SentriLock AppSentriSmart®, SentriLock’s mobile application, is designed for convenience and speed by utilizing the capabilities of your smartphone. Using GPS and the geo location data of the listing, SentriSmart® is able to find the listings in your immediate area, verify your identity using a PIN based security measure, and then create an access code for the lockbox. The listing agent is then immediately notified of the access and can begin scheduling their follow up.
