I tried targeted disc mode and then my other imac wont start. It only shows a picture of a lock with a password box. I tried all my codes but it will not open or start up. It does not open utility like it should so I cannot boot from the internet or other media. Please help.
iMac 21.5″ 4K, macOS 12.2

This is Firmware Lock, or EFI Lock. You cannot do anything until you get this password that it is prompting you for.

Rephrased, the utility won' load so I cannot do any of the commands in start up. It sees the bios at first because it shows the apple. There is no progress line at this time then it stops and shows the lock symbol.
I tried all the start up commands and it does not see those because the utility wont load. I tried several keyboards and another mouse but no change, it just wont load the recovery utility.
There is currently another forum running parallel to this on the fake internet here, it changed my post and so i fixed it but this might happen again.
Actually, it was the same one I tried targeted disc mode on that will not start not the other one. I got three of them.
imac wont start after targeted disc mode
