Car anti-theft device is an electronic device that can be used as a security device. It is used as car security devices to secure cars against theft. It is an electronic watch dog, because when installed to a car door, and if somebody touches the door, it sounds an alarm.
The unit is built from discrete semi conductor device. It is relatively simple in both its operation and analysis. One particular feature of this project circuit (car anti-theft device) is its versatility. The circuit can be adapted for other applications. All the Information necessary for its realization is contained in this project write-up. Chapter one contains the introduction to the door alarm system, Chapter two contains the circuit analysis and component review, Chapter three contains the research and methodology adopted, Chapter four contains the design and construction while the work was concluded with Chapter five.

 

 

CHAPTER ONE
1.1                                                        INTRODUCTION
The rate of increase in car theft in this part of the world has reached an alarming rate. In the rave of this development, engineers in this country have been performing researches aimed at providing a lasting solution to this endemic act . This research team in an attempt to proffer a lasting solution thought of exploring the electronic car anti-theft device techniques as possible remedy.
The implementation is divided into two subsystems: the alarm and the vehicle immobilizer subsystems.
The importance of this design cannot be over emphasized since it helps to reduce the rate of vehicle theft within our society.
For instance, when there is an intruder into the vehicle, the system will immediately and automatically demobilized the car after few seconds the intruder moves the car thereby blowing an alarm the status of the car and preventing the car from being stolen.
This automobile security system is manually operated demobilizer. Few of the many auto-motive theft-prevention systems allow a vehicle to start and temporarily run before disabling a critical component, such as the fuel or ignition system.
In case of hijacking, the driver can leave the car safely, and then use any phone to send out some commands and remotely cut off power or gasoline supply, so as to stop the car from running and get back the car easily. In such case, the vehicle snatcher will not be in a position to harm the vehicle owner.
Car security system has been very popular in recent times and widely used in most cars and automobiles owned by companies, business organizations and even by some private individuals who can afford the cost.

1.2                                                    AIM AND OBJECTIVE
The main aim and objective of the design and construction this project is to create a comfort in the minds of vehicle owners or users when their vehicles are parked or stationed anywhere without much fear of car-theft.

1.3                                         SIGNIFICANCE OF THE PROJECT
This device functions as an electronics watch dog. This device functions as a major security alarms  used in an cars which can also be used in residential, commercial, industrial, and military properties for protection against burglary (theft) or property damage, as well as personal protection against intruders.

1.4                                                 SCOPE OF THE PROJECT
A car anti-theft is an anti-theft mechanism that prevents an automobile's engine from starting unless the correct ignition key is inserted into the ignition slot. One of the advantages of a car anti-theft system is that the car owner does not have to remember to activate it - its operation is automatic. The device is considered as a passive anti-theft system since it does not require action from a person to make it work. One disadvantage of the system is that car keys with the embedded transponder are more expensive and time consuming to replace if lost and usually requires a visit to a car dealer. Most new vehicles have a car anti-theft as standard equipment, but aftermarket or add-on car anti-theft are available for older cars or vehicles without factory-installed car anti-theft.
Car anti-theft devices are integrated into the vehicle’s circuitry and engine-management system. They automatically interrupt the power to multiple electronic circuits, usually the starter motor, ignition and fuel pump circuits, when the specially coded key is removed from the ignition switch, or the vehicle is shut off.
Only if the correctly coded key (or other coded element) is used and recognized by the system will the circuits be enabled, allowing the car to start. car anti-theft keys typically have a transponder or resistor embedded in the head to communicate the code to the engine-management system.
If the correct code is not recognized, or someone attempts to start the vehicle by some other means – such as hotwiring or breaking the ignition lock cylinder – the system will remain armed and prevent the car from starting.
An engine car anti-theft should always be at the core of any car theft deterrent system. It is the most effective means of preventing drive-away theft.

1.5                                           LIMITATION OF THE PROJECT

• For the device to work, the owner must put ON the ignition
• Car keys with the embedded transponder are more expensive and time consuming to replace if lost and usually requires a visit to a car dealer.
• The system can cause accident if not de-activated in time.
