Detector or transmitter?

What you need is a device like an EPIRB that is constant transmitting but only for about 6 feet. So when you get close to the door it opens and puts the ignition in to run position. ...

Something that would do polling,,, reciever transmits a hello beacon about every 4 minutes and the transmitter says yes I am here.. Once beyond the 6 feet range the remote can not transmit far enough for the main unit to get the echo so auto shut down occurs...
