Since the keayboard side is superglued (who needs sustainability when you can just buy a new one, duh) it is impossible to access the electronics from the topside.

The PCB and Battery compartment on the backside is screwed from the inside which makes it virtually impossible to teardown.

However, the screws are, well.. screwed into thin little poles which can easily be broken with enough (not too much) leverage.

Begin with prying one corner with the thin prying tool.

Then slide a more sturdy wedge or in this case spatula underneath the first tool
