A deadbolt is often used to complement a spring-bolt lock on an entry door to a building.
A variant of the standard deadbolt is the vertical deadbolt, invented by Samuel Segal. Vertical deadbolts resist jimmying, in which an intruder inserts a pry bar between the door and the jamb and attempts to pry the bolt out of the door.
• Single Cylinder with removable thumb-turn
• Classroom Function (thumb-turn only unlocks door)
• Exit Only Function (no external cylinder)
• Push-button Deadbolt (mechanical or electrical)
The risk can be mitigated by locking the deadlock only when there are no occupants inside the building, or leaving the key near the keyhole. Some fire departments suggest putting the key on a small nail or screw near the door at floor level, since the cleanest air is at floor level and you may be crawling to get to the exit, thus placing the key where it is easiest to find.
