Hold your fob a foot to the side of your head. Back away until it stops working. Take 2 more steps back to be sure. Then put the fob to your forehead. It’ll work again.
It’s true, but not because your skull acts like an antenna. It’s because the signal is being reflected by the skull. You can actually just try it out, the range of your car keys will extend when you hold them to your chin.
I doubt enough signal reflect of off your very radio wave observing skull to make much of a difference at all, it’s most likely a placebo effect and the real reason it extends the range is because you are holding the key fob higher, so it has a better LOS with less obstructions, and it has a better chance to bounce waves off of the very reflective concrete on the ground up to the sensor of your car.
Organic materials are absolute crap at reflecting wireless signals, they are much better at absorbing and scattering them.
There is absolutely no way this is true. I need to see some evidence to believe this. (I work as a wireless technician)
I’ve done it. It does work.

Let us know what you think after you try it!
Science is cool.
