Gently glide the iFixit opening tool on the top of the display, making sure to free the retaining clips.

The other sides of the iPod should now easily come loose. If they do not, use iFixit opening tools on the right side of the iPod in the same way as on the left side of the iPod.

Be sure to separate the front of the iPod from the back about an inch (or a couple of centimeters).
