The new Nuki Smart Lock Pro 5th Generation nails the balance between sleek styling and practical functionality. Instead of the chunky look of older models, this retrofit-friendly lock presents a slim, circular stainless steel housing that blends seamlessly with most doors. You’ll barely notice it’s a smart device until the LED ring softly glows to show lock status. Plus, two interchangeable base rings—black and white—let you match your door’s aesthetics without breaking a sweat.
Under its minimalist exterior, the Pro model packs the same whisper-quiet brushless motor found in Nuki’s top-of-the-line Ultra version. By switching to an internal lithium-ion battery, Nuki shrunk the overall size and ditched those bulky AA battery compartments. The result? A lock that feels custom-built and refined, yet still compact enough not to draw attention. Recharging is equally intuitive via a magnetic USB-C cable that clips right under the handle—no tools or disassembly required.
Quick and Easy Installation
One of the biggest perks of the Smart Lock Pro is how fast and painless it is to set up. In under five minutes, you can attach the lock directly to your existing cylinder—no drilling, no heavy lifting. The package includes two mounting plates: one with adhesive backing and another with screws and an Allen key. Whether you’re a renter or a homeowner, the Pro fits right on and comes off just as easily when needed.
Once the plate’s in place, pop your key into the internal cylinder and slide the Smart Lock Pro over it. That’s it—no hardwiring or extra wiring. The app takes over next, guiding you through an automatic calibration so the lock learns exactly how many turns your door requires. You can even add optional accessories like an external keypad or a door sensor during this final step, though they’re sold separately. After pairing with Wi-Fi or Matter, remote control and voice commands are ready to go.
Intuitive and Customizable Use
Thanks to Nuki’s polished app, using the Smart Lock Pro feels like second nature. The speedy brushless motor unlocks or locks your door in just 1.5 to 2 seconds—three times faster than previous generations. Choose between three performance modes in the app: Standard for a solid balance of speed and smoothness; Insane for near-instant action; or Gentle if your door mechanism needs a softer touch or you simply prefer quieter operation.
Beyond your smartphone, you’ve got plenty of other ways to get inside. Stick to classic key entry from the outside if your cylinder is the escapable type, or use your phone via Bluetooth and Wi-Fi for local or remote control. The app also supports geofencing, so your lock can sense your arrival and let you in automatically. Apple Watch fans will appreciate the companion app, and voice control works flawlessly with Alexa, Google Assistant, or HomeKit through Matter. For code-based entry, consider the Keypad 2.0 or Nuki Fob accessories to provide PINs or fingerprint access without relying on a phone.
Long-lasting Battery and Simple Charging
Wave goodbye to disposable batteries. The Pro’s integrated lithium-ion pack promises up to six months of typical usage on a single charge. During initial tests, we saw only a slight drop after weeks of daily cycles. The lock’s battery status is always visible in the app, so you’ll get timely low-power alerts before it becomes critical. When it’s time to top up, clip the magnetic USB-C cable underneath—no removal necessary—and power from a portable charger or standard adapter (not included).
A full recharge takes about two hours, and the lock remains fully functional while charging. If you’d rather never worry about downtime, Nuki offers an optional power adapter that keeps the device plugged in constantly—trade a discreet installation for permanent power. Either way, regular charging becomes a routine you won’t mind, especially given how much better it is than swapping out four AA batteries every few months.
Rock-solid Security You Can Trust
Security is at the heart of any smart lock, and Nuki delivers with bank-grade encryption and local-first data handling. All communication between your phone, the lock, and any cloud services is protected by AES-256 with challenge-response authentication. Even if someone intercepts the signal, the lack of a valid cryptographic key ensures no unauthorized entry. You can also choose to keep all your access logs and settings local, bypassing cloud servers entirely unless you opt into remote control or voice assistant features.
The physical build contributes to security, too. The lock resides on the inside of your door, hidden from would-be vandals. Its solid steel housing and secure mounting plate make it nearly impossible to tamper with from outside. For extra peace of mind, the Nuki app sends notifications if it detects unusual activity, like a forced entry or your door left ajar. Independent security audits and AV-TEST certifications further prove that Nuki stays ahead of vulnerabilities and firmware updates keep your system safe over time.
Price and Availability
The Nuki Smart Lock Pro 5th Generation retails for €269 on Nuki’s official website, making it a competitive choice in the premium smart-lock market. If you want a keypad for key-free entry, bundle it with the Keypad 2.0 for €359, or opt for the keypad plus a door sensor package at €419. Accessories like the Nuki Fob remote or optional power adapter are available separately.
With fast shipping across Europe and growing availability in North America, the Pro model is an excellent entry point for anyone wanting Ultra-level performance without swapping out their entire cylinder. In short, if you’re after a seamless blend of design, speed, and security—without the hassle of a major retrofit—the Nuki Smart Lock Pro 5th Gen is hard to beat.
