The deadbolt has a few different varieties, and HandleSets.com carries them all. A single cylinder deadbolt is the most popular choice for standard residential applications, like homes and apartments. Specific benefits of single cylinder deadbolts include ease of use and added security over a locking lever set or knob set. A single cylinder deadbolt can be locked or unlocked via a key on the exterior or a thumbturn on the interior.
Double cylinder deadbolts are ideal for placing on a door with glass or an entrance that has glass windows within reaching distance of the door. A double cylinder deadbolt includes key slots on both sides so a would-be intruder can’t just break a window to unlock the door. A double cylinder deadbolt is becoming increasingly against code, though, since it wouldn’t be easy to open a door with one in case of an emergency, like a fire.
One sided deadbolts can only be accessed on the inside. There’s no way to unlock (or pick) a one sided deadbolt from the outside. That’s good protection. One sided deadbolts come in spring latch or dead latch options.
Electronic deadbolts are the future of door hardware. This innovative deadbolt eliminates the need to carry around a key and grants access with a code of your choice. Most electronic deadbolts allow for multiple codes and temporary codes, so giving a guest or maintenance worker another code can easily be changed or deactivated after they have used it.
All electronic deadbolts have a low battery indicator which will keep you from being without your key and having a dead battery in your deadbolt.
