Intelligent Key Question
When the battery in the Intelligent Key dies it looks as if you are supposed to put the Intelligent Key fob (not the key) into a slot that is located to the left and down of the steering wheel. My question is if the battery is dead how does putting it in this slot help. I would understand if the slot had some way of powering up the key fob but I don’t see any metal contacts or ports on the key fob.
Is it just that, if your fob dies, that you have to use your (specific) key (pulled out from the fob) to open the door and any key fob put in to the slot will start the car? How is the car going to read/recognize the fob if the battery is dead?

In the Lexus IS, when the keyfob battery dies, you can hold the fob against the start button, and after about 5 seconds, it lets out a little beep. You can then start the car.
There is something in the fob which can be read if held very closely to the device that does the reading.
The G must have this in it's little fob hole where Lexus cose to stick it near the start button.
.... I said "Fob Hole"

Ok. I'll go into more detail...
The system works on RFID (Radio Frequency IDentification).
The ACTIVE radio uses the battery to transmit a unique signal to the CAR.
Battery = range. 2 to 3 feet.
The PASSIVE chip (no battery) uses an antenna in the FOB HOLE.
Energy supplied by the car battery.
So when the battery goes out, it can still read the ID#.
Passive = Same technology used in security systems at the store when you exit.
