Today is great day 01 September 2018 Warsaw, Poland.

The global story begins now.

Welcome to my official internet site from Poland. I am the owner of this site and the inventor and owner of the brand new and unique lock mechanism I called Polish Combination Lock (PCL).This is the place where you can find all basic information about this lock mechanism. This mechanism is in my opinion the most secure 100% mechanical mechanism ever created. You can watch my presentations here in the “video presentations” section or directly on my YouTube channel. I am explaining in a few videos my new approach and the unique construction of the PCL mechanism.

I organized the Worldwide decoding challenge in order to prove the highest level of security.

This solution is under Copyright and if you are interested to copy it or use part or entire solution you should obtain written permission from me.

You can contact me directly:

Below is an example of the padlock with PCL mechanism mounted inside.

I am looking now for any Investor or any Company to cooperate and to start word-wide production of this amazing solution.

Please share this information as broadly as possible among all your friends we can change the world together and make it much more secure to live. 

I believe that my new lock mechanism will open new chapter in the world security and people start to use it worldwide.

Best regards,

Zbigniew Olejnik
