Nuki Smart Lock Pro Review: The Premium Retrofit Lock With Built-In Wi-Fi
Easy retrofit install, integrated Wi-Fi (no paid add-on) and a fast rechargeable motor, at a premium price.
The Nuki Smart Lock Pro (2025) is the premium version of Nuki's retrofit smart lock, and its key advantage over the cheaper Go is built-in Wi-Fi, so remote access works out of the box with no paid add-on. It installs in minutes over a European cylinder with no cylinder change, has a strong, fast motor and a rechargeable battery, and offers auto-lock, hands-free auto-unlock and Matter/HomeKit/Google/Alexa/SmartThings support. The main downsides are the high price (more so with the keypad accessory) and isolated battery/reliability complaints.

Who is the Nuki Smart Lock Pro for?
This is Nuki's premium retrofit smart lock for European-style doors, mounting over the existing euro-cylinder with no cylinder replacement or drilling, so it suits renters and owners alike. The Pro's defining feature is integrated Wi-Fi, meaning remote control and smart-home access work without buying a separate bridge or unlock add-on (the main frustration with the cheaper Go). It supports Bluetooth, Matter (over Thread), Apple HomeKit, Google Home, Alexa, SmartThings and Home Assistant, with auto-lock after the door closes and geolocation auto-unlock. It uses a rechargeable built-in battery, and keypad/fingerprint entry are separate accessories. It best suits people who want Nuki's convenience plus full remote/smart-home control built in.
What buyers love
Install ease and the built-in Wi-Fi are the highlights. Owners describe mounting and app setup as fast and fuss-free, and those who previously had the Go specifically praise the Pro for including Wi-Fi rather than charging extra for it. The motor is called strong and quick, the rechargeable battery charges fast and lasts a long time, and hands-free auto-unlock as you approach (plus auto-lock when you leave) is the convenience people value most, especially arriving with full hands. The app is intuitive with good access management and real-time notifications, the build quality and compact design feel premium, and it integrates cleanly with smart-home systems and voice assistants. Long-time Nuki users note this generation is noticeably faster than older models.
What to know before you buy
The main caveat is price: it is expensive on its own and considerably more once you add the keypad with fingerprint (owners cite around 400 euros for the full setup). There are a few reliability complaints, including a battery that stopped charging after about six months and a unit with problems after four months, though Nuki's support is generally responsive. Installation has requirements to check first: your cylinder must protrude a few millimeters, the key must be operable from both sides, and a very long key may need trimming to fit. It is not weather-resistant, and passcode/fingerprint entry needs the separate keypad accessory. As with the Go, it is a retrofit for European cylinders, not US deadbolts.
Is the Nuki Smart Lock Pro worth it?
For European households wanting a polished, retrofit smart lock with full remote control built in, yes, it earns a good average rating and the integrated Wi-Fi, rechargeable battery and fast motor make it the more complete choice over the Go (and avoid that model's paid add-ons). The convenience of hands-free entry is excellent. Just be ready for the premium price, especially with the keypad, confirm your cylinder/key meet the fit requirements, and note a few battery/reliability reports. Within its niche it is a strong, capable lock.
Frequently asked questions
What is the difference between the Nuki Pro and the Go?
The Pro has built-in Wi-Fi and a rechargeable battery, so remote/smart-home access works out of the box. The cheaper Go requires a paid add-on for Wi-Fi/remote access and uses AA batteries. The Pro is the more complete, higher-end option.
Does it need a separate bridge for remote access?
No. Unlike the Go, the Pro has Wi-Fi built in, so you can control it remotely and integrate it with smart-home systems without buying a bridge or unlock add-on.
Is it a retrofit, and will it fit my door?
It is a retrofit for European-style doors with a euro-cylinder, mounted inside over your existing cylinder. Check that the cylinder protrudes a few millimeters, the key works from both sides, and the key is not too long (it may need trimming). It is not for US deadbolts.
Does it have a keypad or fingerprint reader?
Not built in. Passcode and fingerprint entry require Nuki's separate Keypad accessory, which adds significantly to the cost. On its own it uses Bluetooth, auto-unlock, the app and your physical key.
How is the battery?
It uses a rechargeable built-in battery (Power Pack) rated around six months per charge, which owners say recharges quickly and lasts well. A small number reported the battery failing to charge after several months, handled through Nuki support.
