However I dont have any tools, so I made a simple wrench I used the metal thing on the pen, lol, and made a few picks from bobby pins and a few from paper clips.
Anyway, I was wondering if it might have a security pins.
What I noticed is when I put a medium pressure I can rake most of the pins and push the remaining ones one by one, but I cannot open the lock... After some time I decided to keep lowering the pressure when all the pins are up. Then I could hear 2 pins fall down, the first one and one in the back I think. After I put those two pins up with minimal pressure lock usually opens.
The lock doesnt have much info, the box I got the lock in says 40mm, super hardened shackle and on the side it says a padlock of the highest protection. Its a Lince lock made in spain, I took a picture.
