Hey guys! I needed switch my return key and I did it almost with perfection: key cover (the black thing) and butterfly clip were great but them I found a transparent plastic piece that is glued on keyboard. I have 2 questions about this transparent piece. What is the name of this transparent piece? How should I glue it or use a double sided tape (I really appreciate if you could add a link as reference to glue so I can find something close in Brazil) ? My return key is working but doesn’t seem glued well. I have added a photo of transparent piece to help identify.
Given the risks and how hard it is to glue (the part is welded together) I would just replace the part Space Bar MacBook/MacBook Pro Space Grey (Type-P) You also might want to try letting Apple fix it for free! Keyboard Service Program for MacBook, MacBook Air, and MacBook Pro
