ABSTRACT OF THE DISCLOSURE Disclosed is an improvement in the lock mechanism described in U. S. Patent No. 3,073,143. The improvement comprises barrier walls on the bolt which prevent a shim-type pick device from opening the lock mechanism. The barrier walls are positioned to prevent the pick device from tripping the locking member which locks the deadlock actuator in the locked position.
