Combining 2 vba codes over 2 different ranges into one statement - excel

Question

I can make one or the other of the below codes work, but need them both. The first locks cells in range upon data entry, the second inserts a date stamp when the final data entry in column D of each row is completed.
Private Sub Worksheet_Change(ByVal Target As Range)
Dim xRg As Range
On Error Resume Next
Set xRg = Intersect(Range("A8:D5005"), Target)
If xRg Is Nothing Then Exit Sub
Target.Worksheet.Unprotect Password:="Midnight"
xRg.Locked = True
Target.Worksheet.Protect Password:="Midnight"
End Sub
Private Sub Worksheet_Change(ByVal Target As Range)
Dim rng As Range
Set rng = Range("D8:D5005")
If Not Intersect(Target, rng) Is Nothing Then
Target.Offset(0, 1) = Now
Target.Offset.NumberFormat = "dd/mm/yyyy hh:mm:ss"
End If
End Sub

I'm still guessing a bit exactly what you're trying to do … but here is way to allow your users enter four data points ... and then to press button to add the data points to a protected list … and includes a time stamp.
First setup 4 data entry cells in A4 through to D4 by using the Format Cell option, make sure for these cells that Locked is unchecked on the Protection tab.
Next create a button and link the button to the following code:
Sub ButtonCode()
ActiveSheet.Unprotect Password:="A"
Range("A7:E7").Insert xlShiftDown
Range("A4:D4").Copy Range("A7:D7")
Range("E7") = Now()
Range("A7:E7").Interior.Color = rgbLightBlue
Range("A7:E7").Font.Color = rgbBlack
ActiveSheet.Protect Password:="A"
End Sub
As a once only step, protect the worksheet; my example consistently uses a password of "A". Note that your users will not need to enter the password at any time.
Once the sheet is setup, when the button is clicked, the code unlocks the sheet (allowing it to make edits), it move the existing data data down, copy the new data points to the top of the list, adds timestamp and some minimal formatting. It then re-enables protection so that the user can't overwrite the existing entries.
The screenshot below gives you an idea of what it might look like, including showing that A4:D4 need to be unlocked.
Maybe not the implementation direction you were thinking of … but the principles included in this example might work for you. All the best.

I'm not 100% sure of the structure of your worksheet, so here are the assumptions for my response. You only want the user to modify cells in the range "A8:D5005" … and somewhere on the sheet you want to record date/timestamp changes for cells changed.
So I would start by protecting the sheet by going to the Excel "Review" ribbon (not in VBA), and setting up an editable range as follows.
Before you close the dialog box, click on Protect Sheet so that the rest of the sheet is password protected.
Once you've done this … you can use something like the code below to record the date/timestamps. In this example … I record them in columns to the right of your editable range (given your editable data is only to Column D).
Private Sub Worksheet_Change(ByVal Target As Range)
Dim vIntersect As Variant
Set vIntersect = Application.Intersect(Target, Range("A8:D5005"))
If Not vIntersect Is Nothing Then
Application.EnableEvents = False
Target.Worksheet.Unprotect Password:="Midnight"
Target.Offset(0, 5) = Now
Target.Offset(0, 5).NumberFormat = "dd/mm/yyyy hh:mm:ss"
Target.Worksheet.Protect Password:="Midnight"
Application.EnableEvents = True
End If
End Sub
