ABSTRACT:
To prevent the unauthorized unlocking of van doors equipped with safety rod locks, the lever of the safety rod lock is held to the door by a retainer clip. The retainer clip has an extending tongue with apertures in it that passes through the door into the van. In the van, there is a dead bolt which may be actuated by a key cylinder inserted from outside the van through the door to cause the dead bolt to enter an aperture and lock the extending tongue of the retainer and hold the retainer in place so that the lever cannot be moved to unlock the safety rod lock. A second key actuated member or solenoid actuated member is actuated to move a cam in front of the first key slot so that it cannot be unlocked until the second cam lever is moved out of the way. Thus, a sequence must be followed using two different actuating means to unlock the door or lock the door.
