Got a G6... No keys

I have an '07 G6 to fix up and sell but no keys for It. I have been searching for info but am coming up short. Does anyone know if the procedure to program a new PK3 key will work on an 07? If not, is there another or am I at my dealers mercy for key programing?

Well, basically you need proof of ownership, and the VIN #, and you can get a key cut at any GM dealership....

Then you need to create a "master" key, by using the 30 minute procedure(make sure you use a jumper box)......
