Intelligent key port aka fobgina question

Cjanik

I like to think of it this way , hopefully it will make sense to others too:

think of the RFID chip that they put in pets in case they run away. There's no batteries or whatnot in it, you just hold a scanner right above it and it will read it. The FOB is the same way. It does have power to allow it to transmit at a distance, but remove that power, and its the same thing as a pets RFID tag, meaning it can still transmit, just has to be very close to the reader.
