The most advanced real estate lockboxes
Secure and reliable
Our lockboxes undergo more extensive independent security testing than any other product on the market, as well as rigorous testing for operation in various outdoor weather conditions. Built with high grade user-replaceable batteries, you should be able to get 14+ years of usage from our lockboxes.
Strong but accessible
FlexCodes® and our SentriConnect® mobile app are easy, secure ways to grant temporary secure access to a lockbox on a certain day, at a certain time, and for a certain duration to a specified non-SentriLock user.
Features you’ll APP-reciate
SentriLock’s accompanying mobile app puts you in total control and delivers convenient lockbox features such as property details, access notifications, showing instructions, and even an industry-best feature to help keep you safe.
... And the other thing I really love about it (SentriLock), is that I know that I’m taking really good care of my sellers when I have a lockbox on there that I know that no one’s going to be able to break into, and I know it’s going to be easy for REALTORS to access.
