First...........select all cells on sheet and format them to unlocked.

Add this event code to the worksheet module.

Private Sub Worksheet_Change(ByVal Target As Excel.Range)
On Error GoTo enditall
Application.EnableEvents = False
If Target.Cells.Column = 3 Then
ActiveSheet.Unprotect Password:="justme"
n = Target.Row
If Me.Range("C" & n).Value < "" Then
Me.Range("C" & n).Locked = True
End If
End If
enditall:
ActiveSheet.Protect Password:="justme"
Application.EnableEvents = True
End Sub

When you enter a value in column C that cell will become locked for
editing.
