So I purchased a MacBook Pro from someone which seemed to work fine at first. But then I reformatted the drive so I could install a fresh copy of MacOS.
I noticed that every time I boot up now the lock icon shows up on the screen.
I did some research and found out it is a EFI / Firmware locked. I’m not sure exactly which one is the proper term or if both mean the same thing. Anyways, I have a spare MacBook Pro, same year, same kind of model and was wondering if i could just pull out the logic board from my spare system and put it into the system which is locked?
Would this eliminate my problem and have the ability to use my device? I really hope I can get an actual answer and not some sad person telling me its stolen and to give it back.

The best you can do here is contact the original owner for the password.
The firmware password prevents starting from any internal or external storage device other than the selected boot disk.
To protect data on your Mac, you can set a user account password (password to log in) to prevent other users from unauthorized access to your account. You can also encrypt a boot disk using FileVault so that only users who log on to a Mac can read data from this disk.
For even more reliable protection, you can set the firmware password. Users who do not know the password of the firmware will not be able to start the computer from any disk other than the one designated as the boot disk. Thus, it will be impossible to use some shortcut keys at startup.
