Can’t reinstall MacOs because disk is locked (2nd hand MacBook)
So I got a second hand macbook pro. I tried to reinstall macos, but it says that its locked
People said that i should go to disk utility and unlock the locked disk there
But the locked disk wasn’t there
And even if its there, i don’t know the password too. And I can contact the owner anymore

I have the same problem, did you find a solution?

Replace the drive. Drive firmware passwords on macs as far as I know are not something you can bypass.

I'm curious what would happen if you clicked the ”View” menu there in the upper left corner of the Disk Utility windows (second screenshot)?
Then you should be able to ”Show All Devices" which will probably show you the ”volume structure” of the internal drive.
Try to select the top item in this structure and then click the ”Erase” button and format it using the APFS file system if installing High Sierra or later.
