Nuki Smart Lock Go(5th Gen)

Nuki Smart Lock Go (5th Gen) — Retrofit Bluetooth smart lock that adds keyless entry to your existing deadbolt without replacing the cylinder.

The Nuki Smart Lock Go (5th Gen) fits over your existing euro-profile lock cylinder on the inside of the door, converting it to a smart lock without any locksmith work. Control the lock via the Nuki app on iOS or Android using Bluetooth. For remote access and smart home integration — Apple HomeKit, Amazon Alexa, or Google Assistant — the Nuki Bridge (sold separately) provides the Wi-Fi gateway. Access logs record all lock and unlock events. Time-limited access codes can be issued to guests or service providers without handing over physical keys. Compatible with most standard European door locks.
