This entry comes to you courtesy of the fact that I've heard this myth told to me more than once in the past few weeks my friends and complete strangers alike. My car's keyless entry remote, for lack of a better word, sucks. I practically have to be next to the car to get it to work. Alas, plenty of the aforementioned people have given me the tip to hold the remote to my chin with my mouth slightly open to increase the range of the remote signal. Is this just an old tech wives tale, or is there something legit about this voodoo car magic? Read on for the answer...
Although it sounds absolutely bonkers when you first hear it (and actually it sounds just as crazy even after you do some research on it), this actually works. And for good reason, too: The oral cavity and fluids in your skull do some kind of crazy wizardry to the remote signal when you're holding the key fob to your chin. It's kind of like the reason why those ancient "rabbit ear" TV antennas gave you better reception when you were touching them.
The New York Times asked a Silicon Valley radio engineer, Tim Pozar, for his take on how the trick turns your head into a DIY antenna.
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 key’s wireless range by a few car lengths.
If you ask William Van Winkle, it's a lot more than a few car lengths. He wrote this article for Tom's Guide earlier this month and totally confirmed that it increased his car's remote control effectiveness by about twice the length that it was before:
One step back beyond the point of being out of range, I confirmed that the remote didn’t work. Then I raised the remote, pressed it to my chin, and squeezed the button. I heard a “chirp!” in the distance and saw the headlights flash. Huh. So I started walking backwards. All in all I was able to back up 42 steps, roughly 85 feet, before I was no longer able to make contact with the car by holding the remote to my chin.

Wow, color me stunned. My friend told me this about 7 years ago, and for some reason it always stuck with me-but I just assumed it was just another of his creatively dimwitted suggestions. I guess in this case I was wrong.
For the longest time my girlfriend thought I had some weird tick/habit, not realizing I was using my sizable noggin' to extend my car alarm's remote range. When she finally found out, she had one of those "OH! Now I get it!" expressions and was relieved their was some method to the madness :D
since i'm constantly losing my car in the parking lot, this has been a lifesaver on more than one occassion!
when the television remote control isn't working right, i point it toward my eyes and it works! something about the light bouncing off the eyes and to the receiver... not sure if this is healthy or not, but it works!
I use this trick when pulling into work, trying to open the garage door (that way it's open so I can just back right in). Works like a charm. Also works when aimed at your temple.

I point it towards the window behind me-I figured the IR was bouncing off the reflective surface. It's really handy, since I've got my TV on a turntable, but not the cable box- when the TV is turned around, I can still use the remote on the obscured cable box by bouncing it off the window.
