I see a place in Ohio, that sells *just* the blank ignition key with a built in GM transponder chip embedded within the head section for $ 13. If this is what your looking for, there business is "fobkeyless.com"
Each G8 came new with a flip and a non-flip (fixed) key. I just assumed you had both. You can aslo tell the dealer you don't want the key recall done. They might have you sign something. My dealer was just like "meh, whatever" and didn't mention it again.
