Demob’s Top Tips: Tight or Dirty Locks

If a lock seems exceptionally tight or dirty, it may help to lubricate the lock. NEVER use a liquid type lubrication such as WD40, 3-in-1 oil, etc… Use powdered graphite, available in most hardware stores. It comes in a little tube, allowing a light squeeze to blow a puff of graphite into the keyway and allow the cylinder to turn more easily.
