There was also another key, called by
Polybius βãλãνάγρα, made like a small screw, and having a corresponding female screw in a bolt affixed to the door.

A staple A is fixed to the outside of the door, into the upper part of which three loose pins B B B are fitted; these pins drop into three corresponding holes in the bolt C, so as to fasten the door when the bolt is pushed in to its full extent. The key D is a straight piece of wood, and, at one end, there are three pegs E E E, corresponding in position with the pins in the lock. The key is inserted lengthways through a slot F, formed in the bolt, and then the pins in the key, corresponding with the vertical holes
