Lock or protect cells after data entry or input with VBA code

For example, the certain range of blank cells is A1:F8. Please do as follows to lock these cells after data entry in Excel.

1. Please unlock this range first, select the cells and right-clicking, then choose Format Cells in the right-clicking menu, and in the Format Cells dialog box, unchecking the Locked box under the protection tab, and finally clicking the OK button. See screenshot:

2. Click Review > Protect Sheet. And specify a password to protect this worksheet.

3. Right click the sheet tab, select View Code from the right-clicking menu. Then copy and paste the below VBA code into the Code window. See screenshot:

VBA code: Lock or protect cells after data entry or input

Dim mRg As Range
Dim mStr As String

Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)
If Not Intersect(Range("A1:F8"), Target) Is Nothing Then
    Set mRg = Target.Item(1)
    mStr = mRg.Value
End If
End Sub
Private Sub Worksheet_Change(ByVal Target As Range)
    Dim xRg As Range
    On Error Resume Next
    Set xRg = Intersect(Range("A1:F8"), Target)
    If xRg Is Nothing Then Exit Sub
    Target.Worksheet.Unprotect Password:="123"
    If xRg.Value <> mStr Then xRg.Locked = True
    Target.Worksheet.Protect Password:="123" 
End Sub
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Not Intersect(Range("A1:F8"), Target) Is Nothing Then
    Set mRg = Target.Item(1)
     mStr = mRg.Value
End If
End Sub

Note: In the code, “A1:F8” is the range you need to input data; and “123” is the password of this protected worksheet. Please change them as you need.

4. Press Alt + Q keys simultaneously to close the Microsoft Visual Basic for Applications window.

After finishing entering data to the cells of range A1:F8, they will be locked automatically. And you will get a prompt dialog box if you try to change any cell content of this range. See screenshot:

    After implementing this code, I can no longer sign my signature in Excel's signature tool. What code can I add so that this won't occur? I can set it so that one can edit objects but as soon as I type something into one of my protected cells the options are reset and I can't use the signature box. Any help would be appreciated

      Hi,
      If there are merged cells in the specified range, please try the following code.

      Dim mRg As Range
      Dim mStr As String

      Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)
      If Not Intersect(Range("A1:F8"), Target) Is Nothing Then
      Set mRg = Target.Item(1)
      mStr = mRg.Value
      End If
      End Sub
      Private Sub Worksheet_Change(ByVal Target As Range)
      Dim xRg As Range
      On Error Resume Next
      Set xRg = Intersect(Range("A1:F8"), Target)
      If xRg Is Nothing Then Exit Sub
      Target.Worksheet.Unprotect Password:="123"
      If xRg.Value <> mStr Then xRg.MergeArea.Locked = True
      Target.Worksheet.Protect Password:="123"
      End Sub
      Private Sub Worksheet_SelectionChange(ByVal Target As Range)
      If Not Intersect(Range("A1:F8"), Target) Is Nothing Then
      Set mRg = Target.Item(1)
      mStr = mRg.Value
      End If

    Hello, I'm trying to code so that a user can double-click and it will capture their username and timestamp. I was the cells to lock immediately after this is completed. I have the following in VBA, but it keeps debugging back to the "Target = Environ("USERNAME") & " " & Now()". I am VERY new and VERY inexperienced w/ VBA, so please bear with me if it's something small I'm doing wrong.

    Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)

    Target = Environ("USERNAME") & " " & Now()
    Cancel = True

    End Sub

    Private Sub Worksheet_Change(ByVal Target As Range)
    Dim xRg As Range
    On Error Resume Next
    Set xRg = Intersect(Range("A1:D45"), Target)
    If xRg Is Nothing Then Exit Sub
    Target.Worksheet.Unprotect Password:="GENERAL"
    xRg.Locked = True
    Target.Worksheet.Protect Password:="GENERAL"
    End Sub

      Hi Jess,
      The below VBA code can help you.
      Note: When protecting the worksheet, please uncheck the "Select locked cells" option in the Protect sheet dialog box. Thank you for your comment.

      Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)
      Dim xRg As Range
      On Error Resume Next
      If ProtectContents Then
      Set xRg = Intersect(Range("A1:D4"), Target)
      If xRg Is Nothing Then Exit Sub
      Target.Worksheet.Unprotect Password:="123"
      Target = Environ("USERNAME") & " " & Now()
      Target.Locked = True
      Target.Worksheet.Protect Password:="123"
      Cancel = True

    hello there need some help


    im actually doing a working roster for a large group of people, and this sheet is accessible by all so that they can key in their requests for days off/ annual leaves etc. however i want to only limit a number of people on leave for each day (maximum 5 on leave) and after 5 leave requests are keyed in for the day, no body else can fill anymore requests for that particular date.


    is there any code/function that will calculate the number of specific requests perday then when the quota is reached, then the other cells are blocked for the requests as to not exceed? thanks in advance

    Hello,
    Is there a way to lock only cells rather than the whole sheet? For example, if a user enters "Yes" in A2, then A2 would lock immediately as to not allow any changes. I would still like if others could still edit any other cell too. Thanks!

    Hi
    editing the code is there a way i can get it to lock all the cells in the range after data has been entered into one cell within that range ? so they can only enter data into one cell within the range not multiple.

    • To post as a guest, your comment is unpublished.
      crystal · 2 years ago
      Dear Subhash,
      After using the code, only the edited cells are locked in the specified range. And you can still enter data into the empty cells in the specified range as you need. After fill in the blank cell, it will be locked automatically.

    For anyone who might have stumbled here since this comment.
    If you are having to unlock the worksheet EVERYTIME you fill in a cell then you need to first,

    - Unlock the spreadsheet
    - Highlight the area of the worksheet the code applies over
    - Right-click and go to 'format cells'
    - Go to the far right tab called 'Protection' and UNCHECK the 'Locked' section (Even if It appears as a solid fill instead of a tick)

    After that you will be able to enter data in multiple cells without having to unlock everytime. Bear in mind if you need to revisit locked cells to delete or edit information you may need to repeat the steps above.

    Hope this helps.

    I tried the code and seemed to work somewhat. It does however allow me to delete the date entered into the cell but only stops me when I try to enter something else. Is there a way to keep data from being deleted?
    • To post as a guest, your comment is unpublished.
      crystal · 2 years ago
      Dear Stacy,
      The same problem does not appear in my case. The code prevent users from entering as well as deleting data from the specified range. Would you provide your Office version for further testing?

    Try this code instead:

    Dim MyRange As Range

    Set MyRange = Intersect(Range("A1:D100"), Target)
    If Not MyRange Is Nothing Then
    Sheets("Sheet1").Unprotect password:="hello"
    MyRange.Locked = True
    Sheets("Sheet1").Protect password:="hello"
    End If
    End Sub


    And remember to change range (A1:D100), password (hello) and sheet (Sheet1) names/numbers if it does not match the above :)
