1. A remote keyless entry (RKE) transmitter operable to wirelessly communicate with an RKE system of a vehicle, the RKE transmitter comprising:
- logic operable to indicate a return trip having a plurality of return compass directions and return distances to a user, the return compass directions and return distances being sufficient to direct the user from a destination back to the vehicle;
wherein the logic is operable to determine at least most of the return compass directions and return distances as the user journeys from the vehicle to the destination;
a directional lock button; and
wherein the logic is operable to define a plurality of journey segments to direct the user from the destination back to the vehicle, each one of the journey segments being determined to correspond with the user separately actuating the directional lock button for each journey segments, each journey segment defining one return compass direction and one return distance to represent a travel distance and direction for the user to travel for the corresponding journey.

Abstract
A remote keyless entry system is provided comprising a handheld remote keyless entry transmitter in selectable wireless communication with a car based entry system. The handheld remote keyless entry transmitter comprises an integrated electronic compass element and logic adapted to store a first compass direction when activated and directed towards a destination. The logic further is adapted to display a return compass direction and a return distance from the car based entry system when activated leaving the destination.

13. A vehicle finder transmitter comprising:
-
logic operable to indicate a return trip as a plurality of journey segments sufficient to direct a user from a destination back to the vehicle, each journey segment defining one return compass direction and one return distance; an electronic compass element operable to facilitate determination of the return compass directions based on compass directions generated by the electronic compass element; an electronic signal strength element operable to facilitate determination of the return distances based on signal strengths measured between the transmitter and the vehicle; and wherein substantially all of the return compass directions and return distances are determined prior to the user reaching the destination; a directional lock button; and wherein the logic is operable to divide the return trip into each one of the plurality of journey segments according to user actuation of the directional lock button. - View Dependent Claims (14, 20)

15. A computer-readable program operable to facilitate control of a remote keyless entry (RKE) transmitter operable with a RKE system of a vehicle to indicate a plurality of journey segments, the plurality of journey segments being sufficient to direct a user from a destination back to the vehicle after the user has previously traveled from the vehicle to the destination, each journey segment defining a corresponding compass direction and distance to be traveled by the user for that journey segment, the program comprising logic operable to:
-
determine substantially all of the compass directions and distances for substantially all of the journey segments while the user travels from the vehicle to the destination; determine a beginning and an ending of each of the plurality of journey segments from corresponding user actuation of a button included on the RKE transmitter while the user travels from the vehicle to the destination, thereby requiring the user to actuate the button at least three times while traveling from the vehicle to the destination. - View Dependent Claims (16, 17, 18)
