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:

For those who want to protect different range of cells you can edit the range in the code like what I did. Use "comma" if making multiple cells.

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

  Unlock the Worksheet, and when protecting again, enable the edit object checkbox before confirming passwords

  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
  End Sub

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

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!

  Good Day,
  At first, you need to set specified cells to Unlocked for editig, and then protect the worksheet. And finally apply the VBA script.

  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?

  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:

Private Sub Worksheet_Change(ByVal Target As Range)
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 :)
