Excel: Protect Cell After Data Entry

I have a spreadsheet with columns B and L. For any entry in columns B or L, I would like the cell to be protected as soon as input complete.

So, if a value is entered into B2, it should be protected. But when the user moves to B3, that cell should be still open for input while B2 is locked.

Can someone help?

In the sheet module

Option Explicit

Dim blnUnlockedAllCells As Boolean
Private Sub Worksheet_Change(ByVal Target As Range)
    
    Const RangeToLock As String = "B:B,L:L" '<<  adjust to suit
    
    If Target.Cells.Count > 1 Then Exit Sub
    
    If Not blnUnlockedAllCells Then
        Me.Cells.Locked = False
        On Error Resume Next
        Me.Range(CStr(RangeToLock)).SpecialCells(2).Locked = True
        On Error GoTo 0
        blnUnlockedAllCells = True
        Me.Protect Password:="pwd", userinterfaceonly:=True
    End If
    
    If Not Application.Intersect(Target, Me.Range(CStr(RangeToLock))) Is Nothing Then
        If Len(Target) Then Target.Locked = True
    End If
    
End Sub

Using Worksheet Change Event is good in some cases but the downside is that you lose your Undo History.

So in this case, what happens if the users realises that they have entered the wrong value in B2? The Change Event locks it and they can't change it. They can't just do an Undo either because a macro has run.

Thanks very much. I see where the sheet module example given could work well for me.

Question: how best to combine two different subroutines on the same sheet module? I have another in place now, which I use to control point of focus. How best to combine the below with the proposed solution?

Private Sub Worksheet_Change(ByVal Target As Range)
    If Target.Cells.Count = 1 Then
        Application.EnableEvents = False
        If Target.Column = 1 Then
            Target.Offset(0, 1).Value = VBA.Now
            Target.Offset(0, 10).Select
        ElseIf Target.Column = 11 Then
            Target.Offset(1, -10).Select
        End If
        Application.EnableEvents = True
    End If
End Sub
