i dont know if anyone has already said this b/c i dont feel like reading them all so...this happened to me. i was told that when the car roles of the truck at the dealer the put a sticker or write it on the car somewhere. so here are some places i was told to look....pull out the ashtrey look on back and sides for a sticker, there is also a trey on the back of the console look there, then i was told to look under the hood near the vin numbers and under the fuse box. good luck
