You're probably thinking about buying some new door locks. It could be for your house or business. But because there are so many locks, door hardware, and brands to choose from, you might be unable to figure out which one will work best for you. It's not an easy choice, and you should consider a few things about lock grades before deciding.

To choose the best secure locks, you should first learn about the American National Standards Institution's system for rating locks (ANSI) set by the Builders Hardware Manufacturers Association.

According to the American National Standards Institute (ANSI), locks can be graded depending on their security level and resistance to the most common attacks. 

Forty-two various standards cover door closers, locks, and emergency exit devices at the moment. The standards outline all the tests and features that must be implemented to ensure that goods perform as planned. A lock of "ANSI Grade 3" provides a minor level of protection, while a lock of "ANSI Grade 1" is the most secure currently on the market.

Why Do You Need To Know About Security Ratings? 

Organizations with maximum security ratings have a better overall security posture. Thousands of businesses like yours use high-security locks to help you identify and mitigate a wide range of interrelated security issues. 

High-quality door locks must ensure the safety and lock's security, whether it be a private dwelling, commercial establishment, or another type of property. Choosing the right lock for the door, it will be installed on is also crucial. 

Most thieves begin their hunt for a way into the home by forcing their way through the door because it is one of the most accessible entry locations. Installing the correct lock on your home will make it more difficult for intruders to gain in, increasing your sense of security. 

Together with the builder's hardware manufacturers association (BHMA) and others in charge of standardization, ANSI established a series of door lock grades. Here, you'll find the lock grades explained.

American National Standards Institute Grade 1 (ANSI Grade 1)

The most secure door lock on the market is the ANSI Grade 1 door lock. It is almost impossible to pick or break these locks, and if you do something to the lock's internal parts, like take out pins or screws, the locking mechanism will no longer work. 

Most of the time, they are used in business and high-security places like banks and office buildings. Because of this, they are also becoming more and more popular in residential settings of mortise locks.

The ANSI Grade 1 lock is the safest and most expensive lock you can buy for your home. For an ANSI Grade 1 lock, you should look for one made to keep burglars out from the key-in knob. 

This lock has at least five pins within the big box store. The key is hard to copy, and the locks are strong enough to stand up to heavy pressure and attempt to bump the locks.

Before they are considered safe within commercial buildings, Grade 1 door knob locks must be tested over 800,000 times and be able to handle 360 pounds of weight and six door strikes. Before they can be considered safe, deadbolts must be able to withstand 250,000 cycles and at least ten hammer blows to the door. This makes sure the product can handle the needs of the professional market.

American National Standards Institute Grade 2 (ANSI Grade 2)

For homes, you should install ANSI Grade 2 door locks. They are safer than a regular door lock but less secure than a Grade 1 lock. But when it comes to security, they are not as good as Grade 1 locks. Because of how they are graded, they are not suitable for any business building.

Based on 600,000 tests, the lock will last at least 25 years in your home before it needs to be replaced. You'll need the key that came with it to open the lock.

Grade 2 door knobs are made to meet the security needs of most apartment buildings and make picking the lock harder. Even though a grade-two deadbolt is more secure than a regular doorknob, it doesn't protect against picking or bumping anymore. They are a good choice for most homes if you want something that will last a long time and won't be easy to break.

Locks that meet the ANSI Grade 2 standard are still an excellent choice for homeowners who want to make their homes more secure without spending too much. They are the locks that people use most often today.

American National Standards Institute Grade 3 (ANSI Grade 3)

The ANSI Grade, 3 door lock, is the least secure of the three grades of security locks. The way these locks are made makes it impossible to open them without first putting a key inside and turning it. 

Their anti-drill features make it harder for people to drill through them with power tools, but they don't protect against lock picking or bumping. But they don't protect against lock picking or bumping.

ANSI Grade 3 door locks should only be used in low-risk situations or places where security is not a big deal. Your door locks must meet or beat the security requirements of your insurance company and any other local security requirements. 

This is the essential thing to think about when buying door locks. This is the most important thing to remember when shopping for door locks.

What Should You bear In Mind If You Want To Buy Good Graded Locks?

A Door Security Lock In Operation

To better comprehend how a product's grade is established, it may be helpful to have some details about the process and requirements. Several types of testing are broken down into operational, cycle, strength, and other parts in this standard (and in the majority of different lock standards). All tests are completed in a controlled laboratory setting according to specified protocols. Here is a detailed insight:


4.5 pounds of force is necessary for all grades, including testing to ensure that the door latches when closed. A second test is carried out on each lever to determine how much power is needed to retract the latch. Each lever must rotate with a force of no more than 28 inch-pounds to be approved for use.


The lockset is attached to a mechanical test door, and the test door is cycled until the required number of cycles is finished. It is then tested again to ensure the door is operating correctly. The grade one exam has one million cycles, while the grades two and three assessments each have 800,000 cycles.


Structural strength tests are performed to ensure that door hardware such as trim and latches can survive the wear and tear of everyday use, such as applying tremendous force to a lever, without losing their functionality. For all of the tests in this section, the lever must be pressed with a staff of at least 360 pounds for each grade.

There are many reasons why people might need to change the locks on their doors. People usually need locksmith services to replace or get new locks for new entries. No matter why you need a new wave, this list of things you should consider before buying one will be beneficial. Here are some of the best smart locks for your home, such as our Fluent system.

What Should You Bear In Mind Before Buying Security Locks?

Locks, however, are not made in the same way everywhere. No one lock can be used on any door in any situation. In reality, some locks are made to do one thing in particular. To ensure you buy the right lock, you need to know what kind of lock you can use.

Homeowners can choose from different types of door locks. Even though some of these locks work better in certain places, they can all be used inside and out. For example, an outside door with a deadbolt lock will be very secure. On the other hand, door lever locks are less secure than deadbolt locks and work better on doors inside the house.

The Safety Level Of The Lock

Ensuring the utmost safety with safety lock

Many homeowners don't know that locks have security ratings, but they do. Most lock makers have their locks tested and rated or graded based on how well they work. These numbers are meant to give you an idea of how strong, durable, and safe the lock is. 

The American National Standards Institute (ANSI) and trade groups for building hardware manufacturers regularly test and grade these locks (BHMA). They are grouped by how much force they can take and how many times the safety has to be used before it starts to wear out. 

ANSI Grade 1 deadbolts are more robust and can be used 600,000 more than Grade 3 deadbolts. So, if you're looking for security locks for your front door, you should look for something with a higher rating.

When buying a new lock, homeowners should pay attention to the lock's grade and rating. So, they'll know how long their locks will last and what kind of lock will give them the most security.

The Details Of The Lock

You need to know what a lock can handle before you buy it. I'll break it down a bit to help you understand. Not everyone can use the same lock. 

That's why people who own their homes should pay close attention to the features (like keypads and locksets) of any new locks they're thinking about putting in. 

Some locks have built-in features that make it hard to open them. For example, anti-bump, anti-drill, and anti-pick locks can help keep your property much safer than locks that don't have these features.
