My original key & fob walked away... using valet key now. Can I simply grab a set off ebay and have the dealer program for gen 2 fob? Or can you do it yourself using forscan? Is the key sensitive or can I just have one cut? Key is $10 on ebay, fob as well.. Just realized the Valet key when used on drivers side locks all doors and arms it seems? Reg one didnt do that..
