Very good item. Its particularly difficult to set people up to use the lock but once that's done it works fine.

Product purchased for an exposed location where access is required by a large number of different people and organisations. The build quality seems good, as expected from Master Lock. It does take a little while to set up, but the instructions make sense and it is worth a little effort.

This has still not been installed on site, so I cannot comment on how it stands up to corrosion. However, the app and Bluetooth work well and it may well prove to be a solution we can use at various properties and sites in the future.

Opted for a 7 for storage capacity as no idea how this effects a lock....

Recommended if you are looking for something for multiple access without issues of combination padlocks.

I love the concept of opening the padlock from your phone and highly recommend it. I also love the ability to give permanent or temporary guest access to others as that way you don’t have to worry about keys being misplaced or copied. I just wish that the app is also offered on the apple watch as it would better facilitate ease of use. The padlock itself is of superior and robust quality, although it could be made a bit more affordable. Make the app available on the apple watach and reduce the price of the lock itself and you’ll get 5 stars.

Loved the product, purchased for our outdoors netball courts.

So it need to be waterproof and robust.

It is brilliant, even if you do not have your phone on you the

directional code lets you in.

Highly recommend this product, not more lost keys to padlocks

How long does the battery last in the lock and do you get a warning when the battery power is low?
Paul Clarke, Andover
The battery will generally last 18-24 Months dependent on how much it is used. There is a low battery warning and there is an external point , which allows emergency power to be supplied to the padlock should the battery run out before it can be resolved.

Where do you get the directional code from is it sent to the app also can you then share it by sending it to someone?
Alicia, London
The directional code would be found within the APP. The Bluetooth Smart Padlock does not have a sharing function so sharing the code must be done manually.

Can I unlock this remotely using my iPhone? If I was away and someone needed to access the area could I unlock it from the app even if I am nowhere near the lock if I didn't want to tell the person the directional code?
Alicia, London
This lock can be operated using your phone, however you would need to be within Bluetooth connection range for this to work. The directional code could be used in this instance as it automatically resets and changes after its one time use.

Does this padlock support timed access? Only allowing a shared code to be used within a certain time.
Connor, Dereham
This padlock does not offer timed sensitive access. You may want to check the igloohome Smart Airbnb Padlock which does offer this feature.
