Introdução
This guide demonstrates how to quickly and safely replace the up arrow key on a 2019 Macbook Air. The instructions provided can also apply to any third generation butterfly keyboard on a MacBook.
The up arrow key is essential for navigation, and if that key is not working, the entire device can become unusable. An arrow key on a MacBook may need replacement if it is unusable due to being snapped off, is loose or sticky, or has debris stuck under it. A key that is unresponsive to being pressed most likely needs to be replaced. This guide provides a fast, cheap solution to getting your MacBook’s keyboard working properly.
