BENQ Confusion with DVD key and CPU key

Hi, I have carried out an RGH on my xbox 360 a while back and everything is working fine apart from the DVD drive.

The CPU key and DVD key do not match. To fix this I tried to flash my DVD drive with the stock firmware and simply changed the key to the CPU key. This didn't work and I don't really understand what I should do?

I read that I need to reflash the NAND with the CPU key again but I'm unsure if this is correct/how this will fix it. If it is the DVD key that is the issue why does flashing the DVD drive not change it?

Thanks for any advice!
