Note to moderator: I think this post doesn´t go advanced because this lock is not high security but if considered so feel free to remove it from here to advanced section.
I was driving my car and saw this shiny padlock on the ground. Stopped and picked it up (easiest picking ever) and studied it - disc detainer lock, this is way too difficult - so I just didn´t even try to open. Until some evening when bored I picked it with doublesided pick and after 20 seconds it was open! I was a bit confused but anyway I got it open. Bonus is that when it was open I could decode disc postitions!
This chinese lock has 7 discs and cuts are made in 20 degree intervals. Each disc is 2mm thick. So I filed this key from oak, it doesn´t show well in the picture but there are 3 different cuts in this key. I will make a proper key from steel later. But no hurry as this wooden key works well. Well, I´m a carpenter
There is a hologram saying ISO 9001 top security. What does it require from manufacturer to stamp that in this like piece of crap?
