How Keys And Locks Work
One of the most important things and probably the most underestimated one is a key. But did you ever think about how a key works? There are so many different kind of keys and locks that we cannot explain them all. We want to talk about a tumbler lock.
Several pairs of pins are pushed into the core with elastic force. Now the core is blocked and the lock is closed. If you want to open it you have to put a key in it. The right key presses all pairs of pins align with the edge of the plug and you can now rotate the key.
