I am trying to register my BlackWidow Elite Keyboard's Warranty but, says the serial number invalid.


I have tried IO and io, neither have worked. What can I do?

I have the same/similar problem. Trying to register new Blackwidow keyboard and get "serial number is not known". First character looks like either upper case i or lowercase L e.g. I or l neither work.

try uppercase i then uppercase o as the first two characters of your serial number. I had same problem, thinking the second character was a zero, it weasn't. Best of luck
