Should I add a double sided dead bolt (key on both sides) on the exterior doors of my property, is it safe?
Double sided deadbolts are used on doors that have glass less then 18 inches from the lock. If someone breaks the glass they will not be able to unlock the door and leave with your possessions so easily. Fire code on rental properties, states that double sided deadbolts are not permitted. In a private property you should check with local laws and use your own discretion.
