Your LockBox Company


SentriLock, LLC, is 100% owned by the National Association of Realtors® and was formed in August of 2003. The groundwork for this venture was laid back in 2001 when the principals of MFM Software, Inc. of Cincinnati, Ohio formed a company named SentriLock, Inc. Its mission was to develop an electronic lockbox product for the real estate industry. MFM has been a major provider for real estate desktop software and web applications in the United States for more than 10 years. This NAR venture was a 100% member-driven initiative and has succeeded in its goal to provide viable competition in the electronic lockbox market.

After a successful beta test in early 2004, SentriLock’s first installation was on June 14th, 2004. Not quite one year later, we signed our 50th contract. Currently SentriLock has more than 500,000 lockboxes in use by over 250,000 Agents from over 207 different Boards, Associations and MLS’s in the United States and Canada.

Your members will find that SentriLock’s REALTOR® Lockbox is a refreshing change from prior electronic lockboxes they may have used. SentriLock has intelligently engineered this platform with a focus on functions and features which will simplify rather than complicate an Agent’s life. Our technology is sophisticated, but does not go so far as to include functions unrelated to secure and flexible control of key access. Our lockbox offers unique options for access control by the Listing Agent that no other lockbox offers.

Furthermore, as a NAR owned company, we are directly accountable to the real estate community – and not to corporate shareholders. Our first priority is to serve the industry with a quality product and great service at a low cost.
