Opening the iPod can be challenging; don't get discouraged if it takes you a few tries to get the iPod to open.

Insert a plastic iPod opening tool in the seam between the white plastic front and metal back of the iPod. It helps to hold the iPod at top and bottom as shown and squeeze to help pop out the edge. Once you've inserted the tool, run it along the seam to free the five tabs holding the iPod together.
