A high security post lock according to the invention includes a hardened shell having a head member at one end thereof and an eccentric locking cam rotatably mounted at the other end. The lock is adapted to be inserted through an opening passing through a door frame and a door to secure the door. In a first or open position, the circumference of the cam is coextensive with the circumference of the shell, so that the lock can be inserted into and withdrawn from the door. In a second or locked position, the locking cam projects outwardly from the shell to prevent withdrawal of the lock and thus secure the door. Movement of the cam is limited by a pin and groove arrangement.
