I’ve always put the key behind my head when doing this, and can confirm, it extends the range through experimentation.

I thought for sure I’d be absorbing it with my head but I definitely get extra range.

vs holding it out at arms length but same height? Ground interference is a thing.

I can confirm that holding the remote next to the head doesn't work, but touching chin, temple or the back of the head does extend the range. This works not just with car remotes, but also with garage door openers.

My favorite place (and yes I do this since I saw the Top Gear) is under the chin, pointing the fob/key upwards and opening my mouth. So it doesn't use the skull's cavity but the mouth's (or so I think/believe)

Have you tried standing on one leg, and touching your nose with the free hand. Vast improvement over the amatuer technique

Yes, holding at same height. I did not know about ground interference! Thanks.
