Overview
Nuki makes this compact smart lock to fit over your existing deadbolt on the inside of the door, with no drilling. It connects by Wi-Fi, Bluetooth and Matter over Thread, so the app, voice assistants and auto-unlock can all turn the bolt.
Wide smart home support and remote access come without touching the exterior hardware, which suits renters. Entry still needs a phone or key, since a keypad is not part of this box.
Who it's for
Rentals, apartments and short-term rental hosts benefit from a lock that installs without drilling and shares digital keys. Households where kids or guests have no phone will want a keypad too.
Pros and cons
- No drilling or exterior change
- Works with major smart home platforms
- Auto-unlock as you arrive
- Shares digital keys and logs activity
- No keypad in the box
- Deadbolt compatibility details not listed
- Battery needs regular recharging
Performance notes
The unit grips the inside thumb turn and rotates it with a motor, so the outside cylinder and key are unchanged. Wi-Fi gives remote control, while Bluetooth handles nearby phones for auto-unlock. Battery life is listed in months, so recharging becomes routine.
