Its not that the machine will not cut them, it will if they have the correct cartridge. The issue is that no one but the dealer stocks the chipped blanks, so the keys wouldn't start the car even if they could cut them. It might be possible to find some retail place who has non chipped keys to cut, but all they can be used for is opening the door. I actually did this on my 06 dodge 3/4 ton. I cut a non chipped key, placed it in a hide a key under the bed rail so I could open the door if I locked the keys in it. But if someone found the hide a key, they couldn't start the truck with it.
