Deadbolt Lock Types

A deadbolt lock is one of the safest lock systems a homeowner can install for the security of the home. Deadbolt locks offer additional protection to the basic spring-bolt styled locks. With the absence of the spring bolt mechanism in deadbolt locks, retraction is impossible when force is applied on the lock. Here are the common deadbolt lock types.

 

 

DeadboltSingle Cylinder Deadbolt

The single cylinder lock is the most common deadbolt lock system. It is installed from the inside of the door – with a key cylinder at the exterior and a twist knob at the interior. The metal latch allows you unlock the door from the inside. It is a perfect choice for homeowners as it only allows free access from the inside with the latch, while restricting the access from outside with the key.

 


Double Cylinder DeadboltDouble Cylinder Deadbolt

Although the double cylinder is also installed internally, it is a more complex system. The twist knob feature is absent in the double cylinder, as the key cylinder is present on both sides. Whether you are in or out, you would need a key to gain access through the door. This is a big advantage because if there is a glass around the doorframe, an intruder cannot get access to the property with the twist knob. The drawback here is that in cases of an emergency, finding the right key may become a problem.

 


Keypad DeadboltKeypad/Keyless Deadbolt

This deadbolt type is also installed internally, but it does not require a key for locking and unlocking as it makes use of a numeric keypad which allows you set a unique secret code. The keyless/keypad deadbolt is unique as you totally do away with the need of a key.  As such, there is no chance of loss or theft of your key and if you think someone might have learned about your code combination, you can change it quickly.

 


Single Sided Deadbolt

Single Sided Deadbolt

This type of deadbolt has a single thumb turn located on the inside of the door while a key is used to operate it from the outside. This makes for convenience when you need to open the door for a visitor as you do not need to always have your key to open the door. The single sided deadbolt is a great option in areas where fire safety is a cause for concern – the lock system makes for easy exit when there is an emergency. The bore hole of the lock system is partially drilled through the door so no one can see the deadbolt from outside. However, the single sided deadbolt does not work for doors that already have a bore hole.
