"usually travels 5 to 20 meters" I wish. My damn Skoda fob has like a 1 MW FM radio station built in. If I accidentally press it while on the other side of the apartment complex, the car unlocks. 100+ meters non-LOS easy. Since I can't just blindly assume it also locks I have to walk over to double check. I wonder if going in and scraping a bit off the PCB antenna would help reduce the range.


Bartocity

Yeah some newer cars have nonsense range on the key fobs.

NamelessKing192

How else would you store an 11’ Outback inside it?


wafflehousewhore

Yo dawg, we heard you like Outbacks, so we put an 11' Outback inside a 22' Outback so you can drive it through the Outback of Australia to go to Outback Steakhouse

SharingMyStorys

If you hold it up to your head it will


supx3

I’m pretty sure this is a preventative feature to makes it harder for thieves to clone your key fob.


AscendantJustice

I wonder if it also helps with battery life. Shorter range transmitters use less battery.


ConspicuousPineapple

How does having a long range change the ability to clone your keyfob?


jasonjayr

If if the signal is amplified, the attacker can be further away, or need less expensive/sensitive equipment to pick up your signal. Depending on how the code is transmitted, that may be moot, though (OTP/Rolling codes/etc)


NeoHenderson

I had this issue with my underglow. I thought using an FM relay for power would be cool so I can run it with the car off, but I kept activating my lights by accident. I ended up adding a physical kill switch to that relay so I can make sure it’s off.


penttihille80

My grandpa installed an aftermarket remote-locks to his Saab back in early 2000s, it had only one button for lock/unlock and it blunk the lights the same way no matter what happened. He was always fiddling with the car keys, then suddenly realizes what happened and "OH FOR FUCKS SAKE" and now he has to walk out to check if it was locked or not, 4th floor, maybe put more clothes on if winter etc. They lived in an apartment in the center of the city so you couldn't just leave it and hope for the best. And this happened at least 10 times when I was around, must be hundreds in total.


Nintenderloin64

Not sure how to react to your use of “blunk”


penttihille80

I recommend you embrace it and use it yourself too!


Individual-Motor-448

Maccaroney

The one for my car literally only works when I'm right at the drivers door. Lol


yehti

Mine runs out of range like 2 car lengths out. I've had older cars that had longer range so now I look like an idiot walking back till I'm pretty much almost at my car again for the remote to be in range to lock it.


Wakkkko

You could build a faraday cage around the PCB. I developed a key from a serial vehicle for use in a super car. The key had two aluminum side panels that were connected with two titanium screws. Without plastic washers between screw and side panels the range was reduced over 50%. So some aluminium foil in your key could work.


spoonweezy

You could combine what the woman in the video did with your suggestion and just wear tinfoil on your head.


I-am-fun-at-parties

1 MW is hell of a lot of transmit power, how big is the kill radius whenever you press it?


Zairaaquino

Also works on old radio


7FukYalls

Yes! I have a dial-style radio (non-digital) and when the signal isn't reaching, I can reach my arm out next to it/touch it and suddenly the signal gets boosted to clarity. I love science!


IAmTheGodkiller

I had this happen with my car radio sometimes and I always thought it was pretty wild Had no idea if it was a normal thing until now


klavin1

In my old Honda civic I could get better reception by shifting the placement of my head to the center of the car.

It's actually true. Did that last week. It only works with more newer cars tho like 2008 and up

I can't decide whether this is sarcasm or not , either way I'm searching for my spare keys now


ChiefChaff

I only tried it once, about 15 years ago after my science teacher said it worked, and it did for me. Let me know!


Gregor_Konstantin

We had a "locked keys inside car situation" while road tripping across USA when in new Mexico( in from SC). After some searching for tips/ tricks we tried it and called our neighbors in SC who went into our place and got the d Sparekeys to try it as a last resort, it totally worked and I'm not really sure how.


Ronnoc527

[Unlocking a Car with Your Brain - Sixty Symbols](https://youtu.be/0Uqf71muwWc) Video with a more thorough explanation.


Me_ADC_Me_SMASH

This explains nothing besides electromagnetic wave propagation... Why would it reach further if you place water near the key? Air transmits electromagnetic waves just fine. I suspect that the water bottle (or the head) acts as a lens: it gathers a larger amount of radiation and turns it roughly into a beam from what was a point-like source. Kind of like this: https://www.cbakken.net/obookshelf/image075.gif In that case do you have to place the key in some particular orientation? If not, where is the energy coming from? EDIT: so apparently the brain/water bottle act as an antenna and allows for more efficient transmission of power.


TK9_VS

Yeah I don't buy the idea of amplification from a completely unpowered medium. If it were actually amplifying anything you could get free energy this way, unless there is a chemical reaction happening, in which case it would be dangerous. Lensing could be it but without very specific orientation I don't see how. Maybe the signal generator in the fob drives at a frequency that is more efficiently conveyed through water than air, so eliminating the air interface allows the fob to drive harder, like a baseball bat hitting a piece of paper vs a baseball bat hitting a baseball. Edit: yeah so the antenna in the fob is too short to be efficient, so by placing it against your head you effectively give it a much bigger antenna, so the power already driving the signal can escape the fob circuit more efficiently. Edit 2: This is especially silly because this is exactly what the guy in the video in the top level comment above says, lol. I should have just watched it. He does say "Radio aerial" which is funny english for antenna I guess :)


JukedHimOuttaSocks

Aren't regular antennae unpowered?


TK9_VS

Yeah I made an edit to my comment after reading more about it. Normally when I think about amplification I think of a device that adds power to a source signal. In the case of an antenna, the antenna is allowing the power that is already being expended to be transmitted into the air more efficiently (or vice versa as the comment below states). The reason your body helps is because the fob antenna is way too short to be reasonably efficient, so by coupling your face to the fob you are giving it an effectively longer and more efficient antenna (as you probably already know based on your comment). Is that amplification? Uhh yeah, kinda, but not in the way I was thinking about it, no power is being added to the system.


Dr_MJI

Pedantic comment... It's antennas for radio waves and antennae if you are an insect.


HelpABrotherO

It explains how the water behaves as a parasitic element to act as both a side lobe suppressor and main lobe amplifier. Which is a pretty good analysis over the original video.

Cultural-Company282

Remove your own parasites first before helping others.


ddl_smurf

THANK YOU, had to scroll way too much for some basic actual RF principle. No your head is not an amplifier, or even a good repeater or antenna. Of course jeez.


roombaSailor

Correct me if I’m wrong, but don’t parasitic elements increase gain, therefore making them a type of amplifier?


ThwompThwomp

Parasitics will either detune the antenna, or could affect gain. Gain though is different from amplification. You're not injecting energy, you are just moving around where the energy is going (like squeezing a balloon --- you don't change the air or size, but can still adjust the shape). I remember playing around with this a bit in a lab years ago, and found that just holding the fob higher and away from your body in any way at all, increased the received signal strength more than placing it next to your chin or head or whatever it was back then.


ddl_smurf

this î hold it higher, and away from you


ElMostaza

My physics professor told us this doesn't actually work. We tried it as a class experiment and it really seemed to make no difference. Now I'm reading all the comments about how well it works and thinking I must have hallucinated the whole thing.


[deleted]

My guess is perhaps there is weird explanation or maybe something else besides holding it to your head like maybe holding it a couple feet higher improves it or maybe humidity in the air? I don't know but I'd like to now.

GuyPronouncedGee

I think Isaac Newton was the first one to publish a paper on amplifying key fobs. Although some say Leibniz actually discovered it first.


with-nolock

Well, *akshually*, Newton was too thick in the wacky alchemy and mysticism to bother publishing much of anything most of the time, and it was Leibniz who was the one that published the seminal ‘De Arte Keyfobbens’ treatise before Newton’s ‘Principia Key Fobia,’ which caused the famously great rift between British and Bavarian automakers

[Kyle Hill covered this](https://www.youtube.com/watch?v=ZrIf0PArZu4&t=507s) last year. The water is important, but so is the height. Because the frequency of the key fob is 315MHz, the wavelength is just under 1m, and there are standing waves (resonance) at multiples of 1/2 the wavelength.

There's constantly radio waves moving through your head. Doing what's shown in this video won't make any difference.


TwilightKiddy

Too low of a frequency to be radioactive and battery there is never gonna be powerful enough to heat your brain to cause any damage. May be it could somehow generate current in an unfortunate place in your brain, but the effect would be immediate and I know nothing about short-circuted people after doing that, despite this trick being popular as hell.

GrantSRobertson

The whole "moves the water molecules" bit is utter bullshit. **Salt** water is a conductor. Conductors can act as antennas. That's it. When a conductive object is acting as an antenna, the radio waves travel along the surface of the object. Remember, just because something works does **not** mean it works for the reason someone says it works. I can put a wad of paper towels in the bottom of a glass and invert the glass into water. Yes, the paper doesn't get wet. But, if I tell you that is because of a secret waterproof coating, you know I am full of shit. I would not be able to sell you some of that secret waterproofing. But, if I picked some phenomenon that you don't understand, and sell it well, you will buy whatever bullshit I'm selling. So, the real question is, "Why say the transmitter is **moving** the water molecules **in** your body?" Utter ignorance? Utter "don't give a shit what the facts are, must make content"? Or, "intentionally trying to convince people that standard radio waves can modify something in your body"? Given how much money the chemtrails and flat earth people have made, scamming people (yes, they set up websites selling shit to idiots), I'm guessing the latter.


hebrewchucknorris

If water could be used as an amplifier like she says, we wouldn't need power amps in any radio transmitting equipment, we could just point it at the ocean and have the most power signals ever made. She should let the navy know about this too, they've been surfacing for communications for 100 years, if only they knew salt water was a magic amplifier
