# Bluetooth-Connected Key Boxes The Master Lock Key Box Grants Access Based on Nearby Smartphones By Joey Haar | Published 2017-07-04 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/master-lock-key-box References: [digitaltrends](https://www.digitaltrends.com/mobile/master-lock-5441-bluetooth-key-box-news/) & [masterlock.eu](http://www.masterlock.eu/home-personal/product/5441EURD) In the past, giving multiple people access to the same set of keys required a leap faith by leaving keys in a goofy hiding spot or, even worse, under the welcome mat, but the Master Lock key box uses technology to make shared keys a more trustworthy process. Users can manage who has access to the Bluetooth-connected box through the Master Lock app, ensuring that only the right people can get their hands on the spare. Many houses might need to provide multiple people access to a spare key. A maid, a dog-walker, a babysitter, and other trusted individuals need to get into the house, but it's an excessive exercise in trust to give each person their own set of keys. The Master Lock key box can sense approved smartphones through Bluetooth, meaning that the right people can get access to it all on their own, without the need to even provide them with a key code. ## Trend Insights (Trend Hunter) - Score: 0.8/10 - Popularity: 10% | Activity: 7% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Gen X - Top markets: North America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [Gadgets](https://www.trendhunter.com/gadgets) ## Key Themes ### What's Driving This Trend - **Bluetooth-connected Key Boxes:** Key boxes that use Bluetooth technology to grant access based on nearby smartphones. - **Smartphone-managed Access:** Managing access to key boxes through smartphone apps for added security and convenience. - **Trustworthy Key Sharing:** Innovative solutions that provide secure and easy sharing of keys among multiple trusted individuals. ### Who This Affects Most - **Home Security:** Incorporating Bluetooth-connected key boxes in home security systems for enhanced access control. - **Hospitality:** Utilizing smartphone-managed key boxes to grant temporary access to service providers like maids and dog-walkers. - **Property Management:** Using key box technology to streamline the key handover process for landlords and property managers. ## Related on Trend Hunter - [Smart Lock Boxes](https://www.trendhunter.com/trends/robern-iq-digital-lock-box.md) - [Smartphone-Centric Smart Locks](https://www.trendhunter.com/trends/schlage-encode-plus.md) - [Biometric Scanner Smart Locks](https://www.trendhunter.com/trends/lockly-flex-touch.md) - [Fingerprint-Scanning Door Locks](https://www.trendhunter.com/trends/wyze-lock-bolt.md) - [iPhone-Connected Smart Locks](https://www.trendhunter.com/trends/level-home.md) - [WiFi-Enabled Accessible Smart Locks](https://www.trendhunter.com/trends/wyze-lock-bolt-v2.md) - [WiFi-Enabled Smart Locks](https://www.trendhunter.com/trends/yale-assure.md) - [High-Tech Residential Security Systems](https://www.trendhunter.com/trends/residential-security-system.md) - [Ultra-Secure Connected Door Locks](https://www.trendhunter.com/trends/netatmo-smart-door-lock-and-keys.md)
