I think so, I'd clean the area and after having figured out were the PCB traces are supposed to route the three pins, solder some wires to redo the connections.
Electrically this usually works but it will not be the strongest in mechanical terms, looks like at least two PCB pads are gone so the connector will not be properly fixed and so it will be prone to break the connections again.
Better to change the connector with a panel mount type.
Hope this helps.

thanks for you reply. The the pads are definitely out.
Yes that is the kind of connector I was referring to and it seems to me you did the right connections there.
I don't know about Sk-5 specifically but be aware that old casios are notoriously lacking any kind of protection against reverse supply polarity.
Beside not working does the keyboard show any sign of life at all?
If the power LED does not light up at all there's the possibility that the problem could still be around the power supply rails.
