What to do if the key in the car lock is broken and how to get it out

A key breaking in the core of a lock is an extremely unpleasant occurrence, especially if you want to keep the lock, and you also have spare keys. A stuck key fragment not only prevents you from opening the lock, but can also render it completely unusable.

Fortunately, there are ways to deal with this problem using available means. We bring to your attention ten ways to remove a broken key from the core of a lock.

Types and characteristics of locks

The following types of locks are distinguished:

1. By type of fastening:

• Mounted. These are locks, the fastening of which is carried out by threading the bow into the eyes. Padlocks are easy to install and replace. However, they have rather low burglary resistance. Scope of application: sheds, warehouses, basements, garages.
• Mortise. These are the most commonly used locks, installed directly inside the door leaf. It is advisable to embed them into metal doors, where they are protected from drilling by a sheet of metal. The locking mechanism must have high resistance to tampering, secrecy, reliability and durability.
• Invoices. Installed on the surface of the door leaf. Can be used for wooden and metal structures. They are characterized by ease of installation, repair and replacement, but they are not sufficiently resistant to hacking attempts.

2. By type of locking mechanism:

• Crossbars (rack and pinion). Inside them there is a crossbar with teeth and machined grooves. These locks have low burglary resistance, so their use to protect valuable items is not recommended.
• Level ones. This is the most reliable type of lock with a secret part in the form of plates (levers). The larger the lever, the more reliable the lock (preferably 6-8). Often, lever locks can be combined with other security systems.
• Cylinder. The design of the lock includes a mechanism consisting of a cylinder, a cylinder and a lever mechanism. Cylinder locks are characterized by high reliability. They are single- or double-sided, single- or double-row.
• Code ones. Used to protect gates, access doors and interior spaces. They do not require a key, but due to their low security level their use is limited.
• Electromechanical. They are similar in design to traditional mechanical locks, but can be opened and closed remotely. They can be mortise or overhead.

Tools for the procedure for obtaining a piece of the key

In order to get a broken key out of a door lock, you will need some tools that you can borrow from a neighbor, if this is not a private house with a garage.

1. Thin screwdriver - regular and figured;
2. An awl is a tool for stitching shoes and other items;
3. A jigsaw is a small saw;
4. Hairpin for pinning hair;
5. A nail puller is a hand tool;
6. Pliers and hammer;

   Necessary tools to remove the key

7. Medical tweezers;
8. Drill, possibly using a grinder.

Methods for removing a broken key from a lock

Methods for extracting key fragments are divided into three main types:

• Gentle, during which the metal fragment is removed without damaging the lock mechanism;
• Damaging. The main task of this method is to disassemble the lock. In most cases, after disassembling the lock, the cylinder with a jammed or broken key is replaced, after which the mechanism is assembled and installed in the door without any problems. But there are some locks that either cannot be reassembled or cannot be disassembled. In this case, you will have to install a new mechanism;
• Breaking. They are used in situations where it is impossible to disassemble the lock without damaging the door leaf. Therefore, after breaking it out, it is necessary to change not only the locking mechanism, but also the fittings, and also, in some cases, the entire door.

Gentle methods

You should always start with gentle methods. In this case, the fragment is removed without damaging the locking mechanism. Thus, the lock remains intact, and you can subsequently use it for its intended purpose.

Before proceeding with removal, apply some lubricant into the keyhole. Machine or gun oil, WD-40, brake fluid, and even any vegetable oil are suitable for these purposes. Using a syringe or other available tools, carefully place a few drops of oil into the lock. The liquid will wash the core from dust and improve the sliding of the fragment.

How to extract the key?

• If a piece of the key sticks out of the hole, you are lucky. This is the simplest of all possible options. Take tweezers, small pliers or pliers and try to grab the protruding piece with them. Squeeze the broken piece tightly and try to remove it by gently vibrating and moving the broken key from side to side. At the same time, try tapping the lock a little - the vibration will help move the stuck piece out.

• If the door is open, try to “knock” the piece out of the keyhole. To do this, tap the lock on the opposite side with a hammer. The vibration will help the broken piece come out. This method is perfect for a padlock. How to do it correctly, watch the video.

• Try inserting two thin awls into the gap between the keyhole and the key. This is done from opposite sides: from both sides or from above and below. Grab a piece of the key with an awl and, using light, rocking and vibrating movements, try to remove it.

• Take a thin jigsaw file and insert it into the lock with the notches facing up. Rotate the saw to catch the chip. Then smoothly and carefully pull out the file along with the stuck piece.

• If you broke your key after returning from fishing and you have gear with you, a fishing hook will come to your aid. Unbend it, insert it into the lock so that the notched tip catches the fragment and pull it towards you. This method is quite labor-intensive and requires patience, but in half the cases it is successful.

• The last method is within the capabilities of a real “jeweler”. You need to drill a hole in the end of the stuck piece and screw a self-tapping screw into it, without damaging the keyhole. Then, holding the screw head, pull the broken piece out of the lock.

All actions must be performed without haste and carefully. In this case, you have a chance to get the key and not make the situation worse. If gentle methods do not help, you need to use heavy artillery.

Removing the lock by removing the cylinder

It happens that gentle methods do not help and you have to completely remove the larva. There are proven “barbaric methods”, after which a complete replacement of the door lock is necessary:

1. knocking out the cylinder. There is an armor plate on the back of the door. It needs to be removed along with the screws and hit with a hammer on the protruding part of the cylinder;
2. prying the core. It is pryed off with an awl, a thin screwdriver or a hairpin. Using any tool, you need to lift the pins in the secret mechanism and release the rest of the key;
3. drilling out the cylinder. It is drilled over the keyhole, turned and removed;
4. removing the lock from the end. The method is used with the door open, when the key fragment does not protrude from the hole. The lock is removed and taken apart.

Using extreme measures

When the key in the door lock breaks and other methods do not help, the owner is forced to agree to extreme measures. As they say, you need to grit your teeth and break down the entrance, because it is impossible to get into the apartment in any other way.

Most often, the bolts of locks are cut off if they are visible in the gap that exists between the door leaf and the frame. The crossbars are cut with a grinder or a hacksaw. Lock cutting is used in critical situations when the door urgently needs to be knocked down. Usually, after this the door leaf has to be completely changed.

When working, it is necessary to take into account the features of modern door designs. Not all modern doors can easily cut off the hinges with a grinder. There are structures equipped with a protective mechanism and anti-removal bolts, which cannot be cut.

What is not recommended to do

In some situations, they try to glue key fragments together with glue. However, this method is ineffective, since there is a possibility of the fragment becoming jammed, which further complicates the matter. Also, chemical elements may get inside the lock, which will require replacing the cylinder.

Gentle methods

How to remove a broken key from the cylinder? This can be done in the following ways:

• Self-tapping screw. Applies only to thick keys. It involves drilling a hole at the break point and screwing a self-tapping screw into the lock. Then the self-tapping screw is grabbed with pliers and removed along with the fragment.
• Jigsaw file. This is one of the most effective ways. The file must be inserted under the key and turned so that the teeth are located on top. The fragment is grabbed and removed.
• Fishing hook. This is a rather difficult but effective method. To remove the remains of the key, unbend the hook by inserting the serrated tip into the hole. When the key is engaged, you must carefully pull it towards you.
• Pliers. Pliers are in demand when there is a large piece of debris protruding from a keyhole. First you need to lubricate the lock, and then pull out the key. Everything must be done carefully, without using excessive force.
• Vibration. This technique is recommended if the key inside the disc lock breaks. First, the pins are lubricated. Next, using a thin screwdriver, the code elements are installed in their original position. Then the lock is tapped with a hammer. Under the influence of vibration, the fragment is pulled out and removed using pliers.
• Pulling out the fragment with a metal tube. Recommended for lever locks. You need to take a copper or brass tube that fits onto the protruding pin. Next, you should melt its end with a soldering iron and attach it to the fragment. After hardening, the tube must be pulled out along with the broken key.

Unusual ways to remove a broken key from a lock

If the key is broken, you can open the door using one of the unusual methods. Even professionals use them:

1. A brass tube is placed on the fragment and heated with a soldering iron. After the tube has cooled, part of the key is removed in the usual way;
2. the tip of the bent fishing hook is inserted into the slot and the rest is fished out. The method is suitable when the fragment has gone deep into the keyhole. The main thing is to hook it with the barb of a fishing hook, and then carefully pull it towards you;
3. The two parts of the key are glued together with superglue and pressed tightly against each other. After a few minutes of waiting, the entire key is removed from the lock cylinder. Broken keys, even if they are firmly glued, can no longer be used.

What to do with interior doors

Interior doors also often fail. They can be opened with a tongue. You will need a handy tool with a wide working part. A knife with a strong handle and a wide blade is suitable for the job. Using a knife, the tongue is pryed off, which helps to instantly open the door.

If there is no tongue, unscrew the lock screws using a screwdriver and remove the secret mechanism out. If you don’t have a screwdriver, you can unscrew the screws with a regular manicure file.

If the latch is triggered at the wrong moment, a thin wire is placed into the keyhole. This facilitates the actuation of the key and the opening of the latch.

There are other methods that are used depending on the type of locks and the specifics of the entrance doors:

• A crowbar is inserted into the gap between the door leaf and the frame. Mechanical action causes the lock bolts to move, and the door can be opened;
• in critical situations, door hinges are cut off using a turbine or grinder;
• When slamming an interior door, use a plastic card. It helps if there is a latch. The card is inserted into the doorway. If the lock design is complex, you will have to unscrew all the bolts.

On a note! The door latch can be pressed using available tools (knitting needles, pens or pencils).

In what cases will a magnet help?

A powerful neodymium magnet will only help you if the key is made of iron. Brass products that are now made for modern locks are not attracted to a magnet.

Keys made of brass most often break because they are not reliable and cannot withstand increased load

What to do if the padlock is jammed?

Padlock mechanisms are located outdoors and are always exposed to the external environment. If the key in a padlock is broken, you can use the vibration method by tapping the lock with a hammer. In this case, you must act carefully so as not to damage the bow. The rest of the key may fall out due to vibration, and the lock will remain intact.

Sometimes the key doesn't break, but simply gets stuck inside the lock and won't turn. Since the internal elements of suspended structures rust, machine or vegetable oil helps to activate them.

Oily substances reduce friction between parts. If that doesn't work, take some spray lubricant and generously lubricate the inside of the lock through the hole. After this, try to insert the key and turn it alternately to the right and left. The lock must be held with your hand to keep it stationary.

In humid and frosty weather conditions, it happens that a lot of moisture gets into the padlock mechanism. It turns into ice and prevents the key from moving. In this case, ordinary hot water can save the situation. The castle is generously watered with it, then treated with lubricant or oil. Usually this is always effective, and even an old rusty mechanism begins to work properly.

If conditions permit, the unruly castle is placed in an active chemical composition. You can use all types of gasoline, acetone solution, weak acids, vinegar, diesel fuel. These substances dissolve rust and successfully combat corrosion phenomena.

You should not expect instant results: it will take several hours or even days to achieve the effect. After chemical exposure, any mechanism begins to work well.

Opening a door with a damaged lock

What to do if the broken key remains in the lock and there is no way to remove it? The door needs to be opened, and sacrifices will have to be made here. At best, you can damage the lock cylinder, and at worst, the lock itself.

In order to open the lock, you can use one method. If the lock is not installed correctly, its cylindrical opening mechanism may protrude slightly above the decorative trim. Then you may be able to clamp the end of the cylinder with a gas wrench and simply unscrew the cylinder. Next, you need to clear the resulting hole from possible debris, and the door can be opened using a flat-head screwdriver. If the cylinder does not protrude beyond the lining, then you can sacrifice the lining itself by tearing it off with a nail puller or chisel, and then proceed according to the previously proposed scheme.

What to do if the onions are lying in the garden and how to save the harvest?

If you don’t have a gas key, you can simply try to knock out the lock cylinder with a hammer, but this must be done after removing the internal armor plate, which is not always possible. But keep in mind that after using this method, the lock will most likely have to be replaced.

You can use an electric drill to open the door. Using a drill, you need to make a hole in the cylindrical insert, slightly below the hole where the key is inserted. In this way you destroy the tsugali - this is the name of the lock's code mechanism. Pull out the drill, lightly tap on the end of the cylinder so that the broken pins fall down and do not accidentally jam the lock. Then insert a flathead screwdriver into the hole and open the lock. If your key has a double-sided notch, then you need to drill from both sides.

You can try to completely drill out the entire cylinder of the mechanism. But for this you need to use a large drill with a diameter of 6 to 10 millimeters and a powerful drill. With this method, it is usually possible to damage the lock cam itself. To open the lock after this, you need to take a piece of strong wire and bend the tip about 1 centimeter. This is done in order to capture the locking mechanism cylinder. Insert the wire into the hole and try to move the bolt itself.

Who to turn to for help if you can’t open the door yourself

When you can’t open the doors without professional help, you should contact the housing office or the building management company. Usually, specialists arrive an hour after the application is accepted. At first they use gentle methods. If they turn out to be ineffective, you have to resort to hacking, cutting off the hinges or removing the lock from the door leaf.

After the specialists arrive, the owner of the apartment or house must be prepared for the fact that he will be asked for documents proving his identity. It’s good if your passport or driver’s license was not left in a locked apartment. When renting residential premises, tenants must call the owner and ask him to come, taking with him the necessary documents.

Calling specialists from the housing office or the building management company will not have consequences in the form of material expenses for a tenant who finds himself in a critical situation. As a last resort, you can use the paid services of commercial organizations.

Advertising leaflets with their phone numbers are always found in mailboxes or on entrance doors. Specialists from a commercial organization also have the right to demand documents from a person, but there are companies that operate without these requirements.

Some commercial firms provide further services after a forced break-in of a residential premises. For a fee, they can install a new lock or a new door.

How to prevent the key from breaking in a door lock?

Each of us can find ourselves in such a situation. In order to avoid it, you need to be more attentive to door locks, handling them with care and precision. If the lock jams, it will continue to do so in the future. Eventually it will jam completely. If the internal mechanism is jammed, it is better to repair it as quickly as possible without delaying the matter.

From time to time you need to pay attention to the condition of the key. If it begins to bend and its teeth become thin, you should replace it with a new one. It is better to throw away old keys immediately.

For preventative purposes, the lock is washed and lubricated once a year. Kerosene or gasoline is used for washing, and effective silicone-based sprays can be used as a lubricant. They protect small parts of the secret mechanism from rust and prevent small dust particles from penetrating inside. You can also install a metal flap at the larva.

Proper care of the lock and timely replacement of keys will help you avoid being in a situation where the key suddenly breaks and the lock stops working. The lock must be handled with care so as not to damage its secret mechanism and not be left outside at the wrong time.

Preventive actions

To deal with such problems, you need to periodically perform a number of actions:

1. Clean the lock regularly (at least once a quarter). It needs to be cleaned of dirt, washed with gasoline and kerosene, and lubricated with silicone grease. This substance protects the metal from corrosion and does not collect dust.
2. Place a protective cover over the larva. The cover will protect the lock from dirt and moisture. You can use a piece of rubber or plastic.
3. At the first sign of jamming of the lock, you should immediately replace it entirely or the core.
4. Handle keys and lock with care. Keys should not be used as a locksmith's tool. A strong slamming of the door can negatively affect the lock mechanism.
5. Install a second lock on the door, which will duplicate the main one if it breaks.
6. Make duplicates only in those workshops that are trustworthy.

Following these simple rules will allow you to avoid problems associated with the inability to get into your house, apartment or garage due to a broken lock.

How to remove a broken key from a car

It is hardly surprising that drivers are often interested in the question of how to get a broken key out of a car. Not all cars work with a keyless entry system or with starting the engine from the Start Stop button.

Therefore, in order to get into the car, you first need to insert and turn the key in the door lock. Next, when you intend to drive, you still have to insert the key into the ignition, turn it over and drive off.

The reasons why it ultimately becomes necessary to remove a broken key from a car door lock or ignition can be different:

• frozen water inside the door lock;
• inaccurate turning;
• mechanism jamming;
• lock malfunctions;
• low quality of the metal of the key itself;

• using excessive force, and so on.

Seeing that one piece is left in his hands, and another piece of the key is stuck in the door, the main question that arises in the driver’s mind is how to get it out of the car now.

Use of hand tools

If one key is broken, there is usually no serious problem. In most cases, the motorist has a spare key. It’s just that you won’t be able to use it. To do this, you will first have to get rid of the debris. Look into the lock itself where the key is stuck.

Consider yourself very lucky if a piece of a broken device is partially visible from the outside. That is, the metal protrudes beyond the level of the lock itself, and is not stuck deep inside.

Although the rod protrudes from the lock, it still sits quite tightly inside the larva. This is not felt when the key is intact, since the gripping area is quite large. The effort of a few fingers is enough to remove without problems.

Only part of the rod remains here. It is unlikely that you will be able to grab it with your fingers and pull it out. Also, try not to drive the sting even deeper into the larva with your rash actions.

To remove a broken key that is stuck in your car door, you can use:

• multitool;
• pliers;
• pliers;

• powerful tweezers;
• long-nose pliers;
• mechanical spider;
• side cutters;
• with wire cutters.

The idea here is to firmly grasp the protruding metal part of the stuck key, and then begin to gradually pull it out.

If you manage to pull out the fragment, do not rush to throw it away. It’s better to leave it so you can give it to the master and make an exact duplicate. This is especially true for those who do not have a spare key for one reason or another.

Bad advice

Some “craftsmen” advise using super glue when opening it, supposedly capable of gluing torn pieces of metal together. Of course, the “method” is flawed. Even the best glue is not able to bind two fragments together enough to pull the piece out. Often the fragment becomes jammed, which makes removal more difficult. The situation can be worsened if chemical elements of the glue get inside the lock. Then it will not be possible to remove the fragment “painlessly”, and the larva will have to be replaced.

Another unfortunate example is the proposal to remove the key using a steel wire. In some cases, this can actually work, but it will require considerable skill.

Alternative Methods for Removing a Stuck Key

Alas, not everyone is so lucky. It often turns out that the key is broken and stuck quite deep in the car lock. As a result, it will no longer be possible to grab the protruding part with the tool.

The situation is such that the key in the lock broke at the root and remained inside the cylinder. There is now no access to the inside of the car, or the ability to close the car. We need to come up with something.

There are several options for how to remove a piece of your car key that is stuck in the door if we are talking about deeper-lying remains.

You can correct the situation using:

• thin metal wire;
• jigsaw files;
• superglue and soda.

Now about each option in more detail.

Metal thin wire

The wire needs to be thin enough to fit into the existing gap, but also strong enough to withstand the tension when trying to remove the remaining metal.

The bottom line is this:

• find wire of suitable sizes and parameters;
• make a long tail that you will hold on to and pull later;
• make a tiny hook at the end, literally 3-4 millimeters;
• insert the wire into the gap between the groove and the fragment;
• try to catch on to the protrusion of the key;
• gently pull towards the exit of the lock.

Under no circumstances should you rush here. You may have to pull out the remaining keys from the cylinder, millimeter by millimeter at a time. Therefore, immediately be patient.

Plus, not every wire will be suitable, since when caught, the hook may align itself, and thus the element will not be pulled out.

Jigsaw file

An excellent device option if you don’t know what to do if the key in your car lock suddenly breaks and you can’t get hold of it with pliers.

If there are deeper residues that can still be caught from the inside, a file from a regular jigsaw will help. Both manual and electric. The advantage is the presence of teeth on this device. That is, you won’t have to make an additional hook.

The idea is to insert the file into the lock, use the tooth to hook the protruding part of the key and pull it towards you.

As in the previous case, take your time. Pull gradually, pulling the key out millimeter by millimeter. Only patience and your own accuracy will help you here.

Just keep in mind that the method with a metal wire, like with a jigsaw file, is only suitable for situations where the key gets stuck in the neutral position. That is, in cases of relatively easy pulling out.

Super glue and soda

The situation looks somewhat different when the key not only breaks, but the driver also managed to turn it before that. And here a natural question arises about how to open the car in such a situation.

And here a fairly old but extremely effective life hack will help you, as it is now fashionable to say. To work on removing the debris, you will need to take superglue, as well as regular baking soda.

Many people have probably heard and know about the use of quickly hardening and setting glue, but they do not quite understand what soda has to do with extraction.

Everything is easy to explain here. The combination of glue and soda gives a stronger and stronger connection. In fact, baking soda enhances the effect of superglue.

The extraction process itself looks like this:

• pour glue into some container;
• prepare a small amount of baking soda;
• find a tool that is suitable in length and size so that it is easy to insert it into the lock;
• dip a tool, a flat screwdriver with a thin blade, into the glue;

• then sprinkle baking soda on top;
• carefully insert the screwdriver into the lock;
• make sure you hit the metal debris exactly;
• hold the tool like this for a while so that the glue has time to set;
• When the desired level of setting is achieved, remove the remaining key.

The advantage of this method is that the connection is really strong. That is, you can not only get the remaining metal from a broken key, but in some cases even turn it.

Although it’s not worth taking risks and experimenting here. The main task is to remove the broken tip. And to open and close doors, or turn the ignition switch, it is better to use a spare key or a duplicate one.

A few more ways

You should not do something that the user does not understand, or the successful outcome of which he is not sure of. If the door does not open, the broken key cannot be removed, you should not make any unnecessary movements - you should immediately call a specialist, especially since it will cost much less than if the specialist starts work after several unsuccessful attempts by the user - this will cost more. A broken key can be pulled out in another way - it should be used when the lock is jammed and the fragment does not turn in any direction and cannot be pulled out. If you have a drill at hand (you can ask your neighbors), you can use it to drill out the cylindrical mechanism in the place where the fixing pins are located.

It is worth considering that if the key does break in the lock, then this most likely means that it will not be possible to return it to operation and you will have to purchase a new one. Therefore, you should not feel sorry for the old one - it can be completely broken.

The situation when the lock breaks is familiar to many and there is nothing terrible in it - the main thing is not to panic, you can always open the door, the question is how much time and money will have to be spent on this.

But even if the lock is jammed, this may indicate minor problems - a lack of care for it (there is simply no lubrication in the mechanism). Therefore, regardless of whether the key is broken or the lock mechanism is simply jammed, first of all you should try to fill in the lubricant - maybe the problem will disappear - this is where you should start.
