The small lug that holds the button's hinge pin is clearly visible in the circled area, and the other half of the pair is pointed to by the arrow.

The video demonstrates how to insert the blade of a knife carefully behind the lug and push it in far enough for the pin to clear the lug.

Once the key is freed from the left side mechanism, it is still connected on the right side.

Release the key by rotating it counterclockwise with a tool or your fingers.

Unclip the lever arm by carefully inserting a spatula or a knife (be careful, the metal can damage the fingerboard).

Detach the white part of the key. Take this opportunity to clean any dust or debris from the key or the hinge mechanism.

Insert the hinge (framed in the photo) into the metal slot in the keyboard as shown in the second photo.

The third photo shows the hinge mechanism properly in place.

The final step is to place the key on the hinge mechanism and press hard on it so that the key clicks into place; the sound of the clips locking will be perceptible. There are four clips holding the key cap.
