#2241: Locompass

A Yale lock works by having a key drive pins radially outwards until they no longer stop an inner core (orange) from rotating inside its housing (yellow).

This design can be compromised by anyone with a wire (insert wire, drive one pin upwards out of the way, put circumferential pressure on the barrel to keep it there -and repeat until all pins are raised).

Today’s invention makes picking such a lock significantly harder.

Instead of one set of pins there would be say eight sets arrayed circumferentially.

The required key would be star-shaped in section and could not easily be substituted for by any collection of wires or skeleton keys, due to the limited space and level of dexterity required.

The key would carry a red dot at the 12 o’clock position, to enable correct insertion into the lock.
