Using the Jimmy or other metal tools during this step could scratch the aluminum chassis; however, it's the simplest way to perform this step. Follow the alternate instructions to avoid scratching the aluminum.

Insert a Jimmy into the gap between the bottom cover and the chassis.

Pry up the bottom cover to create a gap.

Alternatively, you can insert the point of a spudger into one of the plastic vent holes and pry up to create a gap big enough to insert an opening pick into.

Keep the Jimmy inserted under the bottom cover.
