Think about it, now you have a transponder device in your pants pocket say 12 hours a day. I assume it's putting out some kind of signal. Probably not a big deal, but then again some of us can use a little chlorine in their gene pool.

 

Funny, but I believe it uses radio frequency (RF) signals, which are harmless. Of course, you can never be too cautious!

 

I hope not... LOL That would suck but I heard "Stupidity Causes Cancer"

 

Not sure if that will cause a problem with spermatogenesis--but this will:

Let me preface this by saying I have NO clue how it works, BUT if I were to design one, I'd actually leave it "dormant" listening for a signal from the car. The CAR should be emitting a field from key points, like the mirrors, or door handles, or something similar (and the trunk too). When the key enters the field, THEN it responds back with whatever key sequence, negotiating with the car to unlock the doors. It probably would stay in contact every few 10ths of a second or half-second until you start the ignition.

Its probably not broadcasting while you're out of range of the car. It makes sense to do this since you'd rather discharge the 12V X-hundred amp battery that gets recharged each time you drive than the 1.5V watch battery in the key. At least it makes sense to me anyway.

That's how things like the pen on a tablet PC work; the screen emits an RF field which powers a coil in the pen, which is then capable of sending an ultra low power signal back for coordinate and pressure information. These types of things are relatively low range (2-4 inches) so I'd imagine the iKey is similar but with a powered amplifier so you don't have to rub up against your car when you want to get in.

Like I said I have no idea how it actually works, but I do have a degree in this stuff if it makes a difference to you.

 

According to my owners amnual, the key is always emitting a signal. So, when you appraoch the car, you can unlock, lock, etc. They also say that since the key is always emitting a signal, that the battery should be replaced every 2 years. It would make more sense for the key to be dormant until you actually approach the car though.

 

Harmless, like in Radar emissions?

In any event, it's not so serious that a little tinfoil won't take care of it. Always remember to remove the tinfoil while bathing.

 

Yea, tinfoil sounds like the way to go...lead skivies might be a bit too constrictive.

 

Problem Solved!! Keep the key under your hat where it won't have anything to damage! LMFAO! too funny, JBX

 

Well if that tiny battery is going to last for 2 years of continuous signal, it must be damn weak.
