Hey guys, need help on another Chevy vehicle issue. I'm asking on the Tahoe forum because I get no response on the Chevy Equinox Forum. I bought my wife a 2007 Chevy Equinox Lt. It came with 1 key and 1 fob. I bought a replacement key and fob on line. I was able to program the fob and get the key cut but the key has a transponder and wont start. I have tried many online programming but none have worked. The Vin starts with (2CNDL). Can anyone help me with programming or is this a locksmith or dealership issue.
