Flip the Chromebook back over and open the screen.

Wedge the plastic opening tool between the keyboard and the bottom of the Chromebook.

Run the plastic opening tool along the seam between the keyboard and the bottom of the Chromebook until the keyboard moves freely. Several tabs will pop out.

It is normal for the tabs to make a loud click when released. The corner tabs will be harder to release than the others and will make a louder click.
