What you can safely check yourself

  1. Look at the gap. If the gap around the door is wider at the top on the handle side, the door has probably dropped.
  2. Test with the door open. Lift the handle and turn the key with the door open. If it moves freely, the lock is fine and the problem is alignment.
  3. Check the keeps. Shiny rub marks on one edge show where the hooks are catching.
  4. Do not force it. Forcing a stiff handle is the most common way a gearbox breaks.
