generating output instructions causing the mobile device to output a user prompt on a display of the mobile device, wherein the user action comprises walking toward the high-fidelity zone.

9. The method according to claim 1 , wherein the second motive mode comprises a reduced processing speed having a slower processing speed than the first motive mode.

10. A system for a vehicle, comprising:

a processor;

a low-energy communication protocol disposed in communication with the processor; and

a memory for storing executable instructions, the processor configured to execute instructions to perform a selective mobile device localization for a mobile device, the instructions causing the processor to:

establish a high-fidelity zone;

determine a first geographic position of the mobile device with respect to the vehicle at a first time via a high-fidelity Phone-as-a-Key (PaaK) localization system disposed with a vehicle controller of the vehicle;

responsive to the successful determination of the first geographic position of the mobile device, switch to a low-fidelity radio frequency module for tracking changes in geographic position of the mobile device;

determine a second geographic position of the mobile device at a second time after the first time via the low-fidelity radio frequency module, wherein the second geographic position is outside of the high-fidelity zone; and

reduce, based on the second geographic position indicating that the mobile device is outside of the high-fidelity zone, a motive functionality of the vehicle from a first motive mode having a full motive functionality to a second motive mode having a reduced motive functionality responsive to determining that the mobile device is not present in the high-fidelity zone, wherein the reduced motive functionality reduces one or more mobility capabilities of the vehicle relative to the full motive functionality.

11. The system according to claim 10 , wherein the low-energy communication protocol comprises a single antenna.

12. The system according to claim 10 , wherein the processor is further configured to:

generate a geo-fence perimeter surrounding the vehicle that defines an interior portion of the high-fidelity zone.

13. The system according to claim 10 , wherein the processor is further configured to execute the instructions to:

determine that the mobile device is not present in the high-fidelity zone; and

send, to the mobile device, an output request message causing the mobile device to output a user action message responsive to determining that the mobile device is not present in the high-fidelity zone.

14. The system according to claim 10 , wherein the processor is further configured to execute the instructions to:

reduce the motive functionality to the second motive mode is further based on determining that a fob is not present in the high-fidelity zone.

15. The system according to claim 10 , wherein the processor is further configured to execute the instructions to:

determine that a key fob is present in the high-fidelity zone; and

increase the motive functionality to the first motive mode responsive to determining that the key fob is present in the high-fidelity zone.

16. The system according to claim 10 , wherein the processor is further configured to execute the instructions to:

send a message to the mobile device requesting a user action responsive to reducing the motive functionality of the vehicle from the first motive mode to the second motive mode.

17. The system according to claim 16 , wherein the processor is further configured to execute the instructions to:

generate output instructions causing the mobile device to output a user prompt on a display of the mobile device, wherein the user action comprises walking toward the high-fidelity zone.

18. A non-transitory computer-readable storage medium in a vehicle control module, the storage medium having instructions stored thereupon which, when executed by the vehicle control module, cause the vehicle control module to:

establish a high-fidelity zone;

determine a first geographic position of a mobile device with respect to the vehicle at a first time via a high-fidelity Phone-as-a-Key (PaaK) localization system disposed within a vehicle controller of the vehicle;
