    • An anti-theft device for a car or other vehicle comprising an axle-locking mechanism (ALM) having a movable fork device, contained within a housing, and in turn the housing is coupled to the vehicle body, mounted on the vehicle chassis, for example the floor of the vehicle. The fork device extends to interlock with the axle, thereby immobilizing the vehicle. The interlocking may occur either with indentations formed on the axle, or via a set of protrusions welded to the circumferential surface of an axle, or otherwise appended to an axle. The ALM can be configured to interlock on one of the front axle, the back axle, and the drive shaft, i.e., the three places to make these things happen, which are three (3) possible locations for the interlocking. The fork movement ranges from disengaged to fully engaged, with the interlocking and engagement of the fork against the surfaces of the axle. The fork movement is either swinging, perpendicular or lateral sideways movement. In another embodiment, a pair of arc-shaped brake shoes may be used to clamp against the axle on opposite sides to immobilize it.
