Place a guitar pick between the click wheel and the case of the Nano and remove the metal spudger.

Pry up the edges of the click wheel with the guitar pick until the click wheel comes free from the case.

Be extremely careful not to poke or puncture the battery itself, as this may cause the battery to combust.
