Hey Lee,
Unfortunately the answer is no, there’s no kit that will restore Touch ID functionality once the home button or its cable get damaged. Your options are:
# Replace the button yourself—it’s a fairly easy job, but Touch ID will be permanently disabled. It will work only as a home button.
# Pay Apple for a screen replacement—more expensive, but they’ll include a new button and they can restore Touch ID.
# Find a repair shop with a professional microsoldering rig and the skills to [https://blog.rewatechnology.com/restore-iphone-touch-id-with-home-button-flex-replacing/|patch your home button cable back together|new_window=true].
Hope this helps!
