Are you confident in the security of your business? ANSI Commercial Deadbolt Locks play a critical role in protecting your property.
ANSI (American National Standards Institute) sets industry standards for locks, ensuring quality and reliability. Commercial-grade locks are designed for higher security, making them essential for businesses.
In this post, we’ll explore what ANSI Commercial Deadbolt Locks are, why they matter, and the difference between Grade 1 and Grade 2 locks.

ANSI, or the American National Standards Institute, is an organization that develops safety and quality standards. These standards apply to a wide range of products, including locks.
ANSI sets the bar for reliability, durability, and performance in locks, ensuring they meet specific security needs. Their certification guarantees that products, like ANSI Commercial Deadbolt Locks, are tested and meet the highest standards.
An ANSI Commercial Deadbolt Lock is a lock built for higher security than standard residential locks.These locks are designed to withstand more frequent use, as well as physical attacks such as tampering or forced entry.
Unlike home locks, these are intended for environments like offices, retail spaces, and banks, where security is critical. Their robust design ensures safety in areas that need extra protection, like hospitals and government buildings.
The ANSI grading system classifies locks into three grades: Grade 1, Grade 2, and Grade 3.
| Grade | Tests Passed | Ideal Use Case |
|---|---|---|
| Grade 1 | 250,000 cycles, resistance to severe physical attacks | High-risk, high-traffic areas like banks and government buildings |
| Grade 2 | 150,000 cycles, moderate resistance to physical attacks | General commercial use, such as office buildings and retail stores |
| Grade 3 | 100,000 cycles, less resistance to tampering | Residential or low-risk environments |
Grade 1 locks are the most secure. They undergo rigorous tests, including 250,000 cycles of operation and resistance to severe physical attacks. These are ideal for high-security areas, like banks and government buildings.
Grade 2 locks provide a solid balance between security and cost. They undergo 150,000 cycles of testing and are suitable for general commercial use, such as office buildings and retail spaces.
Grade 3 locks are the least secure and are primarily used in residential settings. They undergo fewer tests and are suitable for lower-risk environments.
Each grade ensures that a lock is reliable for its intended purpose, whether it’s for a high-security facility or general commercial use.
Grade 1 locks are the highest security standard for commercial deadbolt locks. These locks must pass extremely rigorous tests to ensure their durability and resistance to tampering.
To be classified as Grade 1, a lock must endure 250,000 cycles of durability testing, according to the ANSI/BHMA A156.36 standard. This ensures the lock remains functional through heavy use. Additionally, Grade 1 locks must withstand physical tests that simulate forced entry attempts, including prying, drilling, and sawing.
Grade 1 locks are designed for high-security environments. They are commonly used in critical infrastructure like banks, government buildings, and military facilities.
Examples of Grade 1 locks include high-end commercial deadbolts that are engineered for maximum security in demanding environments.
Grade 2 locks provide strong security but are slightly less robust than Grade 1 locks. These locks undergo 150,000 cycles of durability testing, ensuring they’re durable for moderate use.
Grade 2 locks are also tested for resistance to forced entry, but the security features may not be as heavy-duty as Grade 1 locks. They are ideal for general commercial use, including offices, retail stores, and schools.
These locks strike a balance between affordability and security, making them a good choice for environments that don't face the same level of risk as high-security areas.
When deciding between Grade 1 and Grade 2, it depends on your security needs.
| Lock Grade | Ideal Use Case | Security Level | Cost |
|---|---|---|---|
| Grade 1 | High-risk areas like banks, government buildings | Maximum security, heavy-duty tests | High |
| Grade 2 | Moderate-risk areas like offices, retail stores | Solid security, moderate tests | Medium |
Grade 1 is best for high-risk, high-traffic areas where maximum security is required. It's perfect for financial institutions, government buildings, and other facilities requiring top-tier protection.
Grade 2 is more cost-effective and suitable for moderate-risk areas like office buildings and retail stores, where security needs are important but not as critical as in Grade 1 areas.
While Grade 1 locks offer higher security, Grade 2 locks are a good option for businesses looking for a balance of cost and reliable security.
When selecting the right ANSI Commercial Deadbolt Lock, consider several factors:
Security level: What type of protection does your business need? High-risk areas like banks or government buildings require Grade 1 locks. Moderate-risk areas, such as office buildings, can typically use Grade 2 locks.
Frequency of use: If the lock will be used frequently, choose a model designed for durability. Grade 1 locks undergo more rigorous tests for frequent use.
Environmental factors: Is your lock exposed to weather or physical threats? Some areas might require more weather-resistant materials or additional security features.
Budget: Determine how much you're willing to spend. Grade 2 locks offer a solid balance between security and cost, making them a good option for businesses with limited budgets.
By assessing your business’s risk profile, you can match the right lock grade to your needs.
When choosing between Grade 1 and Grade 2, ask yourself:
What is the security risk at my facility?
How often will the lock be used?
What is my budget for security?
If you're unsure, consult a security provider to evaluate your needs. They can help assess the type of facility, traffic, and potential threats. Balancing cost, durability, and security is key.
For general office environments, Grade 2 locks are usually sufficient. However, if you’re dealing with high-risk or critical infrastructure, Grade 1 is the better choice.
ANSI Commercial Deadbolt Locks are built to last much longer than typical residential locks. Designed for high-use environments, they undergo rigorous testing to ensure durability.
