TLDR Spare key has been "lost" somewhere in the truck for over 2 years, is there a way to find it using its radio frequency?
Yesterday I drove for about an hour, before receiving a call from my friend that my truck key fell out of my pocket in his car. I drove the remainder of the trip (5 hours) without shutting off the car, to make sure I could get home in time for a meeting and he's going to be mailing me the key. Upon arriving home, I finally shut off the car, but decided to try to restart the vehicle, it fired right up.

So either, I have an electrical issue -OR- after having thoroughly vacuuming and cleaning out the truck recently, I moved the "lost' key into transmission range of the starter radio. I'm going to be yanking all the mats out and checking under all the seats, hoping that it isnt in one of the ventilation ducts. For clarity, previously my truck required my PRIMARY key (the one I left behind) to be present in order to start the truck, so I'm scratching my head.
Aside from physically tearing the car apart, is there a way to track its location using its passive radio signal?
