There's possibly also a little inducer that matches a coil in the fob that allows just enough power induction to activate the response. Like a low-power proximity card. At least, that would be the case if I were designing it.The slot in the g2 dash doesn't have a working cylinder. It's only purpose is to get the fob as close as possible to the sensor in case you have a dying fob battery. So with a g2, even without a slot for the key, it's not a loss. Just move themfob closer to the center console and push the start button.
