You will need your pin code for your jeep that you get from the dealer to have them program this key. If you don’t have it. If you already have two working key fobs, you can buy a third key, fob and program. It yourself, saving you, the programming fee, the dealers change a lot for this, so shop around it’s, only about three dollars to cut it and can range from dollar. Eighty dollar 120 to program in i called around, and this is what it costs. Heureusement, the locksmith gave us a discount and it was 61 with tax. I plan on buying another one and we’ll have them cut it, so we have a backup in case we need. I can program this one on my own anyway, this key fob worked great with all functions. Like i said i will be buying another one.
