Opening the lock: preliminary considerations

When we find ourselves having to open a closed door, the key of which has been inserted in the lock on the internal side; the main thing is to breathe deeply and calm down. A cool and calm mind will always work more diligently than if we are in distress.

Although our goal is to solve the situation with our own hands, we must be aware that sometimes this will not be possible. So it is advisable to have the A locksmith’s card available, in case we necessarily have to use their services.

The effectiveness of these opening methods will be governed by the closing conditions themselves. This means that, if the door has been closed with just one push, we can open it without major inconveniences, since we will only have to remove the key and take care of the slip. Otherwise, if the key inserted inside is turned, in this case it is best to call a locksmith directly; since the opening procedure will be much more complex.

How to open a lock with the key in it

We have two alternatives when it comes to opening our door; the first is to try to move the latch, to open the lock directly without removing the internal key. The second will consist of removing the key and then trying to open the door without any hindering element.

METHOD 1: Plastic bottle

We will start with the procedure that does not require removing the key and from here, we will increase the difficulty. To get started, you will need:


  • Plastic soda bottle.
  • Scissors or cutter.

Step 1: Cut the top and bottom of the bottle, to leave only the central body of it. Once done, cut out a rectangle roughly the size of a mobile; Try to stretch the plastic so that it is as straight as possible.

Step 2: Push the door, to reveal the slip a little more and make the task easier. Now being careful not to cut yourself, insert the plastic into the door at the height of the lock. The goal is to get to the slip or latch.

Step 3: Once the plastic is located, we will proceed to pull the door. At this point we will be making two movements: on the one hand, we will try to raise the plastic to the height of the slip to move it; while at the same time, we pull the door to open it. If you perform the technique correctly, you will open your door without major setbacks.

NOTE: If you notice that the slip is very stiff, proceed to spray it with soapy water. Sometimes, the lack of maintenance of the locks makes the cylinders difficult to turn and the latches have a heavy drag, so opening our door could be almost impossible. On the other hand, try not to use your ID or bank cards; as they could break in the process.

METHOD 2: Wire

If the previous procedure did not work, we will have to try to remove the key that is inserted in the internal side of the lock. To start you will need:


  • Strong wire, clips or hair clips.

Step 1: Stretch the material you have chosen, until it is completely smooth. If you use hair clips, you will need to cut off the rubber tip or else it will make the task more difficult.

Step 2: Slowly insert the wire through the keyhole, the idea is to try to push the key from the outer side of the cylinder.

Step 3: Apply a little pressure and tap the wire gently, trying to push the wrench until it drops. This technique is extremely effective, so if you apply it correctly you will get good results.

METHOD 3: False bumping

Like the previous method, this one aims to remove the key that is placed on the internal side of the bolt. To open the door you will need:


  • Copy of the key or another key that fits perfectly in the bolt.
  • Hammer, stick, dress shoe, or any blunt object.

Step 1: Insert the key into the keyhole and using the blunt object of your choice, deliver a sharp, sharp blow to the head of the key.

NOTE: The kinetic energy of the blow will be transferred from one key to another, thus managing to remove the interior with the impulse. Generally this technique has good results; But if after trying for a period of 30 minutes to 1 hour, you notice how you have not been able to open the door, it is best to call a professional locksmith to solve the situation.


The goal of this article is to provide you with a free, quick and easy alternative; to people who need to open a lock with the key in place, in order to solve a problem.

Apply these techniques only on locks that you own or with the explicit authorization of their owner. Also, take into consideration that performing these methods in public spaces may be frowned upon by other people or by the authorities. Remember that breaking and entering, damage to private property, invasion of private property, theft, theft and misappropriation; they are criminal offenses.
