Vehicle Theft Detection/Notification With Remote Engine Locking mainly aims to reduce vehicle theft to a great extent. Today vehicles are being stolen on a large number and this is the reason why this system is being introduced. To prevent the theif from stealing vehicle, this system detects if the vehicle is in theft mode and if the status is in theft mode, this system sends SMS to the user. After which the user is supposed to send back the message. This message gives command to the vehicle to lock the engine. Whenever a person tries to steal a vehicle, the PIC microcontroller is being interrupted. After which the GSM modem is responsible to send SMS to the user indicating that his vehicle is being stolen. The next step is that the user is then required to send back a message indicating to lock the engine of the vehicle so as to stop it from being stolen. The microcontroller uses a mechanism to stop the engine. In order to indicate vehicle ON/OFF state the system makes use of motors.
This project can be further enhanced by using a GPS which will also help to find the exact location of the vehicle. This information can then be sent to the user via SMS.
