No Cell Service? No Problem! SentriKey has you Covered 

SentriKey Real Estate App can help make sure you stay connected. Here’s how:

For Bluetooth® Boxes
A good practice is to update your SentriKey Real Estate Mobile App credentials each day. Whether you’re 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. By authenticating, your credentials are good for 24 hours. When interacting with the SentriLock REALTOR® Bluetooth® Lockbox, it requires only a Bluetooth® connection to open the key door, even if you’re out of cell-service coverage.

For Non-Bluetooth® Boxes
If you’re going to a showing in a remote area and that listing isn’t using a Bluetooth® lockbox, we have a solution for you, too. Success is achieved by using the My Schedule function in the SentriKey Real Estate app. This is done either by the listing agent creating the appointment directly in the SentriKey Real Estate system, or through leveraging our integrations with other third-party showing services. When the showing is scheduled, and the SentriKey Real Estate app detects low or no cellular coverage, you’ll be presented with a Mobile Access Code in the SentriKey Real Estate app. No card needed, no Bluetooth® needed!


One-Day Codes

One-Day Codes are designed to support the integrity of the SentriLock system, while adding convenience for how access is granted to authorized professionals.

The following frequently asked questions and SentriLock’s recommended best practices will provide you with everything you need to know about using One-Day Codes and establishing proper use policies for your office. The One-Day Code Notification Form and information about One-Day Codes vs. Mobile Access Codes can also be reviewed or downloaded.

SentriConnect App: Your Secure Option for Providing One-Day Codes

Allows the listing agent, listing office, or anyone with lockbox owner privileges on an assigned property to issue One-Day Codes through the SentriConnect app. The app can be used for non-SentriLock REALTORS® and Non-REALTOR® users (cleaning companies, inspectors, etc.) to access One-Day Codes for listings.
