Understanding the Basics of Commercial Door Locks

What Defines a Commercial Door Lock?

Commercial locks are specifically designed for businesses, schools, and healthcare facilities. These are ideal for establishments with high traffic and security needs. Unlike residential locks, commercial locks are highly durable. The hardware complies with safety regulations and is tamper resistant.

Why Are They Critical for Business Security?

Commercial locks protect your valuable assets and confidential information. They also ensure the safety of employees and visitors. Their robustness also ensures they can withstand frequent use without compromising security.

Types of Commercial Door Locks

Cylindrical Lever Locks

Cylindrical lever locks are popular for their simplicity and durability. These locks are easy to install and are ideal for interior doors in offices and classrooms. Examples include: Schlage ND Series and Sargent Grade 1 locks.

Mortise Locks

Mortise locks offer enhanced security due to their robust internal mechanisms. They are perfect for exterior doors in high-traffic areas. Examples include Corbin Russwin CL3800 Series and Yale 5400LN Series.

FAQs About Commercial Door Locks

What is the best lock for high-traffic doors?

High-traffic doors endure frequent use and potential wear and tear. Grade 1 locks, as defined by ANSI/BHMA standards, are the best choice for these scenarios. Mortise locks are great for exterior doors due to their robustness and longevity.

Cylindrical locks are another viable option for interior doors that experience heavy use. In addition, consider locks with anti-tamper mechanisms to further enhance security.

Retail stores and office lobbies must have strong locks. They have high customer foot traffic. The Sargent 8200 Mortise Lock and Schlage ND Series Cylindrical Lock work best. These are built for heavy use and meet commercial standards.
How do electronic locks handle power outages?

Electronic locks come with contingency measures to ensure continued functionality during power outages. Most models feature backup batteries to provide temporary power.

Some advanced systems also include capacitors that store energy for emergency use. For added reliability, electronic locks often include manual override options. These include a physical key, so you're not entirely dependent on electricity.

For example, a Kaba E-Plex Lock has battery backup and manual key override to prevent downtime. There are some environments where power reliability is a concern. Here, integrating a UPS with the building's access control system is smart. It ensures continuous power and improves security.
Can commercial locks be rekeyed easily?

Yes, many commercial locks make keying a straightforward and cost-effective process. Rekeying means changing the pins or wafers in the lock cylinder. This makes it work with a new key, but the old hardware stays. This feature is great for businesses experiencing high employee turnover. This helps them quickly restrict access.

Key-in-knob locks, cylindrical locks, and mortise locks typically support rekeying. Advanced systems, such as master key systems, let businesses rekey locks. They also keep a clear hierarchy of access control.

Brands like Kwikset and Schlage have locks with SmartKey technology. This lets you rekey them quickly, so you don't need a locksmith.
What are the differences between Grades 1, 2, and 3 locks?
The ANSI/BHMA grading system categorizes locks based on their durability and functionality. Here's a breakdown:
- Grade 1: The highest level of security and durability. It is suitable for commercial applications and high-traffic areas. These locks are tested for up to 1 million cycles and can withstand heavy force. Examples include mortise locks and high-security cylindrical locks.
- Grade 2: Medium-level security for lighter commercial use or heavy-duty residential applications. These locks endure up to 800,000 cycles and are ideal for interior commercial doors.
- Grade 3: Basic security for residential use or low-traffic commercial areas. These locks are tested for 200,000 cycles and offer minimal resistance to force.
Grade 1 locks and deadbolts are ideal for entrances to high-security areas. For example, the Corbin Russwin CL3300 Series and the Master Lock Single Cylinder Deadbolt. On the flip side, Grade 2 locks, such as the Schlage AL Series, work well for interior office doors.
How do you choose between a keyless lock and a traditional lock?

Choosing between keyless and traditional locks depends on several factors. These include convenience, security, and the specific needs of your facility.

Keyless locks provide modern conveniences like PIN codes, access cards, and biometric authentication. They are ideal for businesses where frequent rekeying would otherwise be necessary. They also provide audit trails, remote access, and smart building integration. This makes them a good fit for tech-savvy operations.

Traditional locks, on the other hand, rely on physical keys. These are often simpler and more affordable. They work well for small businesses or places where access stays the same.

For example, a Schlage Encode Smart Lock offers commercial door keyless entry with remote access via app.

On the other hand, a Medeco Maxum Deadbolt is ideal for those who prefer traditional methods. Consider hybrid solutions, which combine both options, for maximum flexibility and security.
