Problème de lenteur de mon code VBA

Bonjour à tous,

J'ai un fichier avec un peu de code VBA pour automatiser une mise en forme.
Cependant je trouve le code très long.
Je sais que l'utilisation du .select alourdit toujours les procédures VBA mais je ne sais pas trop comment l'améliorer étant novice.
Pouvez-vous m’aiguiller sur une amélioration de mon code s'il vous plaît ?

le voici :

Dim range As range
Dim cell As range
Dim cb As CheckBox
Dim i As Integer
Dim MaPlage As range

Sub Boutonajoutligne()

ActiveSheet.Unprotect "mc16c"
ActiveCell.EntireRow.Insert Shift:=xlDown
ActiveCell.Offset(-1, 0).EntireRow.Copy Cells(ActiveCell.Row, 1)
On Error Resume Next
ActiveCell.EntireRow.SpecialCells(xlCellTypeConstants, xlNumbers + _
xlTextValues + _
xlLogical + _
xlErrors).ClearContents
Selection.Locked = False
ActiveSheet.Protect Password:="mc16c", DrawingObjects:=False, Contents:=True, Scenarios:= _
False, AllowFormattingCells:=True, AllowFormattingRows:=True, _
AllowInsertingRows:=True, AllowInsertingHyperlinks:=True, _
AllowDeletingRows:=True, AllowSorting:=True, AllowFiltering:=True, _
AllowUsingPivotTables:=True
Cells(ActiveCell.Row, 1).Select

End Sub
