Very often, an old bolt, which has not been unscrewed for a long time, almost "tightly" sticks to the thread. If you apply excessive force when unscrewing such a bolt, then it can simply break. Arises pretty difficult situation, which can confuse even an experienced master. How do you get a broken bolt if there's nothing to grab onto?

The locksmith comes within a short time to fix the problem. It is good to hire an experienced locksmith to perform tasks such as removing a broken key from door lock and other settings. Locksmiths have the following attributes. They are certified to perform any locksmith task.

They take care of home security needs. They are quick to use their services. Install original locks and get replacement parts. When you use an expert locksmith, you save money as they complete the task, such as installations and fixes.

First, it is worth pouring some kind of lubricant on the broken bolt, and also, if necessary, a rust-dissolving agent. After that, the bolt is tapped well several times with a small hammer so that the liquids better penetrate deep into the threaded connection. Such a simple treatment will make removing the bolt much easier.

So, a broken bolt cannot be grasped with any tool if it is broken below or flush with the surface. In such a situation, you can drill a small slot for a screwdriver. To do this, you only need small size drill.

Did the key suddenly break in the doorknob, bolt, or lock? If so, you may find yourself in a panic with no apparent way to open the lock. You're not entirely out of luck, as these five tips will help you open the lock or prevent things from getting worse.

Avoid key insertion

A broken key may feel like you're completely out of luck, but there's still hope. Look at the broken key in the lock and see how much is sticking out. If any part of the key can be grabbed, you still have a chance to remove it with relative ease.

With the help of such a drill, a series of holes is made, and then partitions are broken out between them. The result is a groove where a screwdriver is inserted and the bolt is unscrewed with it. At the same time, they press hard on the screwdriver from above. And to unscrew the bolt was easier, the screwdriver can be clamped with a key.

If this method is not suitable, you can glue with an aggressive adhesive based on strong acids or weld a metal rod, handle or other bolt to a broken bolt. This will allow you to simply unscrew it quite simply, but it is not always possible to glue something to it with sufficient reliability, and welding may not be available, therefore this way not used very often.

Insert pliers or needle tweezers

Do not try to push the broken key further into the lock and turn it. This can make the situation worse, as the key will be much more difficult to remove from the lock when it is deep inside the locking chamber. You may be able to remove the needle nose pliers. Start by rotating the lock so that it returns to its upright position. Clamp as much of the wrench as you can with the tip of the pliers and pull the lever back with a little pressure.

Tweezers can be used if you don't have needle nose pliers. The small edges of the tweezers may make it easier to grab the tiny edges of a broken key. You can actually use super glue to get the broken key out of the lock, but it will require some care so you don't damage the lock in the process. The super glue method requires some kind of key to still be sticking out of the lock, as you want to avoid sticking glue to the locking chamber.

The third way is to first drill a hole in the bolt, then make a thread inside it (reverse orientation), and then screw another bolt inside. The other bolt will be slightly smaller, but that doesn't matter. Most importantly, now you can easily unscrew both bolts.

And the last thing you can do if nothing works is to completely drill out the bolt. To do this, use several drills. Drilling a bolt begins with a fairly thin drill, but gradually moves to an increasingly larger one.

Start by getting something small, as wide as the broken section of the key, like a paper clip. Place some super glue on the end of the paperclip, then carefully place it on the end of the broken key. You will need to hold the paperclip with the key until a connection appears between them. If the connection seems solid, gently pull back on the paperclip and pull out the rest of the key.

The super cell trick can also be used by placing super glue on the edge of a broken key that is outside of the lock, but this is only advised if no parts of the broken key are touching the lock. The cylinder cutting technique can be used on locks that you can turn so that the lock chamber faces the ground. The technique is ideal for locks and cannot be used on door handles unless you can remove the lock handle from the door.

As a result, the walls of the bolt will become thin and they are simply broken. Pieces of a broken bolt are not a problem to remove with tweezers.

This way to cope with the task always works. But there is one subtlety that should always be kept in mind. A broken bolt must be drilled strictly in the center.

If the hole is off-center, then by the time the bolt is almost drilled out, the thread will be damaged on one side, and on the other side there will still be a rather thick wall that is not so easy to break. If you drill the bolt strictly in the center, of course, such a problem will not arise.

As you understand, we are not talking about cars that "just" came off the assembly line. Typically, this problem is faced by ancient cars or those whose storage or operation left much to be desired. More specifically, we are talking about threaded connections that often came into contact with moisture. For example, it regularly comes into contact with moisture (, rain,), so it is not surprising that something has rusted somewhere.

What are the "breaks"?

Bolts can break in different ways, the most unpleasant "bolt break" is when it is cut flush, in such a situation it is simply impossible to unscrew it without special tools (drill, welding, etc.). It will be more lucky if the bolt breaks already at the exit of the thread and a little "body" remains on the surface. Firstly, in this case, you have already “torn off” the bolt, which means it will get out, which is important, and secondly, such a torn off bolt can be acted upon, for example, using pliers, a screwdriver, welding, etc.

Take the broken piece of the key with the pliers. After you have opened the keyhole, slide the pliers as far as possible into the lock and try to grab the key fragment with them. If the pliers don't fit far enough into the hole to grab them, then you can try using wire or tweezers.

Pull the broken part of the key out of the hole. Once you are holding the broken piece of key, pull it straight out of the hole. Now you can use the spare or new key. You can look in the phone book or on the Internet to find a castle blacksmith in your area. You can also use websites designed to match you with a locksmith in your area.
