Most of the anti-theft systems available on market, are the alarm types that audibly deter some thieves away but do not prevent one抯 car from being stolen and also may not be good enough to meet the growing complexity of theft in the country. This paper presents a simpler and a more efficient car anti-theft system that provides users with improved security by the use of efficient access mechanisms and immobilization systems. Access mechanisms were put in place to request authorization from the user and a hidden button which gives permission to start the car when it is pressed. Immobilizers where put in place to disable car in case it is stolen. The system was based on the ATMega168 microcontroller programming which involve the use electronic components such as limit switches, LEDs and transistors. The programming concept follows the graph theory well known as state machine implementation in Microprocessing and the language adopted was the C programming language. General Terms Automation, Microprocessor/Microcontroller programming, intelligent wireless sensor programming. Keyword smicrocontroller, car anti theft, security, electronic circuits, state machine. 1. INTRODUCTION Anti-Theft systems have been in existence since individuals began stealing other people's property and have evolved in order to stop increasingly complex methods of theft [1]. The first anti-theft devices to be built were all mechanical devices and were generally locks of various kinds. These have evolved over the years and are still in fashion today. These include steering wheel locks,
