How do I access a showing in a remote area if that listing is not using a Bluetooth Lockbox?

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.

Which jurisdictions offer access rights (Reciprocity) on my SentriKey Real Estate App?

Log into your account in the SentriLock system at Once you are logged in click on the “My Account” tab, then scroll down for the section “Authorized Regions”. This section will list all active areas that your SentriKey Real Estate App can access.

Can I purchase batteries for my lockbox from other distributors?

You can purchase batteries that fit the lockbox from suppliers other than SentriLock® and the Association, but you run the risk of voiding the warranty on the box if an electrical problem results.  SentriLock® encourages you to purchase Association batteries which we distribute on behalf of SentriLock in order to maintain your lockbox warranty.
