I suspect not. Its a short burst of rf and not done very frequently. (I use this technque with an key fob near an open mouth probably 4 times a year.. Thanks Car talk.

Your phone is probably worse.

#13Used to have a radio transmitter that plugged into my car lighter, and hook up to an mp3 player (or whatever) and transmit that on a radio frequency that the car could pick up. Often it would be staticky unless I set the device on my leg, and then it got a lot clearer.
Always assumed it just kind of turned my body into an extra large antenna. Probably works for a key fob in a similar way.

#14It also works holding it near your torso, don't have to use your head. Although, the joke you tell your friends is that it only works if they open their mouth and stick out their tongue like a satellite dish. The fact that it works next to your torso made me think it was just a matter of bouncing half the radio emissions towards the vehicle, thus doubling the signal. Just like someone holding an omni-directional camp…
That was my first thought too, but the OPs tests had the range only improving when held to the head.

#15I’ve found it helps to hold my key with both hands.
That would support the head-arm loop theory.

#16It's your conductive nervous system (including your brain) that is acting as a directional antenna.

During summer my bald head burns in the 5 minutes it takes to roll garbage to the curb.
Really doubt even phones are dosing us the way nature does.

Why would the duration or frequency of the burst matter if RF is harmless?

#19My brain could not connect to wifi the other day and the key fob trick worked!

As true as the notion that cellphones and microwaves cause cancer.
