Use this guide to replace the Touch ID sensor/power button in an Early 2020 MacBook Air.
Note that Touch ID will not function after replacing the Touch ID sensor. The MacBook’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 Touch ID sensor from another MacBook Air won’t work.
If you replace the Touch ID sensor, you must install a paired logic board to retain Touch ID functionality.
