I have a 2007 Silverado Classic LS. I have been trying to find a transponder key (ebay, Amazon etc). I already ordered and received 2 sets from different sources and both are the wrong blanks . I suspect I am getting the key for the newer style truck not the classic even though the questionaire for the key order specifically has the "2007 Classic model" listed. I avoided the dealer because I figured they were probably twice as expensive as on line. Anyone have any good sources

 

any locksmith?
