1. A burglarproof device for use in a vehicle capable of emitting a human voice comprisinga remote transmitter having a plurality of control keys including a first, second, third, and fourth keys;

  • a remote receiver in radio contact with said remote transmitter;

    a decoder connected to said remote receiver to determine which of said keys on said remote transmitter is being operated;

    a latch circuit connected to said decoder for activation by said first and second keys of said remote transmitter;

    a central door lock controller connected to said latch circuit for activation by said latch circuit upon operation of said first key of said remote transmitter to lock doors on the vehicle;

    a timer connected to said latch circuit;

    a counter connected to said timer;

    a re-triggerable timer connected to said counter;

    a vibration detecting circuit connected to both said counter and said re-triggerable timer;

    a wireless sos system transmitter connected to said timer;

    and a voice system connected to said decoder, said latch circuit, said counter, said central door lock controller, said timer and said wireless sos system transmitter;

    said voice system connected to announce locking of doors of the vehicle upon a signal from said central door lock controller upon activation of said central door lock controller by said latch circuit upon operation of said first key of said remote transmitter and said timer and said counter activated to enable said counter and said re-triggerable timer to receive a signal from said vibration detecting circuit upon vibratory movement of said vehicle wherein said voice system receives a signal from said re-triggerable timer through said counter to issue a first audible voice warning, further vibratory movement detected by said vibration detecting circuit connected to send a second signal through said counter to said voice system to issue a second audible voice warning, an additional vibratory movement detected by said vibration detecting circuit connected to send a third signal through said counter to said timer to said voice system to sound an alarm sound after a predetermined time set by said timer, upon still another vibratory movement detected by said vibration detecting circuit before the alarm sound is finished sounding, said voice system controlled through said timer will emit a continuous alarm sound;

    said voice system connected for control through said decoder upon operation of said second key of said remote transmitter to emit voice confirmation of deactivation of burglarproof effect wherein said timer and counter are shut off from receiving a signal from said vibration detecting circuit;

    said voice system connected for control through said decoder upon operation of said third key of said remote transmitter to emit voice aid to locate the vehicle;

    and said voice system connected for control through said decoder upon operation of said fourth key of said remote transmitter to repeatedly emit voice calls through said wireless sos system transmitter.
