are you programming from scratch (as in you are starting with no key that is programmed) or do you have 2 programmed keys and you want to program more? I BELIEVE if you have 2 keys already you can program more your self wthout the use of the special tool the dealerships use. If you don't have two, you have to take it to the dealership. Look on google how to do it urself Search "Program PATS key" I'm not 100% on this so i would double check
