摘要：
A method of indicating a proximity value representative of the distance between a key fob (202) and a vehicle (102) includes transmitting (304, 406, 504) at least one locate signal from the key fob (202) to the vehicle (102), transmitting (364, 468, 562) at least one response signal from the vehicle (102) to the key fob (202) in response to the at least one locate signal, performing (362, 462, 510) RSSI measurements of either the at least one locate signal or the at least one response signal, and displaying (318, 412, 514) the proximity value on the key fob (202) based on the RSSI measurements.
