Buyer’s Guide

The right double-cylinder deadbolt will significantly enhance your home security system.

However, you should consider certain features before choosing the right one that matches your door locking needs and requirements.

From essential screws to strike plates, below are some key things to keep in mind before shopping for deadbolts.

Strike Plate

One of the most important things to consider when investing in a double cylinder deadbolt is the quality of the strike plate in its composition.

A strike plate is a metal plate that attaches to the door frame and has a hole for the steel bolt.

If the strike plate is made from flimsy or low-quality material, it will not be able to withstand forced entry and protect against intruders.

Therefore, we recommend opting for deadbolts that come with reinforced strike plates to ensure your home’s security.

Lock Grade Rating

The best double cylinder deadbolt will always have a transparent rating by the American National Standards Institute (ANSI).

These ratings range from one to three and help distinguish the locks based on their durability and potential ability to resist breaking in.

Here is an overview of the rating scale:

  • Grade One

Deadbolt locks with a grade rating of one tend to the sturdiest and were used only once in industrial settings.

It is the highest level of rating that a deadbolt lock can receive, making these locks the safest.

  • Grade Two

Grade two deadbolt locks are most commonly used for residential settings these days.

They are mostly made with high-quality steel material that can withstand a standard number of forced entry attempts.

However, we recommend opting for grade one locks if your residential area has higher security needs.

  • Grade Three

Deadbolt locks with a grade three rating offer a substandard level of protection.

These are mostly preferred on secondary access points with higher graded locks installed on primary access points.

These locks are not designed to hold against forced entry and are not as durable as other graded locks.

Easy Installation

Residential deadbolt locks are specifically designed to fit any exterior door easily, thanks to their conventional pre-drilled holes.

They are easy to install, and you can do it without requiring any professional help.

However, if your deadbolt lock does not come with three-inch screws in the packaging, we recommend purchasing these separately.

Although three-inch screws are a standard part of the deadbolt packaging, you can replace them with smaller screws.

The larger screws attach the strike plate to the door frame and are comparatively sturdier than their smaller counterparts.

On the other hand, smaller screws cannot embed deep enough into the wall frame behind the door, making it easier for intruders to kick the door open and compromise overall security.

FAQs

1. Are Double Cylinder Deadbolts Safe?

Double cylinder deadbolts offer maximum safety and security to users.

Although homeowners more commonly use single-cylinder deadbolts, intruders can easily pick and unlock these locks.

For instance, single-cylinder deadbolts installed on doors close to windows can be unlocked easily by breaking the glass and reaching the turning mechanism.

On the other hand, double cylinder deadbolts require a key on both ends to lock or unlock.

It’s difficult for burglars to access any space or home despite a closeby window that they can break open.

Therefore, although these may not be as convenient as single-cylinder deadbolts, they remain the safest option for homeowners.

With their high safety standards, these locks are often ideal for families with young children or elderly suffering from conditions like dementia.

Nonetheless, these deadbolts also require additional care to secure the key that is essential for gaining access into spaces.

We also found that double-cylinder deadbolts are ideal locking mechanisms for sliding glass or screen doors and windows.

That is because despite breaking the glass or tampering with the screen, the intruder will require a key to gain full access to the area inside.

As such, double cylinder deadbolts are extremely safe and secure compared to single cylinder deadbolts.

2. Are Double Key Deadbolts Illegal?

It is always a good idea to check your local fire code restrictions before installing double key deadbolts.

In the event of an emergency, people may get entrapped in a house or building, especially if they don’t have the keys.

For safety reasons, some cities have made it illegal to install double-cylinder deadbolts in access areas that may hinder escape routes.

For instance, the uniform building code of the city of San Jose in California has prohibited homeowners and construction personnel from using these locks.

If you are unsure about your area’s regulation and local codes, we recommend consulting with a certified locksmith in the area.

These specialists are not only up to date with local guidelines but will also help you make an informed decision regarding installing double-cylinder deadbolts.

Ideally, you should only install double key deadbolts in access points where a clear plan for emergency escape has already been drawn.

3. What Is the Difference Between a Single Cylinder Deadbolt and a Double Cylinder Deadbolt?

The most obvious difference between a single-cylinder deadbolt and a double cylinder deadbolt is the number of key slots in each lock.

A single-cylinder deadbolt is designed to have a single key slot on one side and a turning on the other side.

This turning lever mimics the mechanics of a key, ensuring a locking mechanism from one side without requiring an actual key.

This side of the single-cylinder deadbolt is often installed facing indoors to provide an added sense of privacy and security.

On the other hand, the double cylinder deadbolt has a key locking mechanism on both ends, requiring a key to lock and unlock.

Despite the minor difference in design, both locking mechanisms are very different from one another in terms of functionality.

For instance, single-cylinder deadbolts are considered more practical, convenient, and cheaper, usually a prominent choice for everyday utility.

On the other hand, double cylinder deadbolts offer more safety and security.

4. Which Is Better Single or Double Cylinder Deadbolt?

Both single and double cylinder deadbolts have multiple benefits and drawbacks, so choosing one locking mechanism over the other is often a personal preference.

There are multiple features to consider when choosing the right deadbolt for your living space or workspace.

For instance, as a homeowner, if you are living in a neighborhood with comparatively compromised safety standards, then a double cylinder deadbolt may be better.

If you are in an area with fire threats, you may want to consider the single-cylinder deadbolt because of its easy access points.

Unfortunately, there is no sure-shot answer when asked which of the two deadbolts is better as both have varying functionalities.

5. Can a Deadbolt Door Be Kicked In?

Deadbolts are generally designed to be sturdy locking mechanisms that can withstand some level of force when kicked in.

Statistically, most deadbolts can easily withstand an ample amount of force ranging anywhere between 100 and 400 pounds.

While kicking in a deadbolt door may be difficult, it is not entirely impossible, especially if the door in question is not sturdily built.

Therefore, it is recommended that you invest in high-quality doors when installing deadbolts to ensure maximum safety and security against forced entries.

Final Recommendation

We found the Baldwin Prestige 385 to be the best double cylinder deadbolt locking system based on multiple factors.

For starters, it has a level two grade rating by ANSI, making it super safe and secure against forced entries.

Secondly, it is made with high-quality stainless steel material, which is not only resistant to rust and corrosion but will also not break if kicked in.

Finally, it has a side locking bar and supports SmartKey rekeying technology to counter lost or unreturned keys.
