At the time we replaced the BCM (sorry, I said PCM earlier), we also replaced the crank AND cam position sensors. SKIM makes the most sense at this point. I had it towed to my favorite Jeep guy, and gave them BOTH working keys so they could re-program them to the SKIM if that's what it turns out to be. I only left one of my two remotes though, will they need the other?
One thing I will say about this Jeep...though I've had more electronic problems with it BY FAR than any other car I've owned, it invariably breaks down in a place that causes me minimum grief. Like my driveway....or the parking lot of my local Diner, where I can leave it all day.....and NOT at Midnight in the Airport parking lot, or in a winter storm on the highway. It seems to know where home is
