Can I lock my ipad with the use of my active apple id or serial number?
iPad mini, iOS 9
Yes. Follow the steps in the support document you posted from to set it to Lost mode (step 2 of the support document). That locks it with a passcode.
You use your Apple ID to log in to iCloud.com or on another device logged into your account to set it to Lost Mode.
