My Macbook Pro keyboard and USB keyboard will not work. However, the trackpad and USB mouse will work. Any help?

This is quite frustrating, since it randomly occured as I was browsing the web. It seemed to happen out of nowhere. I cannot login to my user account because I cannot type my password.

Any help will be appreciated.
