Here I add to one more type of lock i.e. Double Cylinder- Double cylinder deadbolts are considered more secure because they require a key on both the inside and outside but also pose a safety hazard in the event of an emergency. Some housing codes in the United States do not allow for this form of the deadbolt, specifically on rental housing.
