| Get extra security with a deadbolt |
| A deadbolt lock cannot be moved to the open position from the outside except by rotating the lock cylinder with the key. A deadbolt can be either single cylinder or double cylinder. A single cylinder deadlock has a key cylinder on one side of the lock, but is operated by a thumbturn on the other side. Double cylinder locks have a key cylinder on both sides. This prevents unwanted unlocking of the door by forced access to the interior thumbturn (via a nearby window, for example). Double cylinder locks are not recommended for residential applications because they violate fire safety regulations.
