Polish Pin Tumbler Lock

Hello I made new video with all details and answer Why this is unpickable lock?

Anti Pick Pin added on first slot. There is rigid connection with driver pin. When you push the lifter button the first anti pick pin is blocking entire keyway unable the free access to the rest of pins. This is additional security level. Depends on desire security level it could be more than one anti pick pin.

Please consider that red pins could be made from neodymium magnets and blue from steel (the red part could be divided 50% upper part steel as well and 50% lower part neodymium magnet). The key is from brass and the plug and case as well. The pins could have different shapes as well. Yellow neodymium magnets 3x6mm, red and blue steel pins. Important remark: Only few selected slots with magnets like second and 4th etc. Red could be brass pins as well.

Now you can read the content more or less in your native language. Sorry if the quality of automatic translation is bad sometimes. I have checked Polish version 🙂 it is not perfect but people can understand so it should be similar in other languages.

Second round of worldwide challenge is over.

Hello, our second worldwide attempt to open my Polish Combination Lock within 7 days is over now. LockTube asked for correct code few hours before end time. I would like to thank LockTube for wonderful review and big effort to decode my lock. After those two attempts so far done by one of the best experts in lock opening I am looking for next participant. There is one gentlemen Jeff Sitar from USA that I would like to contact in order to test my solution.

Here is an article about him: https://nyti.ms/2K1wrKK

Here is video inspired me: https://youtu.be/qw_4HQMS-pk

Everything started when I had watched his video how he opens all possible safe combination locks within minutes even in bank treasury doors. This impressed me and inspired me to design Polish Combination Lock mechanism. If you read this and you have contact to Jeff or you live in US and you can help me to contact him directly it would be great.

I have already contacted with most famous lock picking experts in USA but they said that they are not experts in safe cracking lock mechanism.

Here once again many thanks to Potti314 and LockTube for they attempts to open my lock. I appreciate they effort and valid feedback a lot. Thank you very much.
