With the Master Lock Select Access - Bluetooth products, you always have the code in your pocket. Both the key safe and padlocks can be unlocked via bluetooth with the corresponding app. The administrator can use the app to control which people have access to the lock.
Different models
The Master Lock 5441 is a wall-mounted key safe with an 83 mm wide metal housing, built for durability. The ML 4400 and ML 4401 are robust padlocks in two different sizes, with the ML 4401 and ML 5441 suitable for outdoor use.

With the updated version, administrators can choose between the app for individuals (Vault Home) or the business edition (Enterprise). Of course, there is still the option of opening the lock via an (optionally temporary) manual combination code.
Individuals
The Vault Home app is suitable for use by individuals, such as families, babysitters or an AIR B&B. The administrator can invite up to 10 guests to use this lock and manage up to 10 locks from the app. The administrator can check back up to 90 days in the logbook that tracks who has been in which lock and when.

Business edition (Enterprise)
For business purposes where a larger number of locks need to be managed, it is more convenient to use the Enterprise software. The Enterprise software allows the administrator to access the web-based portal in which an unlimited number of locks and administrators can be added. The users of the locks are sent an invitation by e-mail to log in via the app, after which they can use the bluetooth signal from the app to open the lock. The administrator can also use the logbook to see who has been in which lock and when.
