When you're managing a multifamily building project, access control isn't just a detail—it's a core part of your security plan. For Darby Constructions, taking on a large-scale development meant finding a way to streamline entry across dozens of units without relying on traditional keys. The goal was to provide a secure, modern, and accessible solution for tenants while keeping management tasks simple for the property team.

To meet that need, Darby Constructions turned to smart door locks—and specifically, the ADA Smart Door Lock. By installing 22 of these smart locks across one of their latest multifamily projects, they ensured each unit had consistent, keyless access. With smart functionality built in, the locks not only improved daily convenience but also made the entire system easier to maintain over time.

Working alongside Malcolm, a professional locksmith with experience in commercial installations, Darby Constructions successfully resolved any technical roadblocks during setup. The result was a well-coordinated rollout of smart door locks that delivered both security and scalability—a model worth exploring for any contractor or developer planning future builds.

Read on to discover how smart door locks made this project more efficient—and why they’re becoming a go-to solution for modern multifamily developments.

The Need for Smarter Access in Multifamily Projects

Managing a multifamily building means dealing with multiple doors, different tenants, and the ongoing task of handling access control. Traditional keys just don’t hold up in this environment. They’re easy to lose, hard to track, and costly to replace.

Smart door locks solve that problem. They allow property managers to issue digital access—via passcodes, keycards, or mobile apps—and revoke it just as easily. This saves time, adds flexibility, and improves the overall security of the building. For new construction projects, building in this kind of system from day one is more efficient than retrofitting later.

For Darby Constructions, choosing smart door locks wasn’t just about convenience. It was about preparing the building for long-term functionality, reduced overhead, and a better experience for the people who would live and work there.

Why the ADA Smart Door Lock Was the Right Fit

When it came to securing a multifamily building, Darby Constructions needed a lock that could do more than just open and close doors. They needed something reliable, versatile, and compliant with accessibility standards. The ADA Smart Door Lock delivered on all fronts.

This model is purpose-built for high-use environments like apartments, condos, and commercial facilities. It combines powerful smart features with a clean, functional design—making it an ideal solution for large-scale projects where both ease of use and long-term performance matter.

Here’s what made it stand out:

✅ Universal design with ADA-compliant lever handle
The handle is easy to grip and operate, meeting ADA accessibility standards—an important requirement in many residential buildings today. Whether used by tenants, maintenance staff, or guests, it provides a user-friendly entry experience for everyone.

✅ Remote access and management through a connected app
Property managers can lock, unlock, and monitor doors from anywhere using their smartphone. The app allows real-time control over each unit, eliminating the need for physical keys or on-site visits just to update access.

✅ Supports multiple access modes for different user preferences
Fingerprint scanning for quick touch access, passcodes for everyday users, RFID keycards for guests or building staff, and app-based control for remote entry. This flexibility allows different tenants to choose what works best for them—no one-size-fits-all limitations.

✅ Auto-lock and audit trail features
The lock can automatically re-lock after each use, reducing the risk of doors being left open. It also tracks activity logs, giving property managers insight into when and how doors are being accessed.

✅ Commercial-grade durability, designed for repeated use
The ADA Smart Door Lock is made to withstand constant handling in high-traffic areas. From heavy-duty housing to weather-resistant materials, it’s built for daily wear without sacrificing performance.

✅ Simple battery replacement and low-power alerts
Maintenance is straightforward. The lock notifies users when battery levels are low, and the replacement process is quick and tool-free—ideal for busy properties with multiple units to manage.

By standardizing on this smart lock across all 22 units, Darby Constructions streamlined both the installation and long-term upkeep. With one system in place, there’s less guesswork, fewer parts to troubleshoot, and better control for the entire property.

22 Locks, One Project: A Coordinated Installation with Expert Support

This wasn’t just a simple tech upgrade—it was a full-scale access control deployment built into the foundation of a multifamily property. Darby Constructions integrated 22 ADA Smart Door Locks across unit entrances and shared access points, all while working within an active construction schedule. A project of this size demands not only the right hardware, but also the right approach to planning and installation.

Each door had to be measured, prepped, and fitted to ensure a precise and functional setup. Proper spacing, alignment, and structural integrity are critical when installing smart door locks—especially those with fingerprint sensors, card readers, and motorized deadbolts. That’s where having an experienced locksmith on board made all the difference.

A Trusted Locksmith Role & Expertise from Start to Finish

Malcolm, a professional locksmith familiar with large-scale smart lock installations, was brought in to lead the on-site execution. His involvement ensured that the installation process didn’t just meet basic standards—it exceeded expectations.

With Malcolm on the ground, Darby Constructions was able to:

• Correct alignment and door fitment issues before installation, ensuring locks operated smoothly
  

• Minimize door modifications, preserving the integrity of the doors while maintaining a clean finish
  

• Test and verify all access modes—including fingerprint, keypad, card, and mobile app—on every lock
  

• Provide technical feedback and support to the construction team during setup and configuration

Malcolm also played a key role in solving unexpected site conditions—such as slight misalignments or spacing constraints that could have caused delays. Instead of stopping the process, he adapted, adjusted, and delivered results without compromising the schedule or functionality.

This level of support gave the Darby team confidence that every lock would be ready for use the moment the building opened. More than that, it ensured a polished, professional result that matched the quality of the project itself.

A Future-Ready Model for Contractors and Developers

Smart door locks aren’t just a tech trend—they’re becoming a practical necessity. As more tenants expect secure, keyless access and as buildings grow in size, the need for scalable solutions will only continue.

For contractors like Darby Constructions, smart door locks simplify operations, reduce service calls, and offer long-term value. And when paired with the right locksmith expertise, installation becomes a smooth and manageable process.

Conclusion

Darby Constructions didn’t just install 22 smart door locks—they laid the foundation for smarter access across an entire multifamily building. By choosing the ADA Smart Door Lock and working closely with a skilled locksmith like Malcolm, they ensured every unit had secure, code-compliant, and easy-to-manage entry from day one.

This project shows what’s possible when smart technology meets professional expertise. The result isn’t just convenience—it’s long-term efficiency, improved tenant experience, and reduced overhead for property managers.

If you’re developing or upgrading a residential or commercial building, the ADA Smart Door Lock is more than just a hardware upgrade—it’s a smart investment in scalable access control. And as Darby’s success proves, having the right locksmith by your side can turn a good plan into a seamless execution.
