Nope - well you are - but that is not the point. If you hold it above your head you get less range than with it touching your chin.
If you touch your chin with the fob and press it whilst holding one arm out towards the car you sometimes get even more range - unfortunately you look like you are Nazi saluting your car...
 
Presumably the same way your body amplifies your tv reception when holding the aerial, everybody must have messed with a portable aerial before right..
 
Also worked over mobile phone once. 100yds from car, the guy phoned me and held the key to his mobile as I stood next to the car. He pressed the button and the car opened :D

"(More than a few people have inadvertently fooled themselves into believing the cell phone method of unlocking car doors actually works because they tried it and achieved the desired*results — not*realizing their cars were still within range of their keyless remote devices, and the signals that unlocked the doors were transmitted the usual way [i.e., through the air], not via cellular phone connections.)"
 
Holding the remote close to your head simply increases the effective size of the transmitter antenna, since the near field RF is coupled into the body and re-radiated. A secondary effect is that you are holding the remote higher than you would normally, which also increases range.

Surely radio waves are't affected by mavity at this scale? So, assuming you have a clear line of sight anyway, how is lifting the keyfob two feet higher going to increase it's range?

He pressed it a good few times. Called me, pressed once and it worked. Hung up and tried again and it didnt work.
 
Dunno why it works but it does. When it was originally aired we put it to the test over a lunch time on our car park. Much to our surprise it works really well. Absolutely no side effects whatsoever other than I now start to go beep... beep... beep... before I sit down...;):)

Ah I remember the days getting in the loft to adjust the aerial, while getting told from downstairs how good the signal was.

"That's perfect. Leave it there"
*let go of aerial*
"Ah it's gone again, why did you move it!"

:rolleyes:

However, as the article above explains, it is impossible to use the remote over the mobile network because of massive frequency differences.
So whatever you experienced, it wasn't the ability to unlock a car via a mobile phone.
 
Worked on my old 206 and did massively increase the range. Haven't tried on the Celica as works decent enough (even though the manual states just a 1m range)
