Completely power off and unplug your MacBook Pro before you start. Close the screen and flip the entire laptop upside-down.
Use a P5 Pentalobe driver to remove eight screws securing the lower case:
Four 9.3 mm screws
Four 5 mm screws
Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your device.

Sliding clips along the back edge of the MacBook further secure the lower case. Separating these clips may require a lot of force—consider using gloves to protect your hands from the sharp edges of the lower case.
Firmly pull the lower case away from the back edge, one corner at a time, to disengage the sliding clips.
Keep the lower case flat to the MacBook. Don't pull upward until it's completely separated.

Remove the lower case.
To reinstall the lower case:
Lay it down and align the sliding clips with the back edge of the MacBook. Press down on the lower case and slide it toward the back edge to engage the clips.
When one side is engaged, it may push the other out of alignment. Check both sides as you push.
Once the back corners of the lower case are secured and flush with the frame, press down along the middle of the lower case to engage the four remaining clips.
You'll hear and feel each clip snap into place.
