ABSTRACT :
This paper is proposed to describes as the car or bike`s key is missed, the key will be detected by using GPS(global positioning system) and GSM(global system for mobile communication) technologies and the microprocessor. The GSM will send a message to our mobile phone. The GPS will track the signals while the key is missed that means the key is theft. If an object is moving that time the GPS will track the signal. Suppose the key is missed in our home, by using an alarm or light to make a circuit with a microprocessor.
INTRODUCTION
The car or bike`s key is missed, that key will be detected by using GPS and GSM technologies. The GPS can locate where the key is present. The GSM indicates that your key is theft. This message will send to our mobile. For example ,the bike will be kept outside the home , the key is also present in our bike. The bike`s owner will forget to get the key himself. That time the thief will theft a bike. Due to that we can use this method , we can safe our bike or any other object`s key. The RFID key can show all the details about the car. If the key is missed, we can also use this method and to detect the key.
We can get the details about the car. The details like service charges, how many times you can put the petrol or diesel etc. If the key is missed inside our home, we can use an alarm or light in the microprocessor. It can produce a sound. But this method is used means we can manufacture an IC and then implement this method, we can detect the key is present inside the home.
TECHNOLOGY USED IN SYSTEM DESIGN
Radio frequencies based information and communication technologies such as GPS, RFID tags and Bluetooth etc. it have matured and become commercially available to potentially support automated data collection.
GSM- GLOBAL SYSTEM FOR MOBILE COMMUNICATION
The global system for mobile communication is the most popular technology in the world. Throughout the evolution of cellular telecommunication various system have been developed without the benefit of standardized specifications. It can prevent many problems related to the


compatibility, especially with the development of digital radio technology.
The GSM standard is intended to the address these problems. SM provides recommendations not the requirements. The GSM specifications defines the functions and to know required details about the key. The GSM network is divided into three major systems
1] switching system[SS]
2] base station system[BSS]
3]operation and support system [OSS]
The name GSM first comes from a group called GROUP SPECIAL MOBILE. When GSM service started in order to communicate effectively. The mobile station consists of mobile equipment and subscriber identity module.



GPS- GLOBAL POSITIONING SYSTEM
The global positioning system is a global navigation worldwide and useful tool in map-making, land surveying, commerce, scientific uses , tracking and surveillance. It measures it`s position by carefully timing the signals sent by the constellation of GPS satellites high above the earth. When the object is moving its corresponding distance, the GPS will track the signal. It is useful to identify where the key is present.
BLOCK DIAGRAM OF THE GPS SYSTEM
Using this system , we can track the signal from anywhere at any time in the world. It `s give an information about the car`s or bike`s key.


WORKING PRINCIPLE
If the car or bike`s key is theft. The car key with RFID tag, the GSM and GPS will be placed inside the tag. Even the car or bike`s key is missed, we will track the signal through the global positioning system.
The global system for mobile communication can send a message to our cellphone. If the key is missed inside the home, we can use an microprocessor to make an alarm or light. Because inside the home the key is not a moving object . so we can make an alarm. It produce a sound to identify the key. But outside, the thief will get a key with bike. That’s why the key is a moving object . for that time, we will track the signal through the GPS technology.


Most of the people kept a bike outside the home . He/ She is forget to get the key himself. That time we missed the key. If the key is RFID key GPS and GSM will track the signal and get a message to found out the key. By using this ID we know about the car or bike`s details. RFID key only can be identified. But poor people has no that key. So we can make an alarm in an ordinary key. By using this method , we can safe our car or bike or house key also.
RFID- RADIO FREQUENCY IDENTIFICATION
RFID is a generic term for technologies that use radio waves. The combined antenna and microchip are called as a RFID transponder or RFID tag and work in combination with a microchips. Depending on the tag, the energy is harvested by tag`s antenna. It` s used to power up the internal circuitry of the tag. It can communicate more effectively.


ADVANTAGES
1. Easy to know where the key is present while the key is missed.
2. RFID tag will help us to know the car or bike`s details.
3. Easy to track the signal.
4. When the key is theft, we can found out the key through GSM technology.
5. It`s less expensive ad high reliable.

6. No signal loss while we have a continuous network is available.
7. We can safe our bike or car`s key.



CONCLUSION
Because of this security system, it is too hard to an unknown person to steal the car or bike`s key .we can missed the key from the purse. We can easily identify the key and also safe the car or bike. We can also add an alarm or light. It gives a more security. Future scope is that the system should be embedded on a single chip in a key.
