For Bluetooth Lockboxes:
A good practice is for all users is to update your SentriKey Real Estate 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. So. 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 coverage!
