    Hold the key fob up and against your chin while pressing lock or unlock. Itll extend range by 20 or so feet. No i am not kidding, nor is this a joke.

    I forgot to mention that i was aware of placing the key fob against my head method, but i was looking for something more technical that involved hardware or something.

    Be careful, there is a thief's trick that reaches out for the fob as it hangs on your door jamb and tricks into opening your car as it sits out front.

    They just use an antenna to capture the proximity signal from the car remote. Since the proximity signal only has a range of a few feet, unless you literally keep your key next to the door you have nothing to worry about.

    Watch this video.

    Well, if you believe the NYT:

    Remote Car Key

    Suppose your remote car door opener does not have the range to reach your car across the parking lot. Hold the metal key part of your key fob against your chin, then push the unlock button. The trick turns your head into an antenna, says Tim Pozar, a Silicon Valley radio engineer.

    Mr. Pozar explains, You are capacitively coupling the fob to your head. With all the fluids in your head it ends up being a nice conductor. Not a great one, but it works. Using your head can extend the keys wireless range by a few car lengths.
