2010 cts Posted September 30, 2011 Report Share Posted September 30, 2011 just purchased a 2010 CTS sport wagon and love it. i believe that my #1 smart key fob needs reprogrammed. i checked the battery and it is good. the procedures in the manual tell me thru the DIC that the key is recognized but none of the buttons work. the # 2 fob works perfectly(complete with remote start) . i believe that i need to reprogram or relearn the key fob. i have read and downloaded some instructions posted and i think i need a scanner. is that as in OBD II scanner? any help would be appreciated.
