Do you need your Apple ID? If not that, what do you need to open the iPad?

See if you can recover the ID/password. An iCloud e-mail address is an Apple ID. Use every email address you can think of.

Other ways to find your Apple ID

You can check to see if you're signed in to the App Store, FaceTime, or Messages on your iPhone, iPad, iPod touch, or Mac, or check to see if you're signed in to iTunes for Windows on a PC. You can also go to iCloud.com or appleid.apple.com and see if your Apple ID prefills on the sign-in screen.   

If you forgot the Apple ID (iCloud) password, enter the Apple (iCloud) ID, and click Forgot Password. See if you can get a Rescue or Notification email option if necessary. Link to contact Apple Support at the end of the 2nd article.

Apple ID – Forgot Password  *      

Only you can unlock your device; assuming that's what you mean. Use the credentials you used to set up the device to unlock it.

I didn't mention updating the iPad. Why would you lock the iPad? What help do you need to open the iPad? More information would help.
