Problem statement: This study presents a new design for an anti-theft protection System as an inexpensive solution to protect cars from theft and from non-authorized users by using microcontroller-based system. Approach: Three stages of protection to strengthen the security of the car: Firstly, when the user access the car by the car key and entered the wrong password, the power is remain disable. If the power shifted by others, the second level comes by disabling the starter motor from being turned on, so the stolen keys cannot turn the car on. Results: Assuming that the thief or non-authorized person connected the starter motor directly to the car battery, the car well not turned on because the directional valve is set to the case where the fuel is fed back to the fuel tank and no fuel is pumped into the engine, which is the third security level. Conclusion/Recommendations: A microcontroller is programmed using C language, a directional valve is controlled by microcontroller to take the proper valve position to allow the engine to start or not. This system is worked properly and tested successfully
