I use this app and Smart Lock for my business and it's great. It's user friendly to set up and I can schedule it to lock and unlock my door. The door sensor is very reliable. It would be nice to have a door closer option so that I only get one notification per entry. But I realize for most people that is not a problem. Edited summer 2026 to say that after 5 years I am still very satisfied with the app and the hardware. Would buy again. Highly recommended!

I'm super annoyed by this app lately. The battery low notifications are never showing up. I had to call the locksmith once already. I'm really happy to still have a nuki with replaceable batteries so I could put in new ones with longer battery life again. Why are the devices not showing low battery status better as well...

Nuki is a truly great product that delivers top-tier reliability. Initial setup and configuration can be a bit complex, especially when fine-tuning remote access, Opener integration, and permissions. However, once everything is configured properly, it works flawlessly! ​The Keypad 2.0 works seamlessly via Bluetooth even if remote connection fluctuates, and all logs/activities sync automatically. Managing guest codes and remote access for rental properties gives great peace of mind. Highly rec.
