7. The distance measuring system according to claim 6 , wherein

the user interface determines the electronic key has exited and entered the vehicle based on at least one of a detected position of the electronic key, a detected vehicle function, and a detected vehicle operating state.

8. The distance measuring system according to claim 1 , wherein

the distance data gathering component comprises a position detecting component configured to monitor successive locations by which the electronic key travels.

9. The distance measuring system according to claim 8 , wherein

the distance data represents the successive locations; and

the user interface system is configured to calculate respective estimated distances between each of the successive locations, to estimate a distance travelled by the electronic key based on a sum of the estimated distances and to output the distance information based on the estimated distance travelled.

10. The distance measuring system according to claim 1 , wherein

the electronic key includes user controls configured to generate control data communicated to the user interface system to perform vehicle functions.

11. The distance measuring system according to claim 10 , wherein

the communication component is configured to communicate the control data to the vehicle user interface system; and

the user interface system is configured to calculate an estimated distance travelled by the electronic key based on the distance data and control a display to display the distance information representing the estimated distance upon the vehicle performing at least one of the functions controlled by the control data.

12. The distance measuring system according to claim 1 , wherein

the user interface system receives the distance data upon determining the electronic key has entered the vehicle; and

the user interface determines the electronic key has entered the vehicle based on at least one of a detected position of the electronic key, a detected vehicle function, and a detected vehicle operating state.

13. The distance measuring system according to claim 1 , wherein

the user interface system is configured to communicate the distance data to a server external of the vehicle.

14. The distance measuring system according to claim 1 , wherein

the user interface system is configured to receive other vehicle distance data from other vehicles and compare the distance data to the other vehicle distance data.

moving an electronic key a distance;

creating distance data based on the distance travelled by the electronic key;

detecting the entry of the electronic key into the vehicle;

communicating the distance data to a user interface system of the vehicle; and

operating the user interface system to create distance information based on the distance data and output the distance information.

16. The distance measuring method according to claim 15 , wherein

the operating of the user interface system includes

calculating an estimated distance travelled by the electronic key based on the distance data; and

displaying the distance information representing the estimated distance.

17. The distance measuring method according to claim 15 , wherein

the moving of the electronic key includes operating a pedometer configured to count steps taken by a user carrying the electronic key based on which the distance data is created.

18. The distance measuring method according to claim 17 , further comprising:

determining the electronic key has exited the vehicle;

communicating an initial count value as the distance data upon determining the electronic key has exited the vehicle;

determining the electronic key has entered the vehicle; and

communicating a final count value as the distance data upon determining the electronic key has entered the vehicle.

19. The distance measuring method according to claim 15 , wherein

the moving of the electronic key includes operating a position detecting component configured to monitor successive locations by which the electronic key travels.
