The lock works amazingly good, even though my double cylinder lock has no emergency function I still was able to use a key outside to push out the key that is inserted from the inner side of the door - the Nuki app has a cool feature called "Optimize locking" that allows to adjust an offset at which the lock stops at locked/unlocked positions so that the inner key is always at a default position enabling the use of an external key! Love the app, the Auto-unlock and the Google Home integration!

Setup is badly guided. The custom cylinder parts to size it are incorrectly suggested so that it will never fit together. I managed to set up the lock after a lot of trial and error. Connecting the keypad however remains unsuccessful. It only says "cannot change location settings of the device" this eventhough I did grant the app the location permission. Edit: app now shows you are not allowed to access this smart lock? Contact administrstor. Terrible app. Waste of my time.

Such a great idea and totally reliable (in that, eventually, it always opens the door), yet just incredibly slow and inconsistent. Sometimes it opens everything straight away, sometimes you have to wait minutes(!) only to have the doors open when you're long inside. It's just so frustrating and ludicrous. Also, one has to restart the app regularly whenever the status can't load.

Hello Lennart, we are sorry you are unhappy with how your Smart Lock works. A delayed Auto Unlock is caused by the Smart Phone updating the location data too late. There is unfortunately nothing the Nuki App can do to change this behaviour as the App and the Smart Lock are just trying to trigger the Auto Unlock as soon as possible. -Nuki Team
