This actually might be unpickable. But the small space of keys (6^6 combinations) makes me think you could just fabricate every single key and test them one by one, if you were really determined



If you can test one key a second (which is unlikely), that's over 12 hours to try all the keys, not to mention having to lug over 800 pounds of keys to the lock in the first place. It's possible, but certainly impractical.


That would be 46656 keys. I don't think this is feasible.


You could create a single mechanically adjustable key and a device to automatically try every combination.


Yes, this is a much better idea. might be hard to make such small actuators to get the vertical pinmovement once it's inserted, maybe you could use tiny pneumatic pistons or something


It looks extensible to me? I don't see anything keeping you from making it 6x (or 36x) harder by adding one or two more pins.
