Just got a Razer blackwidow elite and i noticed the num pad 9 key didnt work, but i went onto keyboard tester and it did show that i clicked the key but wouldnt type. So i downloaded key tweak and just made the key 9 the same for the num pad 9 key, so its just mirroring it so it works. But now the numpad 9 key works and the 9 key doesnt if i reset the keys to default. So long story short all the keys work just seems like it doesn't want to be the key its supposed to be. Sorry if this makes no sense i contacted razer and they dont even know and i dont feel like returning the keyboard but i have month before im unable to so if i can fix it that'll be nice.
