How to unlock my MacBook
Good day. I lost my MacBook so I blocked it. After they returned it to me and took it and accidentally deleted it from the account. What should I do? How to unlock it now?

If you can access the computer, can you sign in? I understand it was delete from your account, but if you can sign back in, it will be added back.
If necessary, boot to the Recovery Volume (command - R on a restart). Run Disk Utility/First Aid. Reformat the drive using Disk Utility/Erase. Use Mac OS Extended (Journaled), then click the Option button and select GUID. Quit Disk Utility, then re-install the OS.
When you reboot, use Setup Assistant to restore your data.
