A dual range vehicle remote where in the ranges are affected by changing the gain of the vehicle based receiver.

摘要

A method for operating a controller (34) of and a remote keyless entry system (RKE) (32) to provide for short distance functions that are actuatable from a key fob (38) at a shorter distance (D1) from the vehicle (30) than other long distance functions. This may include receiving a desired type of radio frequency signal (52); actuating a high gain mode (104) of a receiver (36) of the controller (34); detecting (106) a message (62) from an acceptable remote keyless entry transmitter (38,50); decoding (110) a function code portion (63) of the message (62); changing (114) the receiver (36) from the high gain mode to a lower gain mode if the function code (68) is not a long distance function; decoding (116) a remaining portion (70) of the message (62); determining (118) if the remaining portion (70) of the message (62) was decoded properly; and performing (120) the requested function if the remaining portion (70) of the message (62) was decoded properly.
