Why Smart Locks for Airbnb?
Traditional key handovers are the single biggest friction point in short-term rentals. You either need to be physically present, hide a key in a lockbox (which feels sketchy to guests), or pay someone to do the handover. None of these scale.
With a smart lock, guests let themselves in. No coordination, no waiting, no awkward phone calls at midnight when their flight was delayed. You generate a unique code, send it in the Airbnb message thread, and you're done. Your guests get a smoother check-in experience, and you get your evenings back.
The impact on reviews is real. Self-check-in is one of the top-rated features on Airbnb. Hosts who switch to keyless entry consistently report better review scores — not because the lock itself is exciting, but because removing friction at arrival sets the tone for the entire stay.
Setting Up Nuki for Guests
The Nuki app lets you create time-limited access for each guest. You set the check-in date and time (say, 3:00 PM on Friday) and the check-out date and time (11:00 AM on Sunday). The code or app access only works during that exact window.
You can share access in three ways: send the guest a PIN code for the Keypad 2, invite them through the Nuki app, or generate a web link they can open on any phone without installing anything. For Airbnb, the PIN code method is by far the most popular because it requires zero setup on the guest's end.
Each guest gets their own unique code. After check-out, that code stops working automatically. You never need to change locks, reset codes, or worry about previous guests still having access. The system manages it all.
Keypad 2 — The Game Changer
The Nuki Keypad 2 NFC is what makes this setup truly hands-free. It mounts next to your door and lets guests enter a 6-digit PIN code to unlock — no phone, no app, no Bluetooth pairing.
This matters more than you might think. International guests often arrive without mobile data. Older guests might not be comfortable with apps. And anyone who's ever tried to explain Bluetooth pairing to a tired traveler at 11 PM knows it's not a great experience. The Keypad removes all of that. Code in, door opens.
The Keypad 2 NFC also supports fingerprint access, which is useful for cleaners or co-hosts who visit regularly. You can store up to 20 fingerprints alongside 200 PIN codes — more than enough for even the busiest property.
Auto Unlock & Auto Lock
Nuki's Auto Lock feature is a lifesaver for hosts. Set it to lock the door automatically after 20 seconds (or whatever interval you prefer), and you'll never get that dreaded message: "We left but forgot to lock up."
This is especially important for properties in apartment buildings where an unlocked door is a security concern for neighbors too. The door locks itself behind guests every single time — whether they're stepping out for groceries or checking out for good.
You can also enable the "Lock 'n' Go" feature, which lets guests lock the door by pressing a single button on the Keypad as they leave. Combined with Auto Lock, your property is secure without guests needing to think about it.
Managing Multiple Properties
If you manage more than one Airbnb, Nuki scales with you. Every lock appears in the same app, and you can create guest access, view the activity log, and manage settings for all properties from your phone or the Nuki Web interface.
The activity log is particularly useful for multi-property hosts. You can see exactly when each guest arrived and left, which helps with cleaning schedules and resolving disputes. If a guest claims they checked out on time but the cleaner found the place trashed at 4 PM, the log tells the real story.
For property managers with 5+ units, the Nuki Web dashboard (web.nuki.io) provides a desktop view of all your locks, access codes, and activity — much faster than managing everything from a phone.
Cost vs Savings
A Nuki Smart Lock Pro (4th Gen) costs around €199, and the Keypad 2 NFC adds another €79. That's roughly €280 per property. It sounds like a lot until you do the math on what you're spending now.
A single locksmith call for a lost key runs €80–€150 in most European cities. One key replacement per year already covers half the cost. Factor in the time you spend on key handovers — even 15 minutes per guest, at 3 guests per week, that's nearly 40 hours per year. What's your time worth?
Then there's the review effect. Better check-in experiences lead to better reviews. Better reviews lead to higher search ranking on Airbnb. Higher ranking leads to more bookings. The lock doesn't just save you hassle — it quietly drives more revenue.
Most hosts report that the Nuki pays for itself within 2–3 months of active hosting.
