Smart Locks
Retrofit smart lock with native Airbnb integration
The right smart lock when you can't modify the door exterior
From $149.99 • No free trial
Pick Klevio if you operate UK short-term rentals with existing Paxton, BPT, URMET, Comelit, or PAC GDX intercoms you want to electrify rather than replace, and you can tolerate sales-quoted pricing. Pick August Home if you're a North American Airbnb-first host on ANSI deadbolts who can't modify the door exterior and want a reversible 10-minute retrofit with native Airbnb code automation at transparent USD pricing.
Editorial perspective from the Klevio side; factual claims about August Home are drawn from its review.

No public pricing. Klevio's pricing page returned HTTP 404 on 2026-04-26 and the support article 'How much does it cost?' directs buyers to sales for a quote based on their setup. A 2019 UK Airbnb promo (now ended) listed device+install at £549 RRP and £15/month over 24 months, but those numbers are not current.

What Klevio does well
Retrofits existing locks rather than replacing the cylinder
Klevio.com states the device 'transforms existing locks into ultra-effective smart locks,' which avoids the cost and landlord-permission hurdle of swapping hardware in leased UK flats.
Mains-powered hardware — no batteries to manage
Klevio's device-and-app page confirms the units 'are connected to mains power - no batteries involved,' eliminating a common failure mode for battery smart locks across a portfolio.
Remote 24/7 unlock and app-less guest access
GetApp's listing confirms users can 'lock / unlock your existing doors, from anywhere, 24/7' with an 'app-less access option,' which matters when guests refuse to install yet another app.
Pairs with Nuki for deadbolt-only doors
Klevio's support article confirms Nuki 'is a smart lock that we sometimes use to work alongside Klevio' for doors with deadbolt locks — extending the addressable property set.
What August Home does well
Non-invasive installation preserves original door appearance
August's retrofit design installs over an existing deadbolt without changing the exterior — SafeWise describes it as "perfect for rentals with HOA restrictions or landlord requirements" with a 10-minute install.
Native Airbnb integration automates guest access codes
Linking August and Airbnb accounts means the lock automatically generates a unique access code when a guest books, eliminating manual code management per The Connected Shop.
Works with every major smart home platform
August's official Works With page lists Amazon Alexa, Google Assistant, Apple HomeKit, Samsung SmartThings, IFTTT, SimpliSafe, Control4, and ecobee among supported integrations.
Keeps physical key functionality as a backup
The retrofit-over-deadbolt design means the original key still works — useful for owner access, maintenance, or when batteries die unexpectedly.
Where Klevio falls short
Pricing is gated behind a sales form
The /pricing URL 404s and the sales page asks buyers to 'Tell us about your use case so we can calculate the appropriate price' — making it hard to budget a portfolio rollout without a call.
iOS app reliability is patchy in user reviews
App Store reviews for the GB Klevio app flag that 'the app forces you to type in your account password every time you need to open a door' and 'key doesn't even swipe half the time,' against an overall 3.7/5 from just 22 ratings.
Third-party review evidence is essentially absent
Capterra shows 'Based on 0 user reviews' and GetApp shows 'Overall rating: 0/10 with 0 reviews,' so vendor claims about reliability and ROI are difficult to validate independently.
No verified PMS or channel-manager integration
Capterra mentions an unspecified API, but no public developer docs, Zapier listing, webhook documentation, or PMS partnership (Hostaway, Guesty, Lodgify, OwnerRez, Hospitable) was findable on klevio.com or help.klevio.com on 2026-04-26.
Where August Home falls short
Shorter battery life increases maintenance burden
Smart Home Perfected notes CR123 batteries last 3-6 months versus 9-12 for Yale or Schlage — a notable drawback when managing multiple properties at distance.
Keypad for backup access sold separately
The external keypad is a separate accessory at around $59, adding 25-40% to the effective per-door cost before shipping or installation.
Less proven for high-volume commercial rentals
RedAwning notes Yale Assure Lock 2 is deployed across 50,000+ RedAwning-managed properties with a 99.7% uptime rate, and recommends Yale or Schlage Encode Plus for high-traffic rentals.
No comprehensive public API documentation
Integrations are available through official partners and supported platforms, but August does not publish a documented public API — limiting custom PMS/automation integrations.
Pick Klevio if
UK short-term-rental hosts with existing analogue or electric intercom systems (Paxton, BPT, URMET, Comelit, PAC GDX) who want to electrify the existing lock rather than replace it.
Skip Klevio if
You operate outside the UK, want self-serve DIY pricing, or need a smart lock that integrates directly with your PMS or channel manager.
Pick August Home if
Properties with HOA restrictions or landlord requirements prohibiting exterior door modifications, where a reversible 10-minute install matters.
Skip August Home if
You run high-volume commercial properties and need maximum battery life and the most proven track record for smart-lock reliability.
