ABSTRACT:
An improved remotely operable security deadbolt lock device and a module therefor having an anti-theft manually operable release for a vehicle, particularly a vehicle having mating doors, such as a cargo van, includes a deadbolt having a plunger in a housing for securing the deadbolt when the deadbolt is in the locked position. The device is remotely operable by having an actuator operably connected to the deadbolt, a receiver capable of receiving a selected electrical signal to cause the actuator to be energized, and a transmitter remote from the receiver capable of transmitting the selected electrical signal to the receiver. The device further includes a manually manipulable release device including a crank arm within the housing coupled to the plunger by a shaft passing therethrough, and the crank arm having a hook and the housing having a catch for the hook. The lock device can be opened from within the vehicle without using the remotely operable elements of the device, by manually rotating a knob secured to the shaft, causing the crank arm to rotate, and hence the hook to rotate out of the catch, permitting the plunger to be manually slid into the unlocked position by sliding the knob and shaft in the direction away from the locked position.
