%X This paper focuses on the design and development of a security system for an automobile using GSM technology and electronic circuit which is being used to prevent or control the theft of a vehicle. The case of car hijacking has become so rampant that it has become a threat to the world leaders. Some of them cannot drive their expensive cars without escort plus the sounding of siren to scare the evil perpetrators. The necessity of car security cannot be overemphasized by car owners due to high cost of purchasing car nowadays. Car security system using GSM and Electronic circuit had been designed, which can operate in two ways: receiving signal / command from the car owner through the mobile phone or by taken decision by itself using electronic circuit. The signal received through the mobile phone that serves as input to the circuit and immediately sends signal through transistor TR1 and TR2 to the 555 timer IC1 to other transistors in the circuit and output of one transistor serves as input signal to another. The output signal from the PIC 16F84A or CD 4017 demobilized the central lock system and brain box of the car. The demobilized central lock system and brain box can be reset by calling or sending another signal through the mobile phone to reset the brain box.
