Nuki Smart Lock Review: Retrofit Locks for STRs (2026)
Overview
Nuki offers retrofit smart locks (Smart Lock Go, Pro 4th Gen, Ultra) optimized for vacation rentals via its Smart Hosting service (€69/year per lock). The locks support app unlock, keypad PINs, Matter/Thread, and PMS integrations (Airbnb, Smoobu, Uplisting, etc.) for automatic per‑reservation codes.
- Hardware starts at €120–€289 plus optional Bridge/Keypad (€69–€99), making it renter‑friendly with no door drilling, though full remote access requires the subscription.
At a glance
- Smart Hosting service (€69/year per lock) auto‑syncs Airbnb/Smoobu/Uplisting bookings to generate guest PINs/key shares, with 30‑day free trial.
- Retrofit design installs in minutes without drilling on most European cylinders (Smart Lock Go/Pro); Pro 4th Gen has built‑in WiFi/Thread for Matter without Bridge.
- Multiple unlock options: app, keypad PINs, NFC key fobs, Apple Watch, Alexa, fingerprint (Keypad 2), plus Auto Unlock geofencing.
- Property managers and teams
- Hosts who want a clean UI
- Automation-first workflows
- Smart Hosting subscription (€69/year per lock) required for PMS/OTA auto‑codes and remote access; basic Bluetooth works offline but lacks remote features.
- Retrofit only fits specific cylinder types (European standard); US/UK deadbolts may need adapters or other models.
