k65 lux rgb Keyboard warranty Void?

im currently using a K65 Lux RGB Red switch, but i've open the keyboard before to clean the dust inside due to my previous smoking habit, a lot of ash stuck inside of the keyboard, what im trying to ask is i've removed the back sticker(serial number sticker) and recently my down arrow key rgb is different colour with other as i always use static in corsair link, will my warranty void cause i removed the sticker to clean the dust in the keyboard before? But i still kept my keyboard box( i keep all my pc boxes )??

Sadly, yes, yes it's voided. you might've left some dust on the SMD (surface mounted) LED or you could have damaged one of the RGB channels (e.g blue).
