Packard Bell MV35-202 Keyboard Removal

Hi, have drawn the short straw again. Friend of mine’s 3 year old son
managed to spill fizzy drink over the keyboard. The laptop works fine still
(Lucky..) but 5 keys are sticky/not working. So I found myself being dumped
with sorting it out.
I have searched high and low for a disassembly guide so that I can remove
the keyboard but without success. Is there anybody with experience of
keyboard removal on this make and model willing to advise me on exactly how
to safely and without causing further damage remove the keyboard so that I
can clean up the remaining mess ?
TIA for any help offered
