As far as I know I just gave my vin they preprogram them to the car right off the vin. I will be picking up my three sets today I will make sure everything works I just wanted to see if anyone was interested. You have no Idea how bad it sucks knowing my car had to sit in the garage for a week when its getting colder and snow will be coming soon. I have only had it for a month and I probably have two weeks before it gets stored. Depending on where you live i might have to pick the key up at park jeep and have it shipped to your house. I will calculate shipping cost depending on where you live. I have to drive about 45 min to get them so the more orders I can do at once the better. I might tack a dollar or two on there if I have to buy a box. I would hate to have them get damaged or lost in the mail. let me know if everyone is cool with that and I will keep you posted.
