Apple Imac A1314 Wireless Keyboard For parts - Left side keys not working


Several keys on the left side are not working: a-d, z-v and some others. A few keys on the right seem to make 2 different characters appear when pressed. 

I know I will only make it worse if I try and take it apart so this would be good for someone looking to replace grimey keys as they are in great shape. Or try your hand at fixing the underlying issue. 

Please see photos for overall condition and model number.
