Glendale, AZ Master Key Systems Built for Business Efficiency

Managing multiple keys across several doors or buildings? ARCO Lock & Security offers custom Master Key Systems in Glendale, AZ to help you streamline access, reduce lost key incidents, and increase security—all while saving your team time and frustration. Whether you’re overseeing an office complex in Westgate, a warehouse off Northern Avenue, or a retail space near Arrowhead Towne Center, we can design a scalable system tailored to your business layout and employee access needs.


Our Glendale master key service is ideal for property managers, multi-tenant buildings, schools, healthcare facilities, and businesses that need varying levels of access control. From a single master key to sub-master systems for department managers, we’ll structure a secure hierarchy that keeps your property both accessible and protected.

We also offer fast, onsite service to reconfigure your current locks without needing a full replacement—perfect for adapting to staff changes or expanding your property footprint.


We proudly serve Glendale neighborhoods like Arrowhead Ranch, Cactus, and Ocotillo with rapid, professional service backed by decades of experience. From design to install, ARCO makes it easy to manage access without sacrificing control.

  • What is a master key system and how does it work?

    A master key system allows one key to open multiple locks, while individual keys still operate only their designated doors. This provides flexible access control within your property.


  • Is a master key system secure?

    Yes. We use high-quality, commercial-grade locks designed to maintain security even with shared key access. Properly installed systems are highly secure and convenient.


  • Can I rekey my existing locks into a master key system?

    In many cases, yes. We can evaluate your existing hardware and rekey it to function within a master system, which is often more cost-effective than replacing every lock.


  • Who typically benefits from a master key system?

    Commercial buildings, apartment complexes, schools, retail stores, warehouses, and medical offices are great candidates—any place where multiple access levels are needed.


  • How quickly can you install a master key system in Glendale?

    Depending on the size and complexity, we can often provide installation within a few days. Emergency services are available for urgent rekeying needs.
