Son forgot iPhone passcode

Hi Scotty.  My son changed his password and is locked out of his phone (serves him right!).  How do I unlock it?!

You may be out of luck. The only way to resolve this would be to restore the phone. And even then, if you/he have enabled “find my phone” within his iCloud settings, the phone would be unable to be restored. This is a security measure to deter theft. A bad guy steals your phone, wants to erase it so he can sell it, the “find my phone” feature must be turned off first therefore requiring the thief to also know the iCloud password making the phone useless.
