Overview
What this part is
The side keys are the outer power and volume buttons you press on the side of the Huawei Mate 20 Lite. A drop can crack, bend or knock out a button cap, leaving a gap in the frame or a button that will not press.
This part replaces the outer keys. It does not include the flex cable with the switches inside the phone. If the buttons are in place but do nothing when pressed, the inner flex is the more likely fault. Pick the colour that matches your phone.

Frequently asked questions
Will this fit my Mate 20 Lite?
Yes, if Settings › About phone shows Mate 20 Lite. It is made for models SNE-LX1, SNE-LX2 and SNE-LX3. It does not fit the Mate 20, Mate 20 Pro, Mate 10 Lite.
Does it fit the Mate 20?
No. The Mate 20 has a different frame and buttons. These keys are for the Mate 20 Lite only.
