Damaged usb keyboard cable

I have the chroma tournament v2 tenkeyless keyboard. Somehow the cable has been severed, it's a clean cut but I would imagine there are several wires in there. I'm no stranger to soldering irons and heat shrink but since these keyboards have all these delicious functions I'm going to take a wild guess that a soldered connection might affect the keyboard in negative ways. I'm certain no matter which option I choose there will be a bit of surgery here but is it smarter to order the whole cable or try to splice the damaged existing cable? Better yet, can razer fix it, it was a pretty expensive keyboard at least to me probably worth a fix as long as it's not nearly as much as a new keyboard.

Please advise. Thanks.
