Check this out guys... Chipped keys are a huge issue too.
“The great key uh oh”
“I have an 01 WJ 4.7 with skim. My wife lost her key in November last year, and yesterday while fishing up river, my key fell out of my pocket into the mighty Kuskokwim River. What are my options for replacing/reprogramming/eliminating the skim? I have steel keys that work for the doors, and will turn it over. I am 400 air miles from the nearest dealership in southwest Alaska. Chrysler said any dealership can program keys based on my vin, our nearest dealer said Id need to bring either the Wj in, or at least my key. Since Im sol on that, and not spending 6-8k one way to freight my WJ to Anchorage, what can I do?”
