Re: Keyless entry question.
From what I recall seeing in a drawing of the keyless entry system, the RFID transmitter/receiver is actually located in the door sill (under the floor trim, IIRC). The only sensor on the door handle is the capacitive body proximity sensor (similar to a touch sensitive light dimmer in your house) located on the backside of the handle to trigger the unlock function after the RFID system IDs the FOBIK.
While I can't be certain, I would think the sensor on the handle is just a "dumb" sensor sending a generic signal to the "brain" of the system to unlock the door(s). The security part of the process would be when the RFID senses and identifies your individual FOBIK.
