Locked out of iPad

Recovery mode If you forgot the passcode for your iPhone, iPad, or iPod touch, or your device is disabled - Apple Support

No I am no way a pro at this however I think you can hook it up to iTunes on your computer and do a reset that way. Now it may be a factory reset that would erase everything. Just like I said I am not pro at these things so I may be wrong. With these new Apple products I am not sure if they allow you to reset them that easy or not. I also know Apple is axing iTunes for something different so it may not work to reset the iPad using iTunes.

Good Luck
