Dell does not sell keyboard components -- you could look on Ebay for someone selling the same keyboard and low cost and salvage the part you need, but that's the only option you have short of replacing the keyboard.  
Hiya, I am missing the left CTRL key on my Alienware gaming keyboard.  I suspect cat activity as I have previously caught Andrew, my black cat, attempting to chew on my keyboard.  It was there last night and today when I went to play... gone.  I cant seem to find any spare keys on line and was wondering if anyone knew where i could source some?   I can't afford to buy a new keyboard as this was a gift the Christmas before last.  any help would be greatly appreciated.   This is Andrew. butter wouldn't melt.  [IMAGE]
