THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES AND ASCERTAINS THE NATURE OF THIS INVENTION AND THE MANNER IN WHICH IT IS TO BE PERFORMED

DESCRIPTION OF THE INVENTION:-
The invention relates for proof for an electronic Auto Door lock alert the driver to take the key out while getting out of the car. If the doors are locked and the key is inside the vehicle, then this system is used to open the door instantly.
BACKGROUND OF INVENTION:-
If the vehicle user accidently closes the vehicle door without taking the key outside, then the doors will be locked. Either one need to bring the spare key or call the mechanic to open the door. To avoid these circumstances, there should be an alternative and immediate way to open the door without taking more time.
OBJECT OF THE INVENTION:-
It is an object of invention to provide an electronic unit for alerting driver/occupant of vehicle not occupying driver seat when key is in the key slot.
STATEMENT OF INVENTION:-
Accordingly the invention provides an electronic full proof auto door lock system comprises an electronic control unit comprising key sensor key slot of vehicle control in the dash panel; a driver sensor mounted in driver seat and a blue tooth system interfaced to the lock control mechanism; and speaker means to give beef sound alarm; the said sensors and blue controlled by the electronic control unit by a software program as per the flow diagram herein illustrated.
DRAWING:-
The invention is described with reference figures of accompanying drawing wherein;

Figure 1 shows the sensors and blue tooth system and speaker provided in dash panel of vehicle;
Figure 2 shows flow diagram of function of electronic system as the software program loaded.
DESCRIPTION:-
An electronic full proof auto door lock system comprises an electronic control unit comprising key sensor of key slot of vehicle control in the dash panel. A driver sensor mounted in driver seat and a blue tooth system interfaced to the lock control mechanism. A speaker means to give beef sound alarm. The said sensors and blue tooth controlled by the electronic control unit by a software program as per the flow diagram herein illustrated in figure 2.
The system of full proof auto door lock system comprises of Key sensor, Driver sensor, speaker and Bluetooth. The whole system is located in dash panel as shown in the Figure 1.
The Key sensor is used to sense the presence and absence of the key in the key slot. The Driver sensor is used to sense the presence and absence of the driver/ customer in the driver seat. Speaker is used to make the beep sound to alert the driver. The Bluetooth is the interface media which is connecting the Vehicle and the Driver, through which the PIN can be accessed from the customer Mobile. If the PIN matches with the predefined PIN, then a signal has to be sent to door lock to open.
The key sensor is checking the key's presence in the key slot and the driver sensor is checking the driver in the driver seat. If both are presence, then this system doesn't work. If the driver is not presence in his seat and the key is in the key slot, then the signal is to be sent to make the beep sound for 10 seconds. This is to alert the driver. If the driver either took out the key from key slot or sitting in the driver seat, then the beep sound stops. If the driver doesn't care about the beep sound, then the doors are to be locked after 10

seconds of beep sounds. If the doors are opened, then the beep sound will keep on continuing.
Once the doors are locked automatically when the key is inside, then the driver cannot open the door. To avoid this situation, the system of the present invention comes into action. There is a predefined PIN number which is set by the customer to the Vehicle. The driver has to send the PIN number to the vehicle through the Bluetooth media (eg: Mobile service). If it matches with the predefined PIN, then this system sends a signal to the door lock to be released. Then the driver has to sit at the seat or take out the key outside, otherwise the beep sound will continue until that or again the door will be locked.
In the current system even the driver comes out by keeping the key in the key slot, the doors are locked automatically. So the driver / owner cannot get in to the vehicle.
The Benefits achieved by this invention are:
- The driver can open the door instantly by activating the full proof auto door lock system of the present invention.
- No need to search for alternative key to get in the vehicle, when the key is inside the car.
- Avoiding the tension for the driver, when he is trapped anywhere.
- Time saving by just avoiding alternative key searching.

WE CLAIM:-
1. an electronic full proof auto door lock system comprises an electronic control unit comprising key sensor key slot of vehicle control in the dash panel; a driver sensor mounted in driver seat and a blue tooth system interfaced to the lock control mechanism; and speaker means to give beef sound alarm; the said sensors and blue controlled by the electronic control unit by a software program as per the flow diagram herein illustrated.
