A device localization system for a vehicle and a mobile device configured as a Phone-as-a-Key (PaaK) is described. The system includes a fob-free mode for performing remote control vehicle features using a selective mobile device localization technique that reduces motive functionality of the vehicle, based location of a user performing the vehicle control during the remote-control operation. The system determines a geographic position of a user using a single Bluetooth® Low Energy (BLE) antenna, and establishes establish a high-fidelity zone based on a change in mobile device position. The system reduces a motive functionality of the vehicle, based on the selective mobile device localization, from a first motive mode having a full motive functionality to a second motive mode responsive to determining that the mobile device is not present in the high-fidelity zone.
