Where is the receiver on the car for the key transmitter?
Does anyone know where the receiver is on the car which reacts to the key fob press (e.g. lock/unlock).
A while back there was a thread about getting more range from the key (put it up to your chin). What about getting more range from improving the receiver?

I honestly mean this in an informative, not condescending, way. I apologize in advance if it comes out sounding like the latter...
90-second physics lesson...
There are two types of radiation; Ionizing Radiation and Non-Ionizing Radiation.
Ionizing radiation has the ability to modify cells (this is the kind of radiation that can cause cancer)
Non-Ionizing radiation does not have the ability to modify cells, it can only generate heat.
RF transmitters...like our key fobs, cell phones, two-way radios, etc. all produce non-ionizing radiation.
The amount of heat a transmitter can/will generate is directly proportional to the amount of power the device outputs.
Consider this; people have been using commercial two-way radios (walkie talkies) for the last 40 years. These handheld units generate power usually in the 4 to 5 watt range (4,000 to 5,000 milliwatts (mW)), transmitting close to the user's head (you have to hold it up to your mouth to talk) with no long-term effects.
Cell phones generally transmit with a power of 250 to 1,000 mW (considerably less).
While I don't know the exact amount of power that the key fobs generate, I do know that they work intermittently for 6 months to a year, using only a 3V lithium battery to power them so, I'd put their power in the 10-25 mW range.
Short answer - You're safe to put it in your mouth and press the button, if you want.

I just got a "2002 New Features Manual" off of ebay (~ $28). The receiver is in the inside rear view mirror. It shows it on the right side of the mirror body itself, not the mounting hardware attached at the roof line. It is possible that the location changes depending on the year.
