Method and apparatus are disclosed for key fob utilization for vehicle remote park-assist. An example vehicle system for remote park-assist (RePA) includes a key fob. The key fob includes a low frequency (LF) antenna to receive a beacon and an ultra-high frequency (UHF) antenna to transmit a return signal including a distance indicator and a RePA signal. The example vehicle system also includes a vehicle. The vehicle includes an LF module to transmit the beacon at a predefined interval, a receiver-transceiver module to receive the return signal and the RePA signal, a controller to enable RePA responsive to determining that the distance indicator is less than a tethering threshold distance, and an autonomy unit to perform RePA based on the RePA signal.
