That is, open without the need for the key. No one is born learned, for this reason access to good information is a fundamental factor for the success of what we want to undertake.

Not only knowledge is a fundamental factor for success when applying any method, another essential factor is having the necessary tools for the execution of each technique. For this reason, it is necessary to have the correct information and if we add to comply with the recommendations, the best of the results can be achieved.

Life is a sum of experiences, so if you cannot open your armored lock, either because we lost the key or someone else lost it, we can assure you that from the following lines you will have an enriching experience.

We must take into account

  • Armored doors have more than one lock, so if one of them has a past key, we may have to apply the same technique several times or combine several of these to open it. This definitely complicates the procedure.
  • A certain technique applies only when the lock does not have a past key. (Bone scan)
  • The application of these methods is your responsibility, because if you plan to apply them on someone else’s property without prior authorization, you will surely have certain problems with the law.

Using a bumping key

A bumping key is a master key used to open various types of locks. They have a symmetrical or standard structure, in which the indentations o Teeth are of a medium size, which allow the internal pistons to be leveled when the key is inserted into the lock and thus deactivate the safety mechanism.

Bumping keys can be purchased at web stores or specialized hardware stores.


  • We take the bumping key and insert it into the keyhole. This must enter without difficulty, otherwise, we must find one that does.
  • If everything goes well we will notice that when we try to turn We cannot bumping the key because it does not do it completely, this is normal. But to make it rotate we must first push it with the help of a hammer, lightly tapping the key so that the internal pistons give way and can be leveled.

If it continues to be stuck, we knock again and turn the key again, until it manages to open the lock.

If we have not got a bumping key or it is not in our budget to buy one, we can make it. For this we need a blank key, the kind they use to make copies of keys.

We take a file to file the blank key until it is molded, adjusting the teeth to the same level and adapting it to the lock, so that we can use it as a bumping.

Using an X-ray

It is a very simple technique, and widely used. It is about implementing an X-ray as a tool to open a lock, but it is important to understand that this technique can only be useful when the lock does not have the key passed. If not, let’s get down to business.

What type of X-ray will we use? We will need an ordinary x-ray. The typical sheet with impressions of our bones.


We take the x-ray and cut a piece with a scissors or with any other element that can serve us. Ideally, cut a piece triangular about 9 centimeters. We do this to facilitate the handling of the radiograph when applying the technique.

  • We must put it between the frame and the door, at least four fingers above the lock, using pressure.
  • Little by little we will lower the X-ray piece without removing it from the slot. When we feel that it has jammed, it is because in that place the slip is located, also known as a latch; that’s the moving part that keeps the door closed.
  • At that point, we will pull out the x-ray piece just a little bit so that it can fit between the gap between the skid and the door frame. We will achieve this by maintaining the pressure exerted on the X-ray piece.
  • Once we achieve this, we turn the handle to its open position.

Pulling out the hinges

And what do we do if we are inside the room? It is very important to know, because if we are inside and with the key passed, without having the key to open and, in addition, the X-ray technique is not valid for this part of the door, an alternative technique must be implemented, in this case we remove the hinges.


This is not about opening the lock directly, but it will help us to leave the room. To apply it we will need a hammer and a knife or any sharp object.

  • We take the hammer and stand in front of the door (remembering that we are inside the room).
  • In the area opposite to the place where the lock is, we will find the hinges so we will take the knife and we will lift the bolts, starting from the highest hinge.
  • We will do it by placing the knife under the head of the bolt and with a lever movement we will carry it until we think it is enough.
  • Now with the hammer we will hit the head of the bolt with a movement from the bottom up until it is completely removed.
  • Later we continue with the next bolt, doors commonly have three hinges so it will be 3 bolts.
  • To finish we just have to pull the door towards us to get out. If it is a heavy door, we must do it carefully so that the door does not fall on us.

Opening an armored door may not be an easy task, but we still hope that these lines have been very helpful for you.

It is important not to forget that there are professionals whose job it is to open any type of lock and we are talking about locksmiths; It is always good to have them in the most difficult situations, those where our inexperience can put us in danger.
