How long do I boil or steam frozen king crab legs?

I saw acouple threads already that kind of address this question. But the last time I cooked frozen crab legs, I steamed it for like 15 minutes. It was still a little cool inside. Am I cooking them wrong or for too short a period of time? Or should I let them thaw first?

They just have to be warmed through. They are already cooked so steam them longer to get them hot.
