Kind've surprised that this hasn't been mentioned yet, but Alienware has been giving away keys for the last hour or so.
NA and EU keys should all work as they aren't region locked. That is unless these keys are specifically made to be different for some reason.
Due to frequent travel in my youth, English isn't something I consider my primary language (and thus I obtained quirky ways of writing). German and French were always easier for me despite my family being U.S. citizens for over a century. Spanish I learned as a requirement in school, Japanese and Korean I acquired for my youthful desire of anime and gaming (and also work now). I only debate in English to help me work with it (and limit things). In addition, I'm not smart enough to remain fluent in everything and typically need exposure to get in the groove of things again if I haven't heard it in a while. If you understand Mandarin, I know a little, but it has actually been a challenge and could use some help.
Also, I thoroughly enjoy debates and have accounts on over a dozen sites for this. If you wish to engage in such, please put effort in a post and provide sources -- I will then do the same with what I already wrote (if I didn't) as well as with my responses to your own. Expanding my information on a subject makes my stance either change or strengthen the next time I speak of it or write a thesis. Allow me to thank you sincerely for your time.
