Keyboard not functioning

I cannot type my password to get into my computer! I have to keep rebooting it. And then it will only take it once... sometimes the finger works, but, like the keyboard (of which it is a part) does not work either. It makes it VERY difficult to maneuver online without a functioning keyboard! It is NOT OLD. Can it be diagnosed? Reset? Whatever?

It IS connected/paired. Its battery is FULL. Bluetooth is on. It's the keyboard itself.
