how to program a replacement key on a 2005 cts with export theft deterrent
Turn the key in the ignition. Leave it on for about 10 minutes. If that doesn't work, leave it on for another half an hour. Make sure you have a fully charged battery before you do this. I switched ignitions on my Dodge Ram truck and that is what I did. The new key programs itself to the computer. It worked for me. Maybe it will work for you. Good Luck.
