In this paper, a secure parking reservation system using Global System for Mobile communications (GSM) technology has been performed. It helps the drivers from facing the problem that always occurs at the car park, such as time being wasted in searching for the available parking spaces and keep on circling the parking area until they found an empty parking spot. This problem usually occurs in urban areas, where number of vehicles are higher as compared to the availability of parking spaces. In this proposed system there are two modules have been developed such as parking lot monitoring and security reservation modules. For the parking lot monitoring module, the layout animation is used to display the parking lot status. In security reservation module, the users need to send SMS to reserve the parking lot and use the password provided to enter and exit the parking lot. Our main contribution is the system has more security than other previous research with the used of password to enter and exit
