The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across verified-purchase reviewers, the Master Lock 5441EC is the brand's app-connected wall-mount key safe, offering Bluetooth control and sharable keypad codes alongside a physical keypad. It draws on Master Lock's mechanical-lock reputation while adding the smart-access features that the cheaper 5400D and 5401EC lack. The rating picture is mixed: roughly 1,000 ratings at a 4.2 average, lower than the company's mechanical boxes and on par with the smart competition.

Across verified-purchase reviewers, the Master Lock 5441EC is the brand's app-connected wall-mount key safe, offering Bluetooth control and sharable keypad codes alongside a physical keypad. It draws on Master Lock's mechanical-lock reputation while adding the smart-access features that the cheaper 5400D and 5401EC lack.
The rating picture is mixed: roughly 1,000 ratings at a 4.2 average, lower than the company's mechanical boxes and on par with the smart competition. With no independent lab tests or specialist-community discussion in the supplied data, that softer average is the main cautionary signal we can surface, and it tracks with the broader pattern that Bluetooth-and-app key hardware tends to generate more reliability complaints than purely mechanical units. The relatively high price compounds the risk.
For buyers committed to the Master Lock ecosystem who want sharable codes and app access in a wall-mount format, this is the on-brand option, but the consensus is notably less enthusiastic than for the company's mechanical boxes.
