Not as hard as it seems. First pry off the plastic cover on the back of the keyboard using a small blade. Inside you will see a small ribbon cable and a small screw holding it in place. Remove the screw and gently rotate the tube inside to get to the ribbon cable. Unclip the ribbon cable (a bit fiddly)and slide the plastic tube out of the opposite end of the keyboard to the batteries. You can then use a long screwdriver or similar to push the battery from the end of the battery compartment into the void left in the centre of the compartment. Clean any corrosion and re-assemble in the reverse order.
