The MAAR MLS uses the SentriLock lockbox system, developed to include some of REALTORS®' most frequently requested features. SentriLock's system is web-based so all lockbox settings and showing information are easily accessible from any computer, tablet or mobile device.

SentriLock® training classes are held every Tuesday at 1:30 p.m. in the Corner Conference Room at MAAR. Registration is required for weekly training classes. Members may contact Member Services, 901.685.2100, to register.

Discontinuation of SentriCards®

SentriCard® users be advised that SentriCards® are being discontinued. Effective Jan. 1, 2022, agents will no longer be able to use SentriCards® for lockbox access. SentriCard® readers will become inactive and SentriLock will end support for SentriCards® and all SentriCard® services.

SentriCard® will need to transition to using the SentriKey® Real Estate mobile app and/or website to access lockboxes. The SentriKey® Real Estate mobile app is available for Apple and Android devices via the App Store and Google Play.
