Disable selection on open?!

[jameztown]

I have a timesheet that consists of several locked and unlocked cells. Upon open, I have selections disabled until a button is clicked. Everything works perfectly except one issue. Upon opening, I also want one merged cell to be unlocked (B52:G53). Can this function be added to this?:

Private Sub Workbook_Open()

    With Sheets("TIMECARD")
        .Protect "password"
        .EnableSelection = xlNoSelection
    End With
     
    With Application
         'disable the ESC key
        .EnableCancelKey = xlDisabled
        .ScreenUpdating = False
         
        Call UnhideSheets
         
        .ScreenUpdating = True
         're-enable ESC key
        .EnableCancelKey = xlInterrupt
    End With
     
End Sub

Thanks very much for your feedback!
