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.
“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.”
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.

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

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 :p
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???
Basically using your skull as signal magnification :thumb:
The bone in your skull reflects the signal so (assuming you are looking towards you car) more of the signal goes in the direction you are looking, ergo is stronger and can travel further??
MAde sense in my head anyway lol.
The higher you hold it in the air, better chance of a line of sight transmission of the unlock signal.

"Apparently when you do this, your skull acts like a dish, and your chin is the focal point.........."
Stolen from a forum somewhere that Google lead me... :)
So if you lie down and point it at your chin it works at a greater distance as well then?
Because your body acts as a antenna.
As it's been mentioned, your body acts as a crude amplifier. It's the same principle as to why the radio gets clearer when you stand next to it. Also, first post. WHEE! EDIT: Oh yes, the science part. Fluids in the oral cavity, aliens and voodoo are equally applicable.

the oral cavity and fluids in our mouth couples with the key fob turning our head into a nice big conductor which extends the range of the fob by a few car lengths
your body can act as a reflective plane for the radio waves, kind of like being an antena.
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. With all the fluids in your head it ends up being a nice conductor
KarlHungus

Gonna take a total gues at this and say...
Its just a case that your holding the keyfob higher and the signal clears obstacles and interference easier.
redrooster303
20-09-10, 15:19
its because your skull is a close enough approximation to a parabolic reflector making it possible for your head/skull to direct some extra energy/signal forward giving you extra/more distance.:):thumb:
“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.”
I guess we all ended up at the same Googled web site then :)

Google FTW
The mouth is full of liquids which conduct electricity, which makes it a very good amplifying antenna for the radio signal sent out by the fob, extending its range.
I wonder if it works for wifi...

You are capacitively coupling the fob to your head. With all the fluids in your head it ends up being a nice conductor. Works to some degree deffinately, but may only add on another 15-20 feet.
And also, it'll only work if the alarm fob in question is a radiowave one :p
Your body acts as a natural antenna, plus holding it high (at chin level) helps too! :)

thinks its because the shape of your head/skull is similar to a parabolic reflector. this aparently slightly extends the radiowave signal a bit! (not 100% sure this is right tho):)
PeterStoba

The higher the 'fob' the less objects in the way to block the RF signals...
Your head magnifies the signal ie head acts like a natural antenna
Your body is a natural antenna and will help extend the length you can transmit the signal.
your head helps reflect the waves in one direction giving an improved chance of a wave reaching the destination.

Your whole body is now the antenna.
Your body will work like an aerial for a number of radio waves, just not a very good one. I do think El Waneyo is right about the height helping too.
It's never worked for me.
It works because I'm not hibsrpish.
The fluids in your head are a conductor and so extend the antenna (the extension being your head), giving you better range with your car 'fob'
it uses your body/skull as an antenna, bounces off! :thumb:
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...using this in this way creates a conductor

when you place fobs near your face it allows you to shoot laser beams from your eyes. this in turn allows you to permanently destroy the annoying alarm.

the water in your body is conductive so acts as a booster.
It uses your body as an amplifier antennae.
Basically, your skull is acting as a spherical lens, collimating the radiation from your keyless entry emitter, thereby improving the signal coupling between the two and While your head will absorb some RF energy, you should keep in mind that even a modest refraction can dramatically amplify the signal at the receiver.
Therefore, your head can redirect ten to one hundred times the total energy towards the receiver, giving a signal increase at the receiver of 5 to 50 times more albeit in a collimated cone.
Works best on the chin as your head acts like a natural spherical lens "think satellite dish"
Works the same if you hold a small fm radio by its antennae the signal usually improves.
not if its an infra red one :D
IR will need line of sight, or specs to reflect off :P
AmdOverclocker
20-09-10, 17:50
It extends its range because the fluids in your head make it be a better conductor. having it at head height also makes it extend its range, because the higher they key fob is, the longer the wireless signal will travel.

pomfretbantam
20-09-10, 17:52
your body amplifies the RF signal on a vertical plain as opposed to the horizontal plain the fob transmits giving it further range in a direct line
the oral cavity in skull amplifies the signal
Because you are raising it higher than you would normally so the RF (Radio Frequency) is less likely to meet obstructions.

20-09-10, 18:11
the remote signal when you're holding the key fob to your chin Use's your head to extend the key's wireless range by a few car lengths. able to make contact with the car by holding the remote to the chin.
I think a fair few are picking up the wrong end of the stick, thinking water makes for a good Ariel / booster for RF radiation :D

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.
Head acts like an antenna, increasing the range at which it can transmit the signal.
The Body acts as an antenna , i noticed with my hand as well as head they both improve the signal.
Because its connected to my private parts (not directly you dirty lot) and this is a mega amplifier and bolts the signal 10 fold :D

20-09-10, 19:00
The reason for the car fob signal transmitting further when held to the head has not been precisely determined. The most accepted theory is that near contact with the skin creates an electromagnetic junction and uses your body as a very large antenna
as you are raising the height of the fob you are therefore increasing the range of the fob.

You are capacitively coupling the fob to your head making your body part of the antenna. The extra height only helps if you don't normally point the fob through the window.
its all to do with your facial hair, if you have a shave it wont work as good, that is why cavemen could hunt mammoths with just spears :confused:

You are raising it higher than you would normally so the RF is less likely to meet obstructions and your body acts as an antenna
the fillings in your mouth act as an extender for the range also the metal plate in some peoples heads can make you unlock it from a mile away.
Basically the shape of hour heads and the composistion of the bone makes our SKULLS (not brain) perfect for boosting signals, think of it like a megaphone for your car fob signal. However this doesn't always work depending on the shape of your skull. IF you put it to a dogs head, it wouldn't work. But its well worth a try to see your dogs reaction :P
Your skull and brain act as an antennae and extend the range by approximately 3 to 5 metres. This is achieved by the electronic waves emitted from your brain, as part of general work.
:rolleyes: Shame iPhone 4 users can't use the chin for signal boost... Maybe they'd help you take a dump better though

The fluids in your head are a conductor and so extend the antenna (the extension being your head), giving you better range with your car 'fob'
Because you are raising it higher than a lot of obstructions like other cars in a car park so their's less things blocking the way of the signal.

Oh well.

If your body acts as an antenna it doesn't have to amplify anything to increase distance reached. For instance I can put a bigger satellite on my house and pick up more distant signals with no increase in power to the LNB. That said I agreed with your post too that holding the thing in the air is probably helping too :thumb:

I don't know the answer to this, but I'm actually inclined to agree with El Wayneo..
Putting a bigger dish on your satellite just increases the amount of things the dish can collect and put into the LNB. Its like using a bigger spoon to put sugar in a coffee. You can use a bigger spoon to collect more sugar without increasing anything to do with the coffee cup - and you still end up with more sugar going in.
However, to transmit something over a bigger distance under all the same conditions, you need to amplify it...
I don't know the answer, but I'm just trying to say you can't compare a passive receiver to something that actively transmits :)
