Bought on a whim at an online auction before I realized it won't work for my Truck.
Probably VIN locked to another vehicle as well but if you know a way around it its free for the taking.
I downloaded the programming instructions as well to save you 5 minutes...
Will work on the following:
2003 Ram V8 5.7 L Hemi
98 - 03 Dodge Ram, Dakota & Durango V8 5.9 L, V8 5.2 L and V6 3.9 L
99 - 03 Dodge Ram, Dakota, Durango and Jeep Grand Cherokee V8 4.7 L
I haven't even plugged it in so we're both rolling the dice here...
