Also known as a dead bolt, dead locks are a type of door locking mechanism which can only be opened and closed with the turning of a compatible key. Dead locks do not include a latch, meaning the door will not remain closed when unlocked. Suitable for both external and internal doors, dead locks are often installed as a secondary security measure for external doors to work in conjunction with a standard door knob or backplate lock.
