ABSTRACT:
A new and improved anti-carjacking apparatus for a motor vehicle includes an open door sensor assembly and a first timer assembly actuated by the open door sensor assembly. A first switch actuator assembly is activated by the first timer assembly for a first predetermined period of time. The first timer assembly controls a ready state for the first predetermined period of time. A second timer assembly is actuated by the first timer assembly. The second timer assembly is actuated after actuation of the first timer assembly by a second predetermined period of time which is a delay period. A deactuation switch assembly is capable of being manually actuated by a person and is capable of deactuating the first timer assembly and the second timer assembly. A first alarm signal assembly is controlled by the second timer assembly and by the deactuation switch assembly, such that when the deactuation switch assembly is in a deactuation state prior to expiration of the delay period of the second timer assembly, the deactuation switch assembly prevents activation of the first alarm signal assembly, and such that, when the first alarm signal assembly has been activated, the deactuation switch assembly is capable of deactivating the first alarm signal assembly.
