I think your best bet is to follow the guide to remove the top case. It appears to me that the procedure exposes the back of the keyboard and should allow cleaning to possibly restore full function to your keyboard. While you have it apart please do a complete cleaning of all the parts of the computer. Be advised the author of the guide list this procedure as VERY DIFFICULT. If cleaning fails you may need to replace the top case. Good luck.
