My Jeep is a few years older than yours, but there is no need for the key fob in mine. My steering wheel does not lock, so there's no need for the key to be in the ignition. I have an auto transmission, so I leave my transfer case in neutral and the transmission in park, then I can tow. I use a brake system too... but your question was about the key fob.
