Split key lock

A lock that uses gears to move part of the key into contact with the pins. The pins are otherwise inaccessible, and therefore they cannot be picked. The parts of the key are held together by magnets.

The idea comes from this reddit post: https://old.reddit.com/r/lockpicking/comments/coigqa/could_you_pick_that_lock/
