SentriKey® Lockbox

Much more than just a key safe.

The SentriKey lockbox is a commercially graded electronic key safe that offers the most secure and fully traceable property access. It is used in conjunction with the SentriKey Access platform and mobile application.

Designed and manufactured in the US from the highest quality materials to withstand severe intrusion attempts, SentriKey lockbox incorporates Bluetooth technology for key access and visit auditing.

The tried and tested electronic key lockbox can be opened by authorised users with the SentriKey® Access app. Alternatively, a one-day code can be generated for emergency access or one-off visits. The allocated access is named and tracked, eliminating the code management security issues associated with mechanical key safes.

Accredited world class security rating

Put through the most stringent independent security testing, the SentriKey lockbox is the only key safe, alongside with SentriGuard®, approved for use on commercial property.

Bluetooth technology

The lockbox uses a localised Bluetooth connection to allow mobile app access even in the most remote locations. The access data is uploaded to the platform as soon as the app user’s phone signal is restored.

One-day code access

Every access code generated for one-time users, such as contractors, expires at midnight. This eliminates the security risks associated with traditional mechanical key safes, which require a manual code change onsite.
