Residential Management Group (RMG)

Before adopting this solution, an RMG employee had to make trips to the buildings to hand out keys to contractors and then retrieve them after the work was completed. This process consumed valuable time and incurred unnecessary costs for both contractors and RMG. Moreover, there were security concerns as keys were often mislabeled, not returned promptly, or not returned at all.

Compounding this challenge, RMG’s residential properties had a variety of hardware setups, requiring a system-agnostic solution to keep expenses in check.


Sentry Interactive offered a seamless building access control solution for RMG with Sentry Mobile Access, a mobile door entry solution, powered by Doordeck. For their doors without a network connection they utilized Sentry Interactive controller hardware, which linked any door to the Sentry Mobile Access cloud-based access system.

The Sentry Mobile Access software came equipped with features that addressed RMG’s challenges effectively. These features included time-limited digital visitor passes, instant onboarding, and remote credentialing, empowering RMG to manage access to their buildings without needing to be physically present.


RMG initiated a pilot program by incorporating Sentry Mobile Access into 10 buildings, comprising a total of 20 doors. This allowed RMG to test the installation of Sentry Mobile Access and gauge the response from building occupants. A further 4 buildings were added 6 weeks later to bring the total number of mobile access controlled networked doors to 34.

Sentry Interactive provided training to Residential Management Groups Business Analyst on how to usage and manage build access using the Sentry Mobile Access platform, granting them full control over RMG properties. After just one training session, the Business Analyst felt confident enough to train colleagues independently. With Sentry Mobile Access, RMG could instantly grant occupants access to the relevant doors using the remote onboarding feature and send digital visitor passes to on-site contractors.

James Hooper, the Business Analyst at RMG, recalled his first encounter with Sentry’s readerless mobile access solution, realizing the simplicity of the solution after mistakenly grabbing the wrong set of keys. He emphasized the significant time savings achieved by implementing digital visitor passes, resulting in approximately 280 hours of saved employee time per month, which was historically spent delivering and retrieving keys from contractors. Simultaneously, RMG could provide smartphone-based keyless entry to residents, ensuring their safety during the pandemic.


Within a mere two days, the Sentry Mobile Access software was fully integrated into the 10 pilot residential buildings owned by RMG. Residents provided positive feedback during the installation, with one tenant expressing enthusiasm for the safety and convenience of the system.

As a testament to Sentry Interactive’s user-friendly interface, minimal training was required. RMG staff swiftly provided instant door access to all willing building occupants, without imposing the product on those who preferred using traditional key cards and fobs.

Contractors also benefited significantly from the system, finding it simple and straightforward to operate, especially when accessing buildings with electronic gates.


The collaboration between Sentry Interactive and RMG has been a resounding success. Both RMG and its building occupants have expressed high satisfaction with the Sentry Interactive mobile entry solution.

  • The project commenced with 10 pilot residential buildings, each requiring 20 doors.
  • The solution has expanded to an additional 4 buildings, resulting in a total of 34 doors now supported by Sentry Interactive.
  • A remarkable 63% of RMG’s tenants swiftly adopted Sentry Mobile Access leaving behind their key cards and fobs.
  • Contractors have streamlined their building access through time-limited visitor door passes, used twice weekly.
  • Across the 14 trial buildings, RMG has saved over 56 hours of employee time weekly.
  • Annually, an impressive 2,912 hours of head office employee time has been conserved thanks to Sentry Interactive’s innovative solution.
