We obtained a couple of these Chrysler boxed lock sets from a closed dealership. They are complete with coded door and hatch locks, a key module and two, precut FOB’s. I’m curious If anyone knows their function or if anyone can use them. I was told by another Crossfire owner they are useless without a new engine computer. I find that hard to believe. Anyone help? Anyone need one? They are Chrysler issued in sealed Mopar boxes.
