SentriLock Announces Release of SentriGuard® Next-Generation Electronic Lockbox

New lockbox delivers the strongest, most reliable, and easiest-to-use real estate solution for secure property access.


West Chester, Ohio. (May 11, 2021) SentriLock, LLC, the leading real estate lockbox, showing service, and experience management solution provider, today announced the launch of SentriGuard®, its new flagship lockbox. Designed to create great experiences for real estate agents, buyers and sellers, SentriLock is the Official Lockbox Solution for the National Association of REALTORS®.

The SentriGuard® lockbox is packed with industry-first technology and easy-to-use features that make it the most secure and reliable lockbox on the market. Engineered with a high-strength, corrosion-resistant steel vault, bolt cutter-resistant shackle, and extra-large built-in key bin, the lockbox is built to last (independently tested and approved attack rating).

SentriGuard® leads the industry in device life with the longest-lasting battery – up to 10 years – that’s fully agent replaceable. SentriGuard® also has a built-in battery backup for ultimate reliability. Touch-N-Show™ NFC technology enables agents to open their SentriGuard® lockboxes with the tap of an NFC-enabled phone in less than two seconds – making it the fastest-opening electronic lockbox available.

The longevity engineered into each device is the result of an increased focus on sustainability in the company. The steel used to craft each SentriGuard® device is fully recyclable. The company estimates that 1.5 million lbs. of steel will be able to be recycled at the end of the line’s lifecycle. Lockboxes by design eliminate greenhouse gas emissions by housing a single key onsite, rather than necessitating roundtrip commutes to the seller’s agent’s office.

Incorporating input from hundreds of associations and thousands of agents, SentriGuard® features the most versatile secure temporary access options that ensure lockboxes are only opened by authorized people during scheduled times, facilitating the no- and low-contact showings that today’s buyer expects. The new lockbox incorporates more than 20 new innovative features.

“SentriGuard® is the latest in the line of property access advancements we’ve brought to the lockbox space,” said Scott Fisher, Founder and CEO of SentriLock. “We’re committed to pioneering technology-based solutions, backed by world-class customer service, designed to maximize productivity, ensure great client experiences, and provide the highest level of security innovation in the industry.”

The SentriGuard® lockbox with SentriKey® Real Estate software helps agents show and sell homes by enabling secure home access and putting real estate listing details at their fingertips. Unlike other lockboxes, SentriGuard® has multiple secure access methods that ensure agents are never locked out on the porch. Controlled access for every situation is easy, convenient, and safe.

SentriLock provides the first and only fully integrated lockbox and showing service platform that enables agents to manage home showings, client communication, and property access. Seamless lockbox and showing service integration simplifies the buying and selling process for agents, and helps create unmatched client experiences. SentriGuard® is the best-in-industry tool, at the best-in-industry price.

During our 18 years of providing technology solutions to the real estate industry, SentriLock has:

  • Enabled more than 10 million home sales.
  • Deployed more than 1.3 million lockboxes to agents and brokers.
  • Securely enabled more than 12 million home accesses annually.

SentriGuard® lockboxes will begin shipping to customers in May. Due to global supply chain disruptions, initial availability will be limited.
