Ladies and Gentlemen, I am pleased to present you my proprietary, latest design of a door lock. It is a standard size lock that fits as a replacement for any popular cylinder lock. This lock is distinguished by an unusual, unique design that provides complete security against an attempt to be opened illegally with a pick. I have the copyright to this solution and I will be happy to cooperate in the production of this solution if anyone is interested in this mechanism. And there is something to pay attention to. The strengths of this lock are: 1. Inability to open with a pick, the lock has a double pin locking system. 2. The lock is secured in such a way that the cylinder cannot be tensioned at the same time and the correct pin positions cannot be looked for, as is the case with classic picking (see eg LockPickingLawyer). 3. The lock has a large number of combinations and virtually every key is unique. In the presented presentation, I focus on discussing the principle of operation, it is a graphically simplified presentation and please do not pay attention to graphic shortcomings. It is important to understand the principle of operation and focus on looking for weaknesses that I, as a creator, did not find. The presented lock is only the necessary minimum, only a half of the mechanism, necessary to understand the principle of operation of the mechanism based on my first idea for a combination padlock, which can be viewed on my website www.polishlocks.com
As you have already realized, the presented lock is colored so that I can use the colors to draw your attention to the most important safety issues and how to operate the lock.
And so we open the lock with the key and the opener, marked both in green. I will also mention that you can freely modify it and replace the opener with a fixed knob in the lock. Many details can be replaced with a different approach, but the merits are the most important. Here I decided to show you the key and the opener separately because it is an unusual solution (such a curiosity).
The process of opening the lock:
To open the lock, insert the key into the keyhole as far as it will go. Please note that the key does not twist like in other locks, its purpose is only to align the pins. After inserting the key into the lock, insert the opener so that the tabs enter the holes in the lock, press it down to the stop and turn it like a traditional key, opening the lock. As you can see, the opening and closing process is child’s play, quick and convenient. Now it’s time to reveal the secrets of this unique worldwide solution. Let’s focus from the beginning on the whole process of opening the lock, now I will discuss what happens step by step in the lock. Then I will discuss what happens when someone tries to pick the lock.
1. Put the key into the lock.
a. In the presented solution we have 5 pins, but as I said, it is an element for any modification. Noteworthy is the fact that the pins are cut, which makes them rough in use.
2. After inserting the key, just like in any lock, the pins align at the cylinder contact point, the red part and the lock housing, the yellow part. This pin alignment makes it possible to gently twist the cylinder with the opener. At this stage, after removing the key, if we changed our mind and did not want to open the lock, the pins will lock the lock again, they will drop down, pushed from above by springs.
3. Let’s see what happens when we want to open the lock and start operating the opener. The key is in position, the pins are raised, now we push the red both parts about 1-2mm deep into the lock to the stop. At this point, something fantastic happens. There are two independent pin locks in the lock, the upper one in the red part and the lower one, brown. Let’s unfold the lock so that you can see this moment. For this purpose, I will put out the lock housing and the red upper part that covers the locking mechanism. The aforementioned pressure of the opener causes that both locks begin to press against the pins and block them so that they cannot move up and down. This is very important for security, and I will discuss it later when we focus on trying to pick at the lockpick. So now two blue side pins or bolts begin to press against the lateral pin lock and move it towards the pins while the blue bolts fall into the grooves that allow the lock to turn fully. The second lower lock is also pressed against the pins and prevents their movement, in particular from falling freely downwards. Now we turn the opener or the knob in the version with a fixed knob and open the lock. The closing process is identical, only from the end. The key can be extracted from the lock only when both pin locks are released, i.e. in the position where the blue screws come out of the groove and the entire red element withdraws under the influence of the spring between the two parts of the lock, the inner and the outer, it is not shown in the present presentation containing only the outer part but imagine this spring which, when compressed, now deflects the entire red mechanism. Now we can remove the key and leave the lock open or closed. Now a few words about security and why even LockPickingLawyer would have a problem opening this mechanism. Each “burglar” who specializes in harmless opening of this type of lock uses the same methods, which consist of two elements.
a. Tension the cylinder mechanism to sense the pins and their position
b. Tension the pins one by one with the pick to find the correct positions.
c. Both of these movements must be accomplished at the same time. Otherwise, it is not possible to force the lock. Note that in the discussed solution it is not possible for both these movements to take place at the same time. In the first phase, the attacker will be able to freely touch and manipulate the lockpick on each pin in the keyhole, but without cylinder tension, so he will not be able to sense whether a given pin is in the correct position or not. The pins will move freely up and down in their channels without resistance. Each pin will appear identical. Now the attacker will start stretching the cylinder to feel the pin layout and, unfortunately, he will fall here. The aforementioned two pin locks, the upper and the lower one, will effectively block all the pins and prevent them from being moved even by a minimum distance, putting up resistance and masking all possibilities of feeling the mechanism. The harder the attacker pulls the red cylinder, the harder the pins will be blocked. This is what makes my mechanism invincible. I estimate that the only option is to force the lock by force, which, as we know, always takes place, but it is easy to prove for the company insuring our property. The presented lock is ready in its concept for mass production, its design is well-thought-out and the manufacturing method is possible. Perhaps a Polish company such as Gerda or a foreign company such as Assa Abloy will be interested in this solution. I invite you to cooperation.

In this section you can read about my modification to standard Pin Tumbler Lock.
Modification (variant A)
Hello today is 10 FEB 2019 and I made new video and present you new modifications to standard Pin Tumbler Lock in order to make it much more difficult to pick.
Another modification (variant B) below.
Hello, today 29.JAN.2019 I decided to publish my latest invention. Unpickable pin tumbler lock. This is crucial and important improvement over standard pin tumbler mechanism. I added few new components making this famous mechanism fully unpickable in my opinion.
Those two are: Manual Pin Lifter and All Pins push plate. They are working together. Now in order to open the lock you need to slide in the key pushing the main pin in the bottom of the plus and the same time manual lift all pind towards key using Pin Lifter.
Those combination prevents to standard lock picking procedure. Now you can watch my video where I explain all details.
Few remarks: This design presented on video is the simplest upgrade to standard pin tumbler mechanism. i didn’t concentrate on design and final look but rather to explain working principia of my upgrade, benefits and correct operation. Please keep in mind that the final version could be different. As Potti314 already pointed that bottom springs are not necessary etc. The shape of keyway could be different as well etc. Please consider this presentation as rough and not pay too much attention to design. The basic working procedure is correct.
How to protect against simple reverse picking by pushing the key pins down?
There is very simple solution to protect this mechanism against such a attack:
I have checked this, it is really easy to design this mechanism in such a way that pushing the key pin from inside down will be possible but not below the shear line level so you will not be able to open it. This is possible if the key pin movement is not the same up and down. The space to move down will be not enough to align key pins with the shear line. It will be possible only by moving pins up by manual pins lifter. The presence of springs no matter here.
Below solution for reverse picking method: Please consider that red pins could be made from neodymium magnets and blue from steel. The key is from brass and the plug and case as well. Please notice that final configuration could be different like: magnets only in slot 2 and 4 and some red pins from brass and steel. The keyway could be different as well and the shape of the key like normal one etc.
