In this paper we gave a review on anti-theft control system for vehicles that helps to prevent the vehicles from theft. Nowadays security of automobiles from theft is common in parking places has become an important. an efficient kind of systems are introduced. We can use various kinds of sensors like proximity sensor, microcontrollers with GSM, vibration sensor are used to implement.
