It works magically! Love it

I bought few other smart locks before I settled with Nuki, all the others expecting to modify your lock. Nuki was smarter by keeping the lock intact as is, including your key.

You just install your Nuki on top of the existing lock and the key.

They provide you with Key Fobs, and keypads if you need.

It also detect if the door is left ajar. Which is great.

The app is simple. You can invite your circle to use the app. I have few ideas of improvements:

I wish it will alert me if the door is left unlocked or ajar after certain time user can set.

You cannot resend an invitation. You need to delete and recreate the user to resend the invitation after 48hrs elapse.

I wish I can unlock the door with my Apple Watch using LTE not only through proximity of the Bluetooth. As I go walking with my LTE Apple Watch without my phone while sometimes I need to unlock the door for someone.

Quite satisfied

I’m quite satisfied, there are a few things that could be better with the autolock settings and the sensor magnet could work better with the autolock system. It is not good when you just need to go out with rubbish that is just outside the door and the door locks straight away, should be an option to happen straight away or have a delay by seconds and minutes or if you go a set distance away. And the sensor should disable autolock if the door is open and hasn’t been closed yet. The noise level is also quite loud but one gets used to it over time. I wouæd give it 5 stars if all this would be possible

Totally impressed

I previously had the ASSA Abbloy ENTR solution, it was not only a non smart device (lack of wifi and smart home integrations) but it failed constantly, the installers blamed the lock mechanism itself. When this arrived it was a pretty quick installation, and the app wizard for setting it up, a breeze. It simply works, it is amazing, I hope Nuki could make some other type of products, because this one (with the fob, keypad, and sensor) works so good, that you want to tell the people about it.
