There's a few that are pretty good but at a certain point you can just grind off the shackle or blow the door off its hinges.

It’s similar to the idea that the only truly secure computer is sixty feet underground, encased in concrete, turned off, and ground into dust.

I can't get hacked if I live a self sufficient hermitic lifestyle in an off the grid cabin with no electric devices.

Tell that to machete-bear.
