With double-sided deadbolts, intruders can’t operate locks if they reach inside, even if they get their hand through a broken window. Double-sided deadbolts are used frequently on business doors and home front doors near a glass entry, as burglars often break a window and reach inside to unlock a lock. This is the reason double-sided deadbolts cost more than single-sided deadbolts, because there are actually two separate lock cylinders instead of just one.ĭouble-sided deadbolts often pose fire-related concerns for those who are seeking to exit a burning building but can’t because they don’t have keys to unlock the door from the inside-out. Many think that double-sided deadbolts are just one lock, but it’s actually two separate locks that are fitted on both the inside and the outside, instead of a flip turn on the inside. Double-sided deadbolts are different than single cylinder deadbolts because instead of being able to be locked or unlocked from the inside with a thumb-turn device, they must be operated with keys from either side. Double-sided deadbolts are actually two separate locks, but they are often installed on businesses and homes where locks are near windows. Single-cylinder deadbolts have a lock on the outside of the door with a keyhole for operation, and a flip turn on the inside for locking and unlocking. Deadbolt locks are separate from doorknob locks, and often come in either single cylinder or double cylinder variants. Deadbolts often offer superior levels of protection over their doorknob and lever counterparts of equal security rating.
