In this paper, the authors propose the design and construction of an advanced car security system using GSM (Global System for Mobile communication). It uses the GSM mobile communication networks to transmit alarm signal and control instruction. The control and communication between the user and the proposed system are achieved through a Short Message Services (SMSs) protocol available in the mobile phone. If the car door is illegally opened or the car is vibrated, an alarm will be activated and it send SMS message to the owner's mobile phone immediately and automatically.
