Is my D520 Latitude Keyboard Dead?

Yesterday morning soda got spilled on my dell d520 latitude keyboard. I was not aware of this and then that night when I went to use the laptop some keys didn’t work (A, D, G, R, T, Y). I have popped the keys off carefully and have cleaned up as good as possible for those keys and the surrounding keys but no such luck. I have a inspiron 500m that is lying around with a good keyboard. Is there any way to make it work with the D520 and is there anything I can do short of buying a new keyboard?

Thanks in advance!
