This document describes a low-cost anti-theft system for vehicles. It uses an embedded chip with a proximity sensor that requires a unique password to start the car. If an incorrect password is entered three times, the system sends a text message with the vehicle location to local police and the owner. It also deactivates the fuel injector and activates a secret lock trapping the unauthorized user inside the car until the owner arrives. The system uses common components like a microcontroller, keypad, LCD screen, and GSM module to send alerts for around Rs. 7,300, providing sophisticated security at low cost.

2. NEED OF PROJECT
•The main purpose of this project is protecting
vehicle from theft.
•Now a day’s vehicle thefts are increasing rapidly.
People have started to use the theft control
systems installed in their vehicles.
• The commercially available anti-theft vehicular
systems are very expensive. And this project is
developed as low cost vehicle theft control
scheme.

3. DESCRIPTION
•This system makes use of an embedded chip that has an inductive proximity
sensor.
•The system present in the car asks the user to enter a unique password.
•If the user fails to enter the correct password in three trials, a text message
is sent to the police with the vehicle number and the location tracked using
a GPS module. The message is also sent to the owner about the
unauthorized usage.
•Further the fuel injector of the car deactivated so that the user cannot start
the car by any means.
•At the same time a secret lock system gets activated and the unauthorized
user gets trapped inside the car and only the owner who is equipped with
the key to the secret lock system can deactivate the mechanism.

5. GSM module
•GSM (Global System
for Mobile
communications) .
•The GSM platform is a
hugely successful
wireless technology.
• GSM is an open,
digital cellular
technology used for
transmitting mobile
voice and data services.
• operates in the
900MHz and 1.8GHz
bands
•supports data transfer
speeds of up to 9.6
kbps.

6. COST ANALYSIS OF THE PROPOSED SYSTEM
Microcontroller Unit= Rs. 200
Keypad=Rs.50
LCD Screen(16*2)=Rs. 40
GSM Module=Rs.2000
4
Total Cost=Rs. 2,300
GPS system =Rs.5000,
The sum of Rs.7300

7. ADVANTAGES
•Sophisticated security system.
•Alert message to mobile phone
•Low cost
