Sorry if dumb question, searched and found no definitive answer. I just got a 2014 Rubicon to replace the 2008 Sahara and want to be sure I have multiple keys. 2008 on ebay there are 600 or more choices for keys, 2014 very few and more dollars. Some say they interchange, some not. Anyone know for sure . All the fobs listed for wrangler 2008 look the same as the new 2014.
