Abstract
Methods and apparatus are provided for a combined vehicle keyless entry and garage door (GD) opener fob. The fob comprises a receiver, transmitter, processor, memory, user activated function switches, and preferably a display. In a GD function learn mode, the fob memorizes the signal parameters of a GD activate signal received directly from a nearby GD opener. In the normal GD operate mode, the fob transmits a replica of the GD activate signal using the learned signal parameters stored in the memory. The optional display preferably tells the user that the learn mode is active, prompts the user to operate the nearby GD opener during the learn mode, indicates whether the learn operation was successful or not and shows when the fob has returned to normal (non-learn mode) operation. The GD modes of the fob are entirely self-contained and do not depend upon the vehicle electronics system.
