[@maximilian2772]

i dont see link to buy transparent lock

[@waldevv]

Should be noted that the reason why lockpicks work is manufacturing tolerances, which causes all the pins and holes to be slightly out of alignment and different size. So when you try to push the pins up, the one that is the most out of alignment will click first, and that causes the plug to rotate ever so slightly so that one pin will stay at the shear line and can no longer fall back down. Then you keep that up until all the pins click and stay at the correct height and the lock will open. That's also why you need to keep turning the lock and hold the pressure.

[@kreinova2747]

This what i am not understand before and not clearly informed. How does the spring not springing 😂 Why just it doesn't goes down and i Understand it must the the tumbling mechanism. Thus you got the answer. Thanks🎉

[@ryanchowdhary965]

How do the driver pins hold them selves in place

[@timothybrand8509]

It seems it's because the Driver Pins are not actually connected to the Key Pins so that there can be a gap between the two, so by trying to turn the Plug, part of the Plug (the walls of the hole for the pins possibly) make their way into that gap and hold it in place. I may not be right since I also just learned about locks but I feel bad that nobody answered your question.. I hope this helps :)

*Hello this is the lock picking lawyer*

[@StefanoBorini]

If LPL has taught me anything, this padlock is vulnerable to shimming and having the pins pushed fully above the shear line. Inexcusable design flaw that has been known to padlock designers since the 1980s.

[@SS-rk7bu]

I wish you also show us when wrong key is inserted what happens? Anyway thanks for video Like

[@scorpio6587]

Would it be possible to use magnetic force to pull the latches inward?

you'd pull everything up.

[@scorpio6587]

@ not the pins, the latches at 5:35.

@@scorpio6587 Same thing, you'd attract the whole lock, and in the hipotetic case only the latches were attracted, they'd need a very powerful magnet to counter the spring and torque of the plug mechanism, since the latches and the plug are connected.

[@scorpio6587]

@ I see. So basically, the magnet locks everything together.

[@EngineeringMindset]

Great question and great answers. This is exactly the mindset I like to see.

[@jamesallen74]

Two questions for confirmation. After inserting the KEY fully into the PLUG, which part of the KEY comes in contact with the KEY PINS? Is it the small VALLEYS on the key or the small PEAKS on the key? Your animation shows it's the valleys, not the peaks. Also with no key inserted, what prevents the key pins from coming all the way down and some falling out of the lock?

[@elijaholeary5139]

i would guess that the pins are magnetic?

[@MrJeremiah135]

@@elijaholeary5139 I think that it must be cylindrical holes that are wider than the key slot itself. That would allow the spring to push it all the way against the end of the cylinder and keep everything in place. I say that because it looks like all of the key pins are perfectly aligned at the bottom even though they are all different sizes.

[@tomjames2569]

You need to do rotary screw air compressors.

[@bianca30rafaella92]

I don't get it, the shapes on the key is what keep the pins in the position so you can turn the plug. With a picking tool, how do the pins stay on the sheer line? Cause as soon as i release the first pin and move to the second, i can see the first one back in it's original position. As it would be normal i think. So am i doing something wrong or what? I'te tried with 3 different locks. Door locks, not pad locks, but still....
