How To Choose The Best Deadbolt Lock

It is worth keeping in mind that anytime your house is not adequately secured, it is in imminent danger of being broken into and robbed. One effective way to increase your home security is installing a deadbolt lock on all your exterior doors and entry points. Given the critical role deadbolt locks play in home security, it makes sense to know as much about locks as you can, and that’s where articles such as this become invaluable.

In 2021, the national rate of burglaries in the United States was 271.1 per 100,000 people. This is a drop from the previous year when the rate of burglaries per 100,000 people was 308. With these statistics in mind, ask yourself this question: Will your locks provide adequate security when a determined intruder attempts to enter your home?

To increase the security of your property, you may consider installing deadbolt locks. However, before installing any locks, you should equip yourself with relevant information, such as deadlock bolt prices and details on the types of locks available and lock grading. Once armed with this information, you can make the best decision regarding what locks to purchase.

What Is a Deadbolt Lock?

Deadbolt locks are locks that contain a bolt that slides into a strike plate that is attached to the door frame. The bolt prevents a door from being pushed or pulled open when locked. Deadbolt locks are not spring-operated and can only be opened using the applicable key. Deadbolt locks are renowned for their sturdiness and the high level of security they offer. Because they are not spring-operated, they are more difficult to “jimmy” open and are significantly more resistant to brute force.

Types of Deadbolt Locks

Check out the types of deadbolt locks below and choose the best one to suit your specific needs:

Single Cylinder Deadbolt Lock

A single cylinder deadbolt lock has one cylinder and can only be operated from the outside using the correct key. However, the lock can be opened from the inside (or interior) without requiring keys, as it features a thumb knob or lever.

The thumb turn feature makes the single cylinder lock convenient and easy to operate. However, the trade-off for the extra convenience is lesser security. Single-cylinder deadbolt locks are more accessible, easier to operate, and more convenient than double-cylinder deadlocks. Still, at the same time, they are not the strongest or sturdiest locks available, which means they provide a lesser degree of security than double-cylinder deadlocks.

Double Cylinder Deadbolt Lock

As the name suggests, double-cylinder deadbolt locks have two chamber configurations and two key slots on both sides. It does not have a thumb turn; it can be locked and unlocked only by utilizing a matching key.

If you choose to utilize double-cylinder deadbolts, you should always keep the key with the rest of your belongings. Alternatively, install double-cylinder locks only on doors you will not use during an emergency.

Vertical Deadbolt Lock

Although deadbolts are resistant to physical force, they are not without flaws. On horizontal deadbolts, a burglar may be able to open a door from its jamb. Vertical deadbolt locks eliminate that threat.

The bar of a vertical deadbolt ends in a collection of rings. These rings are compatible with the rings on the door frame. Built inside the bar is a vertical shaft that slides through the rings and secures the door in place.

If an intruder wishes to breach your vertical deadbolt lock, they must apply sufficient force to detach the jamb from the frame. Because of this, vertical deadbolt locks offer far more superior security than single and double cylinder deadbolt locks.

Deadbolt Lock Grading System

There are three categories of deadbolt locks that define their level of security. Grade 1 is the highest and is considered the best deadbolt lock.

American National Standards Institute (ANSI) assigns the lock grades. This non-profit organization was founded by the Builder’s Hardware Manufacturers Association (BHMA) to provide industry-specific standards.

ANSI Grade 1

Grade 1 classifies deadbolts as “commercial grade.” These locks are often used on commercial properties because they are considered high-security deadbolt locks.

For a deadbolt lock to earn Grade 1, it must comply with the following tests:

  • Tested to a maximum of 250,000 open/close cycles.
  • The bolt extends one inch into the door frame.
  • Able to sustain ten 75-pound hammer strikes without yielding.

ANSI Grade 2

Grade 2 indicates that the deadbolt lock is “commercial grade” and has a moderate price. These locks undergo less rigorous testing than locks that meet Grade 1 requirements. They are typically seen on residential properties.

ANSI Grade 3

Grade 3 locks are not required to bear nearly as much force as Grade 1 or Grade 2 locks. Grade 3 deadbolt locks are only required to withstand two blows of force. As the lock with the least resistance, they are frequently employed as a supplemental security precaution on doors.

Factors to Consider When Choosing the Best Deadbolt Lock

If you’re planning to get a deadbolt lock for your home or business, here are some of the things you should consider before purchasing one:

1. Consult Experts

Officers of the law and experienced locksmiths have a wealth of knowledge regarding the potential weaknesses in your home and the preventative steps you can take to thwart burglars. Consider setting an appointment for a member of the local police department or a locksmith to visit your home, inspect your entry points and current locking mechanisms, and provide recommendations for upgrades.

2. Function Before Aesthetics

Everyone desires attractive door locks, especially on the front door. However, when purchasing locks, the functionality must come first. Undeniably, the type of lock you would install on a bedroom or bathroom door for privacy purposes does not need to provide the same level of security as the locks on your front and rear doors.

3. Lock Grading System

As previously discussed, the American National Standards Institute (ANSI), the Builders Hardware Manufacturers Association (BHMA), and Underwriters Laboratories (UL) all grade locks and deadbolts. (Please refer to the section above for the detailed information about the lock grading system.) You can also use the BHMA website to compare locks and determine whether or not the locks you’re considering are BHMA-certified.

4. Price Level

Cost is a common consideration when deciding which locks and deadbolts to purchase. Deadbolt lock prices will, of course, vary depending on the grading and the type you choose. High-security locks may appear costly, but they typically include hardened cylinders, unique pin arrangements, and other built-in defenses. In general, higher-priced locks provide better quality and security.


Installing the best deadbolt locks on all external door entry points is a crucial first line of defense against burglars. While no lock is ever 100% guaranteed to keep an intruder away, knowing which deadbolts may minimize risk and give additional protection is useful when selecting locks for your home. Consider all the tips and information mentioned above to help you make informed purchasing decisions.
