Single-cylinder Deadbolt
-
The most common type of door lock, single-cylinder deadbolt, has a keyhole on the outside of the door and a notch on the inside that can be turned to lock or unlock the door. A turn of either the key or the notch sends a thick metal bolt inside the door jamb.
Double-cylinder deadbolt
-
A double-cylinder deadbolt is distinguished from the single-cylinder deadbolt by the fact that the portion inside the house has a keyhole rather than a notch. While sometimes inconvenient for day-to-day usage, this can help thwart more technically-proficient burglars.
-
Surface-mount deadbolt
-
A deadbolt where a D-shaped apparatus is mounted on the inside portion of the door itself, the surface-mounted deadbolt can help prevent a burglar from hammering off the deadbolt from the outside. However, it can be unsightly and difficult to install in certain circumstances.
High-security deadbolt
-
While more expensive, a high-security deadbolt can be a valuable defense against those who know how to pick locks. Look for designation on the packaging that indicates that the lock includes sturdier cylinders and differentiated pin arrangements.
Handle Set
-
Those concerned about the aesthetics of a deadbolt can purchase a lock with a visually-pleasing handle on the outside and a keyhole on the inside of the door. A second deadbolt is typically placed above the handle in such an arrangement so that the door can be unlocked from the outside.
