Use this guide to replace the Touch ID sensor/power button in your MacBook Air 13" 2022.
You may need to replace the Touch ID sensor/power button if it's unresponsive, inconsistent, or physically damaged.
To maintain Touch ID functionality, you must also replace your logic board with a new one that's paired to the replacement Touch ID sensor. The MacBook Air's original Touch ID sensor is uniquely paired to the logic board at the factory—and without Apple’s proprietary calibration process, even a genuine replacement logic board from another MacBook Pro won’t work.
Note: Replacing the Touch ID sensor required removing the logic board and right speaker.
