2. The system of claim 1, wherein the door lock system includes a thumb turn that is eliminated when retrofitted.

3. The system of claim 1, further comprising:

a wireless communication device coupled to the circuit.

4. The system of claim 1, wherein the position sensing device is an accelerometer.

5. The system of claim 4, wherein the accelerometer determines position of the drive shaft and at least one of, door knocking, picking of the lock, break-in and unauthorized entry, door open and closing motion.

6. The system of claim 4, wherein accelerometer does not require additional power than that required for determining the at least one of, door knocking, picking of the lock, break-in and unauthorized entry, door open and closing motion.

7. The system of claim 1, wherein the positioning sensing device in operation is coupled to the device that converts energy that provides for moving a bolt of the lock device to at least one of a locked or unlocked positioned.

8. The system of claim 1, wherein the lock can be manually locked and unlocked.

9. The system of claim 1, wherein the position sensing device is selected from at least one of, an accelerometer, optical encoder, magnetic encoder, mechanical encoder, Hall Effect sensor, potentiometers, contacts with ticks and an optical camera encoders.
