Abstract
A method and system for providing a distance to target vehicle finder function for remote keyless entry is provided. The method and system include enabling a vehicle finder function from a portable device and transmitting a low power signal from the portable device to a vehicle onboard receiver. The method and system further includes determining whether the vehicle onboard receiver receives the low power signal from the portable device and enabling a low power vehicle finding response. The method and system also include transmitting a high power signal from the portable device to the vehicle when it is determined that the vehicle onboard receiver does not receive the low power signal from the portable device, and enabling a high power vehicle finding response when it is determined that the vehicle onboard receiver receives the high power signal from the portable device.
