Overview
Mounting the Nuki Smart Lock over your existing deadbolt turns the inside thumb turn into a motorized, app controlled lock. A wireless keypad outside adds code, fingerprint and NFC entry, with no drilling or wiring needed.
Access options are the strongest case for it: phone, fingerprint, code, NFC, digital home keys and auto unlock all work from one setup. Matter over Thread support ties it into most smart home platforms. The listing does not spell out which deadbolt designs it fits, which is the key question for renters and older doors.
Who it's for
Families, Airbnb hosts and shared homes managing many codes and fingerprints. People with mortise locks or unusual deadbolts should confirm fit before buying.
Pros and cons
- No drilling or wiring
- Many entry methods including fingerprint
- Large code and fingerprint capacity
- Works across major smart home platforms
- Deadbolt compatibility list not provided
- Keypad adhesive may loosen on rough surfaces
- Charging cycle length unstated
Performance notes
Reliability depends on how freely the deadbolt turns, since the motor drives the existing thumb turn. Thread and Wi-Fi links keep remote control and automations responsive, while Bluetooth handles nearby phone unlocking. Keypad placement affects range to the lock.
