Abstract
A vehicle door lock adapted for use with a door latch also operated by an internal lock-unlock pushbutton and/or handle and characterized by a second tumbler assembly angularly spaced around the barrel relative to the usual first tumbler assembly and arranged to lock the barrel and the associated latching lug in the angular position of the second tumbler assembly and such that the latching lug will then lock the corresponding internal manual actuator. This tube prevents one, like a burglar, to open the vehicle doors by maneuvering with a wire around the glass plate of a vehicle door and by pulling up the internal pushbutton.
