You could take the original key to Walmart and have them scan it to see if it is a transponder key or not. My 2010 did not have a transponder key, but I believe some did. Wiring the starter will be a treat...I gave up and went directly to the starter wire under the hood. I think in my Google searching I did find someone who figured out some combination of resisters and relays to make it work but I don't have the info saved.
