Only Apple can fix the Touch ID sensor that is connected to your phone to make it function properly again. If the phone has been altered by an unauthorized party, they will not repair it.
If your hands are wet, oily, dirty, or moist, the fingerprint sensor might not work. If your fingerprint sensor is not working, your phone might not unlock. Wash your hands and dry it. Next, use the fingerprint to unlock your phone. office.com/setup
