Abstract: The rising number of vehicle thefts is becoming an issue particularly in Nigeria where the security system is porous. Vehicle security system has become very important and vital in providing personal security for our cars. In this study, simulation and construction of a fingerprint vehicle starter system was carried out using Arduino Uno ATmega328 microcontroller. The circuit was simulated using Proteus ver8.0 via Arduino compiler programming language using embedded C language. The stages of the circuit consisting of regulated power supply, fingerprint module, microcontroller, LCD, motor output driver, and buzzer unit. The hardware prototype of the circuit was constructed on a PCB board and performance evaluated test was carried out with 150 trials in 5 stages, with 4 authorized users and 1 unauthorized user. The specificity, sensitivity and accuracy of the device was calculated. Results shows that, the sensitivity, specificity and accuracy were 96%, 97% and 97%. This implies that finger print vehicle detector will correctly accept and give access to 96% authorized users, correctly deny 97% unauthorized users, but will fail to accept 4% authorized users, and give access to 3% unauthorized users. Also, vehicle starting using the constructed device is only successful for authenticated users and we are 97% sure. Evaluation carried out under the measured performance metrics were able to be compared and analyze distribution scores of both authorized and unauthorized users with satisfactory result. The device can be recommended for vehicle security and other similar operations.

I. INTRODUCTION
The development of steam engine is one of the greatest technology of the 17th century and is the iconic invention of the industrial revolution [1, 2]. Though cars are an expensive commodity but they keep us on the road safely, gives us convenience, as well as style. Though, keys ought to be carried about and misplacing keys or losing them will result to multiple users using the vehicle without the owner’s consent, or the car can be stolen if it falls in the wrong hands. In addition, keys may be duplicated and with the rising statistics of car theft, one tends to wonder if we are offering our cars enough protection [3]. In 2020, New Zealand had the highest car theft rate worldwide, with 1,172 occurrences per 100,000 inhabitants, followed by Uruguay, Italy and the United States [4]. In 2020 about 810,400 vehicles were stolen in the US amounting to $7.4 billion lost and there were 229,339 vehicle thefts with keys between 2016 and 2018 [5]. According to Kuadli [3], car break grew in statistics by 9% in
