Left Joy-Con 2 Back Cover Removal

Use a tri‑point Y00 driver to remove the two 3.1 mm‑long black screws on the right edge of the controller.

Insert an opening pick into the gap underneath the bumper button on the left side of the controller, with a point of the pick pointing downwards.

Pry up to slightly lift the plastic strip running across the left edge of the controller.

Slide the opening pick around to the front of the controller.

Slide the opening pick down the plastic strip to separate the clips and adhesive securing it to the controller's body.

Pry up on the bottom edge of the plastic strip with slow, steady force.

Repeat this prying action along the length of the strip until it's fully detached.

Remove the plastic strip.

Remove the two screws on the left edge of the controller:

One 3.1 mm‑long tri‑point Y00 black screw

One 3.0 mm‑long JIS 00 silver screw

Insert an opening pick into the gap between the front and back halves of the controller on its left side.

Slide the pick down the controller to disengage the clips.

Leave the opening pick at the bottom of the controller's left edge, just before its curve.

Hold the controller upside-down.

Insert a point of another opening pick next to the release button at the top of the controller.

Use the opening pick to press the release button through the gap.

While holding the release button with the opening pick, use your other hand to slide the back cover down to release the clips securing it to the controller's body.

Open the back cover.

Firmly grasp the two wires (blue and white) above the rumble motor connector, located at the bottom of the controller's board, and pull the beige connector out of its socket.

Remove the back cover.
