Welcome to the Homebuilders Hardware blog, where we’re devoted to arming you with the insights you need to make the best decisions for your home or commercial space. Today, we dive into a critical part of property security: the age-old debate of the single cylinder vs double cylinder deadbolt. Both offer unique strengths, and selecting between a single-cylinder deadbolt and a double-cylinder deadbolt ultimately depends on your specific security requirements and convenience preferences.
What is a Single Cylinder Deadbolt?
A single cylinder deadbolt operates with a key on the outside and a thumb turn on the inside. This type of lock provides a balance of security and convenience that makes it a popular choice among homeowners and commercial spaces alike. Note that this type of deadbolt should not be used when a window is in proximity to the door, as an intruder might be able to break the window and reach in to access the thumb turn.
What is a Double Cylinder Deadbolt?
A double cylinder deadbolt, on the other hand, lacks the thumbturn and instead requires a key to unlock from both the outside and inside. This design provides an additional layer of security, making it nearly impossible for intruders to enter even if they can reach the lock through a nearby broken window.[1] That security, however, is diminished if the keys are left inside the deadbolt on the indoor side for convenience. Keys should be kept in proximity to the door, but not in the lock itself.
Single Cylinder vs. Double Deadbolt: Which is Better?
Both single and double cylinder deadbolts serve their unique purposes and excel in different areas. Let’s break down the main factors you should consider in this single or double deadbolt dilemma.
- Security
In terms of sheer security, the double cylinder deadbolt stands out. Its key-operated interior and exterior make it more challenging for burglars to break in, even when windows are close to the door. Breaking a nearby window will not allow access because they need a key to unlock the deadbolt, even from the inside.
- Convenience
When it comes to convenience, the single cylinder deadbolt shines. The thumb turn mechanism allows for quick and easy exiting in case of emergencies, or instant locking during security situations, features the double cylinder lacks due to its key-operated interior.
- Fire Safety
In the event of a fire, a double cylinder deadbolt could pose an escape obstacle if the key isn’t readily accessible, making the single cylinder deadbolt the safer option. This is sometimes required by fire regulations (check your fire codes).
- Insurance Requirements
Some insurance companies prefer the double cylinder deadbolt due to its added security level – always check with your insurance provider before making a decision.

I know people who leave their keys inside the deadbolt simply for convenience. They haven’t thought of the risk of doing that. Here is a good place to give them a tip not to leave their key handing within the deadbolt from the interior. A better solution is to store the keys nearby for convenience, but not leave them sitting in the deadbolt itself.
