Should a CPO come with a second key?

I'm not seeing anything about a second key in the CPO checklist, but just having the one key really shoe horns the user presets on the car. Is this something I should make a stink about or just bite the bullet and order a second key out of pocket? Just seems off that a CPO would come with everything else near brand new, but not the keys. Salesman is saying it came with just the one so tough luck.
