How to replace the spacebar button on a MacBook Pro?

Question

Do it yourself

Photo of a new button with a butterfly mechanism from the Internet, already ordered:

On my current one, I broke this very mechanism - when I opened it, the butterfly pins broke off.
Q: How to install this butterfly mechanism in general? That's why I broke it, that to install it back is another task if it popped up.

Answer 1

Everything is very simple. So that the pins do not break off, the button must be snapped off from the top from the corner and then move horizontally to the next corner. Then we remove 3 transparent plates (left, right and central with a metal membrane), they are put on glue or thin double-sided tape. After that, the mechanism quietly gets. Assembly in reverse order
