touch id and home button not working

We can't diagnose that issue remotely, sorry.

Have you device inspected making an appointment at an Apple Store or Authorized Service Provider.

After checking it out, they'll give you all the available options: Apple – Location Selector

Make a genius bar appointment with Apple for an evaluation.

They have diagnostic tools and can tell you what options you have.

Take it to Apple for repair.
