Buyer’s Guide

The key to making sure that you get the best double cylinder deadbolt is to find one that suits your every need and preference. To do that, you have to know what factors to watch out for first.

1. Deadbolt Type

Although this review is mainly about double-cylinder deadbolts, you first need to identify which type of deadbolt you truly need. Here are the different kinds of deadbolts:

Single Cylinder Deadbolt

A single-cylinder deadbolt is highly similar to a double-cylinder deadbolt. However, their significant difference is that a single-cylinder deadbolt only has one side that requires a key.

Single-cylinder deadbolts are commonly used in residential properties. Unlike double-cylinder deadbolts, they are legal in most states. However, the downside of it is that it is not as secured as double-cylinder counterparts.

The level of security that a single-cylinder deadbolt provides can be jeopardized if the door has a nearby window that burglars can break and enter. They can then unlock the door from the inside.

Furthermore, young children can quickly figure out how it works, so they might be able to go out of the house without anybody knowing.

Electronic Keypad Deadbolt

An electronic keypad deadbolt is perfect for modern homes. Some may even consider it as the future of deadbolts. Its mechanism is controlled by an electrical impulse that can be unlocked by entering a passcode. Some models also have a feature that allows the use of traditional keys.

Although electronic keypad deadbolts look great and modern, its major downside is that it can be susceptible to hacking. This is especially true if the burglars who are interested in gaining entry to your property are techy.

There are several ways to prevent this type of deadbolt from being hacked. One of these is to change the passcode frequently. However, this type of deadbolt is not great for those who are forgetful because entering multiple failed attempts may either sound the alarm or lock itself for around 15 minutes.

Keyless Deadbolt

As its name suggests, this type of deadbolt does not require any key to unlock. It can either use a card, mobile application, or a passcode. There are several variations of this type of deadbolt, and they provide doors with a modern twist.

Still, similar to electronic keypad deadbolts, it is also susceptible to hacking. Also, it is not ideal for those who are not good at memorizing passcodes.

Jimmy Proof Deadbolt

Jimmy proof deadbolts are typically found on the inside part of the door. It has an oval shape with bolts that slide up and down to lock and unlock. It operates using a knob on the inside and a key on the outside.

This type of deadbolt has been widely used in many old homes. It does provide an added layer of security, but it has a similar downside to using single-cylinder deadbolts.

Touchpad Deadbolt

Touchpad deadbolts work similarly with keyless deadbolts and electronic deadbolts. There can be several ways to unlock a touchpad deadbolt. Some of the most popular ones are by using passcodes, mobile apps, and keycards. More advanced touchpad deadbolts use eye or fingerprint scanners.

This type of deadbolt is truly revolutionary. It is a combination of an old-school concept and modern-day innovation. However, similar to the keyless deadbolts and electronic deadbolt, it can be vulnerable to hacking, which can undermine your property’s security.

2. Installation

When choosing a double-cylinder deadbolt, you must consider how easy it is to install. If you are planning to hire a locksmith to do it for you, then you will not have any problem since it is their expertise.

However, if you wish to do it on your own, you might want to check out whether the manufacturer provides a comprehensive instruction manual or a step-by-step tutorial online.

Aside from that, the installation procedure for each brand may differ from one another. As such, you really need to know beforehand if you can install it on your own or whether you have the necessary tools for it.

3. Material

One of the recommended materials to consider in choosing a double-cylinder deadbolt is stainless steel. Stainless steel is durable, and it does not easily break if somebody attempts to kick your door open.

Stainless steel is also highly resistant to corrosion, so it works well if used for main doors. This means it would be able to withstand changing weather and climates, making sure that it will last for years to come.

4. Finish

Deadbolts are primarily made for security, but that doesn’t mean that they should look ugly. Deadbolt finishes are not only visually pleasing, but it can also protect its hardware from corrosion.

There are several finishes for a deadbolt, depending on the manufacturer. The most common type of double-cylinder deadbolt finish is satin nickel.

Satin nickel is silver-grayish in color, which is what you typically see in doorknobs. If you prefer a vintage finish, go for those with a brass coating to give the deadbolt an antique look.

Lastly, if you want a modern and edgy finish, you might want to consider oil-rubbed finishes. These are black in color and would look good and add sophistication to a minimalist, contemporary home.

5. Anti-Rust Resistance

The best choice deadbolts are those that have an extra layer of anti-rust coating. Although some deadbolts are already made from stainless steel, which is already highly resistant to corrosion, an anti-rust coat guarantees that the deadbolt lasts for many years.

Remember, rust is not only unpleasant to the eyes, but it can cause serious injuries and operation problems on your deadbolt.
