...And the other thing I really love about SentriLock, is that I know 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 break into, and I know it's going to be easy for REALTORS® to access.

Anne Burroughs

Charlottesville Area Association of REALTORS®

The SentriKey® Real Estate app is just so easy to navigate and use. All I have to do is use my Face ID connected to my phone or enter my PIN and push one button on the box.

Then, just like that, the box opens! These SentriLock lockboxes make us look more professional in front of our clients because we no longer need to fumble to get the key out of the lockbox.

Stephanie Carter

Edmond Board of REALTORS®

SentriLock provided all the support we needed and more during the installation process to get our members up and running with their lockboxes. It has all been very easy for us. On top of that, the reciprocity with other marketplaces is seamless. My agents can go up to Tulsa and get into the lockbox without any issues.
