OnePlus India — my fingerprint sensor and home button are not working

Address:

400607

My one plus 2 phone finger print sensor and home button are not working for the past 2 months. Not able to restore the same. What should I do? I have tried rebooting number of times. Catch data also also was erased.
Please give me immediately, a workable solution.
I tried to delete old finger print from the settings to register another set of finger print, but it could not be deleted. I tried to add another finger print, but it is not responding and is showing locked. How to unlock this finger print sensor?
Please guide me quickly.
