AW510K, key replacement

I also have the same problem my Alienware AW510K. Dell tech Support told me that it is not an ongoing issue with the keyboard and that my keyboard replacement is not covered. So I needed to purchase an accidental damage coverage in order for them to replace it I’ve only had it for 4 months and is still under warranty. But they keep telling me that that is not an internal issue with the keyboard. To purchase the coverage.
