Harness the Power of your SentriKey® App

  • SentriLock has evaluated their keycard technology and concluded that they will be retiring the cards, and the non-Bluetooth lockboxes will become obsolete. This transition takes effect January 1, 2022. Instead of the SentriCard®, the SentriKey® Real Estate Mobile App will be the sole means of access for lockboxes.   
  • Advantages include:
    • Ability to access lockboxes without the need for Wi-Fi.
    • The refresh feature, which safeguards the private information linked to your account. This eliminates the possibility of Keycard loss or theft. 
    • No need for card renewals. 
    • Access to information regarding property listing and SentriLock partners.

SentriKey App VS SentriCard (1)

What should you do now? 

If you are a SentriCard® user, transition to the SentriKey® Real Estate mobile app. Over three-quarters of SentriLock lockboxes accessed in 2019 were through the app. In today’s fast-paced market, clients expect a seamless experience, even in an area without Wi-Fi service! Using the SentriKey® app paired with a Bluetooth-enabled lockbox avoids those awkward front-door moments when showing homes to clients.

The app enhances the user experience and offers dozens of features, including:  

  • No need for card renewals – ever! 

  • Real-time notifications when someone enters and leaves a property. 

  • The ability to use Touch ID and Facial Recognition for a more streamlined process. 

  • Access to property details through SentriLock’s listing partners. 

  • Additional features, such as: Agent Safety, report lost keys, list agent-information and more.
