Locked Mac when trying to boot to update Hackintosh (help please, I'm desperate)

I can't update my Hackintosh because when I try to boot to the install macOS drive (for updating) it sends me to a screen that asks me to put in the 6 digit pin to unlock it from iCloud lock. This lock was set on the Mac months ago when I set it to prevent family members from snooping while I was away and didn't shut off my computer. Even then, I unlocked it fair and square after I got back. Now its asking me to unlock it again and when I put in the correct passcodes, it says it's wrong. I even locked it again with a new message and a new password (000000) to test it out and lo and behold, its "wrong". I can still boot into the normal Mac drive but its update part is locked.
