I have an idea for a LPL-proof lock: Take a decent padlock, one that gets high marks from LPL, and then weld a curved steel tube to it ending at the keyhole. Then take the key and cut it in half at the head, welding a long stiff spring to attach the two halves, like a plumber's snake. To unlock, you simply stick the key bit down the tube around the bend and (with some fiddling I'm sure) into the keyway, then you can turn the key to open. Without direct access to the tumbler, I'm not sure how you'd be able to pick it.

> I have an idea for a LPL-proof lock There's a lock on his channel that he can't open. Bowley lock: https://youtu.be/qV8QKZNFxLw https://youtu.be/qV8QKZNFxLw and there's a different prototype, too: https://youtu.be/D6vioIPVzM4 https://youtu.be/D6vioIPVzM4

  there was some kerkuffle aboyut whether he actually tried to pick it, since it could be picked: https://www.youtube.com/watch?v=KS0FSzamUzc https://www.youtube.com/watch?v=KS0FSzamUzc Or maybe the picker aligned his stars when picking... not sure

    This is amazing. Thank you! There's discussion in the comments with Bowley Lock Company Inc saying that the stars did align, but we might never know

    Yes, if you push hard enough everything is "pickable" I guess But an easy code, power tools and having the lock in an ideal work position doesn't make it easily pickable. Sounds like the same useless discussions on computer security where people will discuss key sizes but not rubberhose cryptography.

Some safes I have seen have insanely long keys, like 20 cm of "trunk"... I wonder if that is the reason ...

  The lock is on the inside and the key reaches through the entire door.

To pick that, he would probably just make a pick and tensioner that has a similarly long flexible shaft.

are you perhaps talking about the forever lock? https://www.youtube.com/results?search_query=Forever+Lock https://www.youtube.com/results?search_query=Forever+Lock while difficult, it can be undone ----- making a one-off "unpickable" lock is possible, here is some to-and fro between two youtube channels about such locks: Stuff Made Here: https://www.youtube.com/watch?v=_7vPNcnYWQ4 https://www.youtube.com/watch?v=_7vPNcnYWQ4 https://www.youtube.com/watch?v=2A2NY29iQdI https://www.youtube.com/watch?v=2A2NY29iQdI Lock Picking Lawyer: https://www.youtube.com/watch?v=Ecy1FBdCRbQ https://www.youtube.com/watch?v=Ecy1FBdCRbQ But things from installation issues, to making sure tolerances are maintained while making the locks on a production line, mean that there are always some gaps left in a mass produced and installed lock.

  Here's a video of the Forever Lock being defeated with a custom-made bump key: https://m.youtube.com/watch?v=H4f1H6mYHOI https://m.youtube.com/watch?v=H4f1H6mYHOI

  Their friendly competition was fun to watch. LPL made some great suggestions for improvements, and was impressed by the idea that Stuff Made Here came up with as a physical security “outsider.”
