Just bought a 2018 Denali with only 13k miles on it. Beautiful vehicle. One minor problem is, there is only one keyfob. I am searching for a replacement and do not have any desire to pay dealer price. There are several listings on Ebay but I do not know which one to get. I guess the first question I need to ask, is where do I get informationon the keyfob? I am going to ask the salesman to contact the previous owner to see if they happen tp know where the other keyfob went to.
