how do I unlock my Advent 7101 Laptop keyboard?

This works for my 7011 - same series :

Remove the keyboard by releasing the 3 retractable clips at the front of the keyboard with a small screwdriver -
these should be below the 'Fn', the 'Alt Gr', and the 'Down Arrow' keys. When removing the keyboard be careful not to damage the strip cable at the back.
