Hi and Welcome. My Name is ***** ***** I look forward to assisting you today with your question.
This usually happens if the firmware is glitched. First we can can soft-reset the Kindle and see if it works or not. Press and hold down (or slide) the Power button for 20 seconds and this will reset the Kindle. Then check if you are able to unlock it.
Please let me know if that didn't work, so we can continue troubleshooting.
