineffective for locks that have protection against breaking.

Now we will consider how to open a door lock with a level lock, using master keys or objects that can replace them: paper clips, hair clips, pins. The opening of door locks is carried out with two master keys. The first is inserted into the keyhole until it stops in the main board. The second one is to alternately select the desired position of the levers so that the main pin moves. You should be prepared for the fact that this process can take a lot of time and end in complete failure if you have never opened locks before. Therefore, it is advisable to invite experts.

How to open a castle

If there is a rack and pinion mechanism installed on the entrance structure, it will not be very difficult to open the door lock without a key. Since the lock is well protected from rough impact, we will not consider options for how to crack the front door. Having the usual tool at hand, we can gently open the mechanism in one of three ways.

  1. Take two flat head screwdrivers. They must be thin in order to freely enter the well at the same time. First, we put one screwdriver into the well. We need to put it on the notch of the crossbar and move it to the side. Then we insert the second screwdriver and with it we fix the position of the crossbar. Repeat these steps until the lock is open.
  2. We can open the door locks of the front door using a wooden wedge key. For its manufacture, we need wooden wedges made of soft wood. In size, it must correspond to the parameters of the well. The wedge must be driven into the well, then pulled out. Notches will be visible on the surface of the wood. We'll have to cut the wood a bit to make it look like a key and open the door.
  3. This option is available only if there is a distance between the door leaf and the duct in which the crowbar can be inserted. The tool is placed in the gap between the jamb and the door, then squeeze it all the way. We have a gap where you can insert a flat screwdriver and slide the bolts inside the lock.

Opening the padlock

Padlocks are not very durable, but often enough they are used to protect utility rooms, sheds, cellars. With the loss of keys, such locks are usually hacked because they are not of great value. Here's how to break padlocks:

  1. Take two open-end wrenches and insert them so that each of them captures one handle of the castle. At the same time, the keys must touch the side ribs. The free edges of the keys must be pulled together. As a result, a part of the lock breaks near the latch.
  2. We cut a small plate out of a can, bend one edge. With the bent side, we insert the workpiece into the slot that separates the lock case and the opening handle. Use a screwdriver to push the plate deeper. As a result, the latch opens.
  3. For the third option, we need a self-tapping screw and a nail clipper. We screw the self-tapping screw into the lock cylinder, then we hook it with a nail clipper and pull out the cylinder.


The loss of keys is not a reason to panic, but it is not the most suitable case to urgently master the skills of a locksmith. Opening doors without a key, even if you have the right tool at hand, is no easy task. Inadequate handling of the lock can only aggravate the situation. If you are not confident in your abilities, it would be advisable to contact a specialized company whose specialists have all the necessary equipment and know exactly how to open the front door without a key so as not to spoil the door and lock.


First try to open with a similar key. Did not work out? In principle, we did not really hope. It’s just that sometimes completely worn-out wells lend themselves to a persistent key (this is also true as a metaphor). Now borrow a screwdriver, a hammer and pliers from your neighbors. After removing the decorative trim around the lock, catch the protruding cylinder with pliers and swing it until it breaks. Knock out the rest, insert a screwdriver inside and, prying the mechanism, open the lock. Another way: drill a hole below the keyhole with a 5 mm drill, then insert a screwdriver instead of a key and turn it to the side - the lock will open. By the way, if you got a taste, order special master keys for cylinder locks - electric pick and pickgun (cost from 2 to 7 thousand rubles).

Identify the device model and type in Google “doorphone codes”. And it’s better to get a universal key for intercoms (five hundred rubles on the black market) and become the sovereign of the porches!

Sometimes it is easier and faster to knock a door if it opens inward. Beat in the place near the lock (closer to the center of the door), concentrating the force in the heel. The foot of a fixed leg during a strike is directed parallel to the door. Only cops in TV shows knock the door off the shoulder, and save a shot in the jump for those outside the door.
