What is the correct CodeName syntax?

[HURTMYPONY]

I have this bit of code:

    Dim LC As Long
With Sheets("SourceCloser")
    LC = .Cells(4, Columns.Count).End(xlToLeft).Column
    .Range("C5:C90").Copy Destination:=.Range(.Cells(5, 4), .Cells(5, LC))
    
    
End With

And I would like it to work with the SourceCloser sheet's CodeName (sheet13) instead of the sheet name.

What is the correct syntax? I tried a few variations, but none work...
