    Bit of general knowledge now...

    Why does touching your car alarm fob to your chin extend its range?

    Prize is one of these:

      You are capacitively coupling the fob to your head. With all the fluids in your head it ends up being a nice conductor

        you can extend the distance your alarm will activate by holding the key fob under your chin making contact with your skin. Your body is a natural antenna and will help extend the length you can transmit the signal. Try it and see from a farther range with and without contact to your chin.

        Lol whatever.

          Your brain works as an antenna/satalite or somethin.

              Because you are raising it higher than you would normally so the RF (Radio Frequency) is less likely to meet obstructions.

              Some people think its because your body acts as an antenna which is rubbish as RF doesn't work like that.

                That's about right.

                  Essentially you're using the blood, saliva and all sorts in your head to be an aerial for the remote. Only adds an extra couple of car lengths onto the range though.

                  Bit pointless on most modern cars as the reception is normally a fairly large distance anyway combined with the speed a car unlocks it means unlocking from further away doesn't really gain anything for you...unless you have some dodgy system that only works a few meters from the car.

                  This will only work on radio wave fobs and not IR ones as you can't turn your eyes into IR emitters.

                    Its the same with mobile phone signal though, i use my head to get signal!

                      Because it turns your head into a big fleshy/bone aerial. The waves are also diffracted off the shape of the skull rather like a satellite dish I believe

                        I would hazard a guess that extraterrestrials randomly subjected human targets to signal generating amplification nodes that react in range of radio waves.

                        It would explain why this trick has never worked for me.

                        But i guess the real theory is the body acts as an antenna and amplifies the signal partially. Theory.

                          Because your head will act like and aerial amplifying the signal

                            So if i pick up dog and stick my key fob next to its head it'll work as well???
