Overview
What this part is
The power and volume buttons on the OnePlus 9RT 5G press small switches on a thin flex cable inside the frame. The cable connects to the main board. Wear, a drop or liquid can break a switch or the cable, so a button stops working even when the outer key looks fine.
This part replaces the internal flex cable with its switches. It does not include the outer keys, which are reused. If a button still does not work with a new flex fitted, the connector on the main board may be damaged.

FAQ
Frequently asked questions
Will this fit my 9RT 5G?
Yes, if Settings › About phone shows OnePlus 9RT 5G. It does not fit the OnePlus 9R, OnePlus 9 or OnePlus 9 Pro.
Does it fit the OnePlus 9R?
No. The OnePlus 9R is a different phone and uses a different part. Check the model name in Settings › About phone before you order.
Does this include the outer buttons?
No. This is the internal flex cable with the switches. Your existing outer keys are reused.
Is it made by OnePlus?
No. It is a brand new, OEM-quality power and volume button flex cable made to fit the OnePlus 9RT 5G, and it is tested before dispatch.
Should I fit it myself?
We recommend professional installation. The 9RT 5G must be opened, the battery disconnected safely and the part handled carefully.
