    a hand grip connected to the base and with an open field between the base and the hand grip to receive an operator'"'"'s hand;

    a power lock motor in the base;

    a printed circuit board in the base to provide system controls for the handle assembly, with the system controls normally being in a sleep mode when an operator is not at the vehicle;

    a first capacitive sensor on the printed circuit board and adapted to recognize a user'"'"'s fob and to wake up the system controls when an operator'"'"'s hand enters the open field;

    a second capacitive sensor on the printed circuit board to cooperate with the first capacitive sensor to prevent actuation of the power lock motor in response to weather induced capacitive changes in the open field; and

    the printed circuit board adapted to send an unlock signed to the power lock motor after recognizing a user fob.
