At present most of the public people are having their own vehicle. Theft is happening on parking at some in secured places. The vehicles safety is extremely needed for vehicles parked in public places. We need to provide the security whenever there is any unauthorized persons using the bike, car, doors opening by giving horn by alarm. Another important feature is the vehicle cannot run for unauthorized persons the lock will not open. Vehicle tracking and locking system must be installed in the vehicle, to track the place and locking engine motor. The place where the vehicle is parked, is identified using Global Positioning system (GPS) and Global system mobile communication (GSM). When the attempt of theft is identified, the responsible people send SMS to the microcontroller, then microcontroller issue a control signals to stop the engine motor. Authorized person must send the password to controller to restart the vehicle. This is very secured, reliable and low cost .
