Can I add another Else to this intersect?

How do I add to this code to say if row F says B then lock rows G and H?

I managed to do it earlier but caused another problem so had to start again. I seem to get close but can't get it correct!

Private Sub Worksheet_Change(ByVal Target As Range)

'Cell with A/B in it
If Not Intersect(Target, Columns("F:F")) Is Nothing Then
    'Unprotect sheet
    ActiveSheet.Unprotect "peoplepoint"
    'If A
    If UCase(Target) = "A" Then
        'Lock cell
        With Range("K" & Target.Row & ":P" & Target.Row)
            .Locked = True
            .Interior.Color = RGB(192, 192, 192)
        End With
    Else
        'Unlock cell
        With Range("K" & Target.Row & ":P" & Target.Row)
            .Locked = False
            .Interior.Color = RGB(255, 255, 255)
        End With
    End If
    'Re protect sheet
    ActiveSheet.Protect "peoplepoint"
End If
End Sub
