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.

U.S statistics shows that a car is stolen every 28.8 sec, adding up to more than 1 million cases of auto theft each year. Vehicle theft has become the nation's first property crime, costing more than $7.4 billion a year. One of insurance companies in Jordan said, striking that the phenomenon of car theft is not a private problem but had turn to insurance companies, especially if the type of insurance is comprehensive, there are 25 insurance companies in Jordan and are daily dealing with an almost fixed rate of 3-10 communications about car stealing. Many car owners rely on a car alarm system to protect their vehicles from criminals. Unfortunately, even the most sophisticated car alarm systems are not enough to prevent auto theft (Hunter and Ashjaee, 1988; Reynolds et al., 1990). Wahab et al. (1997) described a real-time vehicle location tracking system which uses the current technologies of Global Positioning System (NAVSTAR GPS) to provide continuous position and velocity tracking of moving vehicle (Alaqeeli et al., 2003), presented a novel signal acquisition and tracking method that reduces the number of operations, simplifies the HW implementation and decrease time needed. MATERIALS AND METHODS This new method is very fast processing of incoming GPS samples that satisfies real-time requirements (Bullock and Krakiwsky, 1994), stated that Digital road maps are being used increasingly throughout the world as they become more available. Five major digital road map suppliers are focusing their efforts on producing databases that support vehicle navigation functions. Of a total of 147 vehicle navigation systems in the world, 89 use in-vehicle maps, of which, 35 employ map matching and 31 offer real-time route guidance. Vehicle navigation systems are limited by the maps they use, so the availability of inexpensive, complete and seamless navigable digital road maps remains as an impediment to the wider use
