First check if your worksheet is protected, if yes then try below code:
ThisWorkbook.Worksheets("Sheet2").Unprotect Password:="Password"
ThisWorkbook.Worksheets("Sheet2").Cells.Locked = False
ThisWorkbook.Worksheets("Sheet2").Range("B8:C9,B5:C6,D1:R1,Q4:R4,A12:S17,A19:S33").Locked = True
ThisWorkbook.Worksheets("Sheets2").Protect Password:="Password", UserInterFaceOnly:=True   'DrawingObjects:=True, Contents:=True, Scenarios:=True

Open in new window

Change the password.
