The Internet of Things (IoT) aims to make any electronic device smart and communicating to other devices via the internet. The  Master Lock Outdoor Bluetooth Smart Padlock is not a smart device per se. However, it does have a iOS/Android app which extends its use from being a simple lock to one with extended accessibility.

It may not be intelligent enough today, however, with extended use this device can be integrated with the smartphone.

The feature set looks solid, and gives an indication of the direction of keyless locks, as well as the internet of things. However, it has not fallen off the edge of logic and maintains its main purpose to be only intended to be used as a lock.

One IoT takeaway from this device is that not everything has to be on the internet. This does come particularly close. If there are any concerns about its intelligence, suffice to say that being hacked by a third party, without the use of the app’s passcode, is silly..


The Master Lock Outdoor Bluetooth Smart Padlock is a smart Bluetooth lock. It lives up to its name, especially the ‘Outdoor’ portion. The heavy weather sealed design stamps this as capable of withstanding the natural elements.

To open this lock, you would need to have the a smartphone. Sorry, there is no other key. However, what is great about this is that you can send the code to anyone, allowing them to open the lock as needed. You can also set limits on when it can be opened. There is even a failsafe option where the device locks itself it it was opened by mistake.

It offers security at a price. This is not an inexpensive device, and to defray the cost, it should either work for a very long time, or it can be shared with others.

Our Score:
• Straightforward setup
• Hefty and strong
• Weather sealed
• Smartphone app allows sharing with other people.
• Optional two layer security
• Not cheap
