Hi, Can you please elaborate on "locked out"? What exatly do you see on your screen?
Thank you for the reply.
The problem you're having is often due to the software in the Kindle locking up and it needing to be rebooted. To do this, simply press and hold the power button on the Kindle for 25 seconds, then release and wait a full minute for it to reboot. If this does not cure the issue, oftentimes the reset procedure needs to be repeated several times for it to force a reboot.
If you're still running into problems, then try plugging the Kindle into the charger for 15 minutes, then eject it and try the reboot a couple of more times.
This clears up the issues you're having 90% of the times, but in the rare case that it does not, the problem may go deeper than a software issue. If this is the case, please reply back how long you've had the Kindle for, and I will continue to assist you.

If it's still asking for a password- it's not child lock, it's either your Amazon password (the one you use when you log onto Amazon.com) or the Wi Fi password. Try those each (make sure you use capitals where capitals are).
PIN is different, please see below:
