Hi, I want to be able to lock cells f3 and G3 after a date and time specified in c3 (date) and d3(time). Is this possible without vba , or if not could somebody assist with the vba?
Thanks in advance.

Don't know if there is a non-VBA solution. You can try this VBA if you want. Format columns C and D as text. Paste the code into the "ThisWorkbook" module.
VBA Code: 
Private Sub Workbook_Open()
    Dim dateNow As String
    Dim timeNow As String
    Dim wbPw As String
    
    dateNow = Format(Now, "dd-mm-yyyy") '<------ Change to the format you want here
    timeNow = Format(Now, "hh:mm:ss") '<------ Change to the format you want here
    wbPw = "pw" '<--------- Change the sheet protection password here
    
    If TimeValue(timeNow) > TimeValue([D3]) And DateValue(dateNow) >= DateValue([C3]) Then
        With ThisWorkbook.ActiveSheet
            .Unprotect Password:=wbPw
            .Range("F3:G3").Locked = True
            .Protect Password:=wbPw
        End With
        ThisWorkbook.Save
    End If
End Sub

Thanks very much, I will try this! Could this be altered to apply to the next row down and so on ? Really appreciate your help.

Test this out. Made it so you can adjust the rows and columns, and fixed a mistake that made it not lock if the date was due but not the time :P
VBA Code: 
Private Sub Workbook_Open()
    On Error GoTo ErrorHandler:
    Dim dateNow As String
    Dim timeNow As String
    Dim wbPw As String
    
    rStart = 3 '<------- You can change start/end row, columns to lock, and columns for time/date here
    rEnd = 40
    colDate = "C"
    colTime = "D"
    colLock1 = "F"
    colLock2 = "G"
    
    dateNow = Format(Now, "dd-mm-yyyy") '<------ Change to the format you want here
    timeNow = Format(Now, "hh:mm:ss") '<------ Change to the format you want here
    wbPw = "pw" '<--------- Change the sheet protection password here
    
    With ThisWorkbook.ActiveSheet
            .Unprotect Password:=wbPw
            For i = rStart To rEnd
            If Evaluate(colTime & i) = "" Or Evaluate(colDate & i) = "" Then GoTo NextIteration
            If (TimeValue(timeNow) > TimeValue(Evaluate(colTime & i)) And DateValue(dateNow) = DateValue(Evaluate(colDate & i))) Or DateValue(dateNow) > DateValue(Evaluate(colDate & i)) Then
                .Range(colLock1 & i).Locked = True
                .Range(colLock2 & i).Locked = True
                Else
                .Range(colLock1 & i).Locked = False
                .Range(colLock2 & i).Locked = False
            End If
NextIteration:
        Next
        .Protect Password:=wbPw
    End With
    ThisWorkbook.Save
    
    Exit Sub
ErrorHandler:
    MsgBox ("Something went wrong when locking cells based on time and date")
End Sub

I noticed an error, dates are tricky but this should be working.... test thoroughly :D Also added a variable for the sheet, in case you have multiple in your workbook (this will only work on one of them as it is set up now).

VBA Code: 
Private Sub Workbook_Open()
    On Error GoTo ErrorHandler:
    Dim dateNow As String
    Dim timeNow As String
    Dim wbPw As String
    Dim sheetToLock As Worksheet
    
    Set sheetToLock = ThisWorkbook.Worksheets(1) '<------ Change number or sheet name ThisWorkbook.Worksheets("sheet name") to change which worksheet is affected
    rStart = 3 '<------- You can change start/end row, columns to lock, and columns for time/date here
    rEnd = 40
    colDate = "C"
    colTime = "D"
    colLock1 = "F"
    colLock2 = "G"
    
    dateFormat = "dd-mm-yyyy" '<------ Change to the format you want here
    dateNow = Format(Now, dateFormat)
    timeNow = Format(Now, "hh:mm:ss") '<------ Change to the format you want here
    wbPw = "pw" '<--------- Change the sheet protection password here
    
    dayNow = Day(dateNow)
    monthNow = Month(dateNow)
    yearNow = Year(dateNow)
    
    With sheetToLock
            .Unprotect Password:=wbPw
            For i = rStart To rEnd
            If .Range(colTime & i) = "" Or .Range(colDate & i) = "" Then GoTo NextIteration
            dayThen = Day(Format(DateValue(.Range(colDate & i)), dateFormat))
            monthThen = Month(Format(DateValue(.Range(colDate & i)), dateFormat))
            yearThen = Year(Format(DateValue(.Range(colDate & i)), dateFormat))
            
            Dim timeAndDateDue As Boolean
            timeAndDateDue = False
            
            If yearNow < yearThen Then
                timeAndDateDue = False
            ElseIf yearNow > yearThen Then
                timeAndDateDue = True
            Else
                If monthNow < monthThen Then
                    timeAndDateDue = False
                ElseIf monthNow > monthThen Then
                    timeAndDateDue = True
                Else
                    If dayNow < dayThen Then
                        timeAndDateDue = False
                    ElseIf dayNow > dayThen Then
                        timeAndDateDue = True
                    Else
                        timeAndDateDue = timeNow > TimeValue(.Range(colTime & i))
                    End If

Just had a friend testing this and he says it locks on opening but leaving it open allows you to edit previous rows f and g.
