Best Smart Locks for European Holiday Rentals (2026)

Search "best smart locks for Airbnb" and you'll get a list of American deadbolts. Schlage Encode. Yale Assure Lock 2. August. Level Bolt.

None of them fit your door.

European doors run on euro-profile cylinders, the flat oval-and-circle shape you can see from the outside, usually paired with a multi-point mechanism that throws two or three bolts when you lift the handle. A US deadbolt retrofit has nothing to grab onto. So every guide ranking for that keyword is, for a host in Milan or Valencia or Rotterdam, twenty minutes of reading that ends in a product you can't buy.

The other half of the internet has the opposite problem. There are good euro-cylinder comparisons out there and they're written for people who live in the house. They test auto-unlock when you walk up with your phone in your pocket. Lovely feature. Completely irrelevant when the person at the door is a stranger from Osaka who landed 40 minutes ago and has no intention of installing your lock's app.

This guide is the overlap: euro-cylinder hardware, judged on whether it survives 60 guest turnovers a year.

Quick verdict

The best smart lock for a European holiday rental is the Nuki Smart Lock Pro (5th gen) at €269, paired with a Nuki Keypad. It fits your existing euro cylinder without drilling, has Wi-Fi built in, and connects to Airbnb to issue and expire guest codes automatically. Guests type a six-digit PIN and download nothing. Four picks depending on what you're optimising for:

Best overall — Nuki Smart Lock Pro (5th gen), €269 The only lock here where short-term rental is a designed-for use case rather than an afterthought. Native Airbnb sync sends the code, starts it at check-in time and kills it at checkout with no work from you. Wi-Fi is built in, so no bridge to buy. Add the keypad and budget €400 to €420 per door, which is the honest number most guides leave out.

Best value — Tedee GO, €164.90 (frequently €129) Under half the Nuki once discounted, smaller, quieter, and it fits narrow door reveals where the Nuki physically won't. The trade: Bluetooth only unless you add the bridge, and booking sync runs through PMS partners rather than a direct Airbnb link. Right for one or two doors where you're on site often enough that remote unlock isn't critical.

Best security — Bold Elite, €289 incl. VAT Replaces the whole cylinder with an SKG★★★ unit and removes the keyhole entirely, so there's nothing to pick, bump or core-pull. One CR123A battery quoted at three to eight years, against AAs every six weeks on motor-on-thumbturn locks. Worth it for ground-floor city apartments, or where your insurer specifies lock certification. Weaker on booking automation.

Best when you can't fit a lock — KeyNest, from £5.95 per collection For listed buildings, condominium boards that say no, landlord restrictions, or a shared street door you don't control. Keys sit at a partner shop or locker and the guest collects with a code. Break-even against a Nuki setup lands around 45 to 50 collections, so roughly a year at four turnovers a month.

Two situations that override all of the above. If your property's internet is unreliable, igloohome Deadbolt Go (€169) generates codes offline and doesn't care. And if guests have to get through a shared street door first, the Nuki Opener (€129) handles the intercom, which no amount of spending on the flat door will do.

The comparison

One lock per brand, chosen as the best fit for a rental rather than the flagship. Where a brand's wider range matters, the individual sections say so.

Separate from the table, because it isn't a door lock: the Nuki Opener (€129) wires into an existing intercom and handles the shared street door. It complements any lock here rather than competing with one, and it gets its own section below.

One thing to watch when you compare these yourself: LOQED quotes €299 excluding VAT while Bold quotes €289 including it. At Dutch VAT that puts LOQED north of €360 delivered, which is a €70-plus gap the sticker prices hide. European shops are inconsistent about this in a way US retailers aren't, and it's the single easiest way to get your budget wrong across a multi-property order.

Before you buy anything: measure your cylinder

This is the step that costs people money, and no US-focused guide will warn you about it.

Most retrofit locks (Nuki Go and Pro, Tedee, Yale Linus) mount on the inside thumbturn and physically rotate your existing key. That only works if your cylinder has an emergency function, meaning it turns from the inside even with a key left in the outside. Plenty of older Italian, Spanish and French cylinders don't. You'll need the cylinder swapped first, which is a €40 to €90 job plus a locksmith visit.

Second trap: cylinder length. Euro cylinders come in dozens of size combinations and yours probably isn't symmetrical. Bold sells the Elite in sizes like SX33 with separate indoor (max 35, 45, 55, 65mm) and outdoor (30-45, 50-65mm) measurements, and Nuki's Ultra includes its own cylinder. Measure from the centre screw hole to each face separately before ordering anything that replaces the cylinder outright.

Third: multi-point doors. Both Bold and Nuki work with many multi-point systems that use a euro cylinder, and "many" is doing real work in that sentence. If lifting the handle is what locks your door, the smart lock only turns the cylinder. Guests still have to lift the handle. Which they won't, because nobody outside Europe has ever seen a door that works this way, and your door will sit unlocked all week.

That last one isn't a hardware problem. It's an instructions problem, and we'll come back to it.

The picks

Nuki Smart Lock Pro (5th gen), €269 — best for most hosts

Austrian, shipping since 2015, and the only brand here that treats short-term rental as a first-class use case rather than an afterthought.

The thing that matters: Nuki connects to Airbnb directly through Nuki Web. Link your listing, and 72 hours before arrival (adjustable) your guest gets their keypad code through Airbnb's own messaging, in the language their Airbnb account is set to. The permission starts at your listed check-in time and deletes itself after checkout. Booking extended, the code follows. Booking cancelled, the code dies. Nuki Smart Hosting also connects to Smoobu, Guesty and a long list of PMS platforms, so you're not tied to Airbnb-only automation if you're building direct bookings.

Wi-Fi is built into the Pro, which is what makes it the host pick. Remote access is not optional in a rental. When a code fails at 23:00 you need to open the door from your sofa, and you need to see whether anyone actually got in.

Then the keypad, which is the part that makes any of this work for rentals, because it's what lets the guest in without an app. It's sold separately and it isn't cheap. The Keypad 2 NFC launched in March 2026 at $179 RRP in the US, and the older Keypad 2.0 sells around €150 to €170 in European shops. Whichever you pick, add it to the lock price before you decide anything. [CONFIRM CURRENT EU PRICE ON NUKI'S OWN STORE BEFORE PUBLISHING.]

Two other models exist if the Pro isn't the fit. The Go sits below it at €149, though confirm it reaches Nuki Web without extra hardware before ordering, since a hub would eat the saving. The Ultra at €349 is the smallest of the three and ships with its own security cylinder, which on an old door needing a cylinder swap anyway closes most of the price gap.

Skip it if: you're bothered by size. The Pro's housing is visible from inside the flat and guests in a design-led apartment will notice. Check which battery the model ships with, too. Where the motor rotates your key on every opening, AA cells under heavy turnover are the weak point and the rechargeable Power Pack is worth having.

Nuki Opener, €129 — the one nobody writes about

Almost every guide in this category, in both languages, stops at the flat door. Which means they solve the second door and ignore the first.

If you host in an Italian, Spanish or Portuguese city, your guest's actual problem is the portone: the street door with the intercom panel, twelve unlabelled buttons and a lock you don't control. Your beautiful smart lock is three floors up behind it.

The Opener wires into the existing intercom and lets you buzz the street door from the app, or lets the guest trigger it themselves. At €129 it's cheaper than the lock it complements, and for a first-floor-of-a-condominium listing it removes more guest friction than anything else on this page. Worth checking your intercom model against Nuki's compatibility list first, and worth a conversation with your building administrator, because you're touching shared infrastructure.

Tedee GO, €164.90 (often €129) — best value right now

Polish, noticeably smaller and quieter than the Nuki. If your door has a narrow reveal, a close-fitting handle plate, or 6cm of clearance to play with, Tedee often fits physically where Nuki doesn't. Installation runs about ten minutes.

At the promotional €129 it's the cheapest credible euro-cylinder lock here, well under half the Nuki Pro. The catch is that the base GO is Bluetooth only. No bridge means no remote access, so no remote unlock and no visibility into arrivals. Add the bridge and the price advantage narrows.

Skip it if: you want booking sync out of the box. Tedee reaches short-term rental platforms through partners rather than a direct Airbnb link, so check your specific PMS is supported before buying.

Yale Linus L2, from €239.99 — best for guest recognition

Yale has been on European front doors for over a century and that counts for something in a listing photo. The L2 keeps your original cylinder and has Bluetooth and Wi-Fi built in, so remote access needs no extra box. The Yale Smart Keypad handles PIN entry and is sold separately.

It's the safe institutional choice and it's the one I'd argue least hard for. On the criteria that matter in a rental, automatic code generation from bookings and expiry after checkout, it trails Nuki. At €239.99 you're within €30 of the Nuki Pro, and part of what you're paying for is the badge.

Skip it if: you're automating across more than a couple of properties.

SwitchBot Lock Pro, €139.99 — cheapest way to find out if you like this

List price is €139.99 and SwitchBot runs aggressive discounts, frequently 30% off with a code, which brings it under €100. It works, it fits euro cylinders with the right mount, and the keypad bundles do fingerprints.

It's a hub-dependent consumer smart home product rather than a hosting tool. No native booking integration, so you're rotating codes by hand or through a middle layer. Fine for one property. Miserable at five.

Skip it if: you have more than two doors, or check-ins are already what eats your week.

Bold Elite, €289 — best if security is the actual concern

Dutch, and the only pick here that removes the keyhole entirely. Bold replaces the whole cylinder with an SKG★★★ certified unit, so there's nothing to pick, bump or core-pull from outside. €289 including VAT and including the cylinder, sized to your door, and the single CR123A battery is quoted at three to eight years. Against changing AAs every six weeks, that's a different ownership experience rather than a spec-sheet win.

Worth taking seriously for a ground-floor city apartment, or if your insurer has opinions about lock certification, which some European policies do.

Skip it if: you need deep booking automation, or you can't get the sizing exactly right.

LOQED Touch, €299 excl. VAT — best for Dutch and Belgian hosts

Touch-to-open on the housing, Thread support, cylinder included, and a Dutch company answering the phone in your timezone. Read the price carefully: €299 is quoted excluding VAT, so the delivered cost lands well above Bold and above the Nuki Pro. In the Netherlands or Flanders, local support earns some of that back. Elsewhere it's hard to justify against Nuki.

igloohome Deadbolt Go, €169 — best for properties with bad internet

Different design philosophy. igloohome generates codes algorithmically and offline, with no internet connection at the lock at all. You create a PIN in the app, the lock computes independently whether that PIN is valid for that window, and it opens.

For a mountain cabin, a rural finca, or anywhere the router drops for three days after a storm, this is the correct answer. The Deadbolt Go at €169 is the value pick of their range; the line runs up through the Deadbolt 2S and the Mortise models to €449.99 if you need heavier hardware. European pricing sits well above the US figures other guides quote, so don't budget from an American review.

Skip it if: you want remote unlock or a live activity log. You get neither. And you still need mobile signal on your phone to generate a code, so no internet plus no cell coverage puts you back on a mechanical lockbox.

KeyNest, from £5.95 — when you can't fit a lock at all

Plenty of European hosts simply can't. The condominium board says no. The building is listed. Your landlord says no. Or the street door has a shared lock you don't control, so a smart lock on the flat door solves half the problem.

KeyNest holds your keys at a partner shop, café or automated locker. Guest arrives, shows a code, collects. Founded by two Airbnb hosts in London in 2016, now the largest network of its kind across the UK, much of Europe and beyond. Pay-as-you-go starts at £5.95, with unlimited plans for hosts turning over constantly. If you're running enough volume in one building, KeyNest also sells you your own locker from £1,099, which changes the maths again for an aparthotel or a block of six units.

The break-even against hardware: a Nuki Pro plus keypad at roughly €420 pays for itself somewhere around 45 to 50 key collections. At four turnovers a month that's about a year. A discounted Tedee or SwitchBot setup gets there in half the time.

One thing hosts underestimate: shop opening hours. Keycafe's 24/7 automated lockers matter more than the price difference when your guest lands at 23:40 and the café closed at 19:00.

The code is not the check-in

Here's the pattern we see in GuestIntro accounts, and it's why a lock alone doesn't fix arrivals.

Hosts install the lock, wire up the Airbnb integration, watch the code send automatically, and think check-in is solved. Then the messages keep coming. The code opens a door. The guest's actual problem is the sequence before it.

Which of the three street doors on this block. The building code, which is different from the flat code. Whether the lift needs a fob. Which floor, given the Italian ground floor is zero. That the handle has to be lifted before the lock engages. Where the bins are, because they'll ask on day two regardless.

None of that is in the lock's automated message, and it's the same seven questions every single time. A digital guest manual holds the arrival sequence with photos of the actual doors, auto-translates for the guest who booked from Japan, and updates for every past and future guest the moment you change the WiFi password. Hosts pair it with the lock rather than instead of it. Our guest manual examples show how the arrival section is usually laid out.

One small thing worth doing the same afternoon you install the lock: generate a WiFi QR code and stick it inside the door. The two questions that arrive within four minutes of entry are always the door and the WiFi. Solve both at the threshold and your inbox goes quiet.

How to choose

One property, testing the idea: SwitchBot Lock Pro on a discount, or Tedee GO at €129.

One to five properties on Airbnb and Booking.com: Nuki Smart Lock Pro plus Keypad. The native booking integration is the whole reason.

City apartment behind a shared street door: whichever lock suits, plus the Nuki Opener at €129.

Rural, weak internet: igloohome Deadbolt Go.

Ground floor, insurance conditions: Bold Elite.

Building or landlord says no: KeyNest, plus a manual explaining exactly which shop and what to say when they get there.

Questions hosts ask

Do smart locks work on European multi-point doors? Often, but not automatically. Nuki and Bold both support many multi-point systems using a euro cylinder. The lock turns the cylinder; it doesn't lift the handle. On doors where lifting the handle engages the bolts, the guest has to do that themselves, so it has to be spelled out in your arrival instructions or the door stays effectively unlocked.

Can Airbnb send guest codes automatically? Yes, on supported hardware. Nuki links to Airbnb through Nuki Web and sends codes via Airbnb's own messaging, expiring them after checkout. Schlage has an equivalent Airbnb integration, though it's US and Canada only and won't fit a European door. Most other locks route through a PMS instead.

What about the building's street door? A smart lock on your flat door does nothing for the shared entrance. The Nuki Opener (€129) wires into an existing intercom and handles it. Check your intercom model against the compatibility list, and clear it with your building administrator first.

What happens if the WiFi drops during a stay? Keypad codes on most locks are stored on the device, so entry keeps working. What you lose is remote unlock, live logs, and the ability to issue a new code mid-stay. If that's likely, igloohome's offline model removes the risk entirely.

Is a smart lock cheaper than a key exchange service? Past roughly 45 to 50 collections, yes. At £5.95 and up per collection, a host doing four turnovers a month reaches the cost of a Nuki Pro and keypad in about a year, and after that the hardware is free. A discounted Tedee or SwitchBot setup breaks even in roughly half that.
