Keyboard exchange

Hi, I bought the Blackwidow v3 a month or two ago and I love every bit of it. However, Razer recently released a Halo-themed keyboard that is the same as the one I have now. My question is, am I able to simply exchange the one I have now for the Halo one, or am I screwed. I know there is a price difference so I have no problem paying a few extra bucks, I just need to know how to do it. Thanks, A
