You have a pin lock on your screen. Maybe someone played with it, you did it accidentally, or there was some glitch.

Try the usual 1234, 0000 or your regular favourite pin (unlikely I know).

If you are still out, try locating with Android Device Manager on a pc or other device, then use ADM's Lock option to set a new lock and new pin of your choosing which will override your current pin.
