I saw a recommendation in a report summary to remove all double cylinder deadbolts. Is this referring to the deadbolts that require a key from both sides of the door?

Double Cylinder Deadbolts use keyed cylinders on both sides of the door. These deadbolts are generally used on doors that are part glass so that if an intruder breaks the glass, the door can’t be unlocked with out a key. It is not recommended on most doors because it increases the danger of an occupant being trapped in case of a fire unless the key is left in the deadbolt.
