The future of real estate has arrived. We know how important a seamless on-the-market experience is for you and your clients; that's why we offer the latest lockbox technology.  

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. 

SentriLock has published a General Overview video of the SentriKey® Real Estate Mobile App, as well as a deeper dive into the application's Enhanced Features.

How to Access SentriLock Lockboxes with No Cell Coverage

May 6, 2021, 10:13 AM by Chris Barranco
NVAR recognizes how important it is that Realtors® feel confident and prepared using the SentriKey® Real Estate Mobile App, even in areas with little to no cell phone coverage. The information in this article will detail this process, for both the Bluetooth (Gray) lockbox and non-Bluetooth (Navy Blue) lockboxes.


How to Access SentriLock Lockboxes with No Cell Coverage

The Northern Virginia Association of Realtors® (NVAR) is your partner for information regarding seamless and secure access to your SentriLock lockbox. With the SentriKey® physical card retiring Jan. 1, 2022, NVAR’s mission is to help members learn more about the SentriKey® Real Estate Mobile App.

NVAR recognizes how important it is that Realtors® feel confident and prepared using the SentriKey® Real Estate Mobile App, even in areas with little to no cell phone  coverage. The information below will detail this process, for both the Bluetooth (Gray) lockbox and non-Bluetooth (Navy Blue) lockboxes. 

For Bluetooth Lockboxes (Gray Lockboxes) 

All users should refresh their SentriKey® Real Estate app credentials each day. You can think of this as the same process as plugging your physical card into the card reader each day. Whether you are a Listing Agent, Showing Agent, or an Affiliated User, before you leave home or the office, launch the Sentrikey® Real Estate app on your mobile device.  After authenticating, your credentials are good for 24 hours. After doing so, when interacting with the SentriLock Realtor® Bluetooth lockbox, it requires only your Bluetooth connection to open the key door, even if you're out of cell coverage.

For non-Bluetooth Lockboxes (Navy Blue Lockboxes)

If you're going to a showing in a remote area and that listing is not using a Bluetooth Lockbox, we have an answer for you, too. The My Schedule function in the SentriKey® Real Estate App is your solution, and this can be facilitated through the Listing Agent, creating the appointment directly in the SentriKey® Real Estate system. Once the showing is scheduled, and the SentriKey® Real Estate app detects low or no cellular coverage, a Mobile Access Code will be presented in the SentriKey® Real Estate app. You will then enter this code in your lockbox. No card needed, no reception needed, no Bluetooth needed.
