✓Editorial verdict
Which Should You Pick: Klevio or Operto Access?
Pick Klevio if you operate UK short-term rentals with existing analogue or electric intercoms (Paxton, BPT, URMET, Comelit, PAC GDX) and want to electrify the existing lock rather than replace it. Pick Operto Access if you run 15+ units across mixed lock brands and want one rental contract spanning Salto, Yale, August, Schlage, and Igloohome with curated PMS integrations through Hostaway, Guesty, Cloudbeds, or Hostfully.

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.

Try Operto AccessWhat each tool does well — and where it falls short
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 Operto Access does well
Broad smart-lock ecosystem under one platform
Operto's keyless-entry blog states 'Every lock below integrates with major PMS software and Operto's guest management and communication platform,' listing Salto KS, Yale, August, Schlage, and Igloohome as supported brands.
Reliability and support cited by verified reviewers
On Capterra, Gustavo S. writes 'very reliable and stable. Any time we need support we get prompt replies,' and Amanda M. notes 'Operto has great customer service for both onboarding and troubleshooting.'
Rental model reduces hardware capex
The Operto Access landing page is titled 'Rent Smart Devices & Lock Systems,' framing the product as a rental rather than a purchase — useful for operators expanding fleets without sinking $200+ per door.
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 Operto Access falls short
Opaque pricing blocks easy comparison
Operto's pricing page publishes no tiers and asks visitors to request a custom quote; Capterra reinforces this with 'Starting price: Contact vendor for pricing' and 'Free trial: Not available.' Operators cannot benchmark against Igloohome or RemoteLock without a sales call.
Support experience can be uneven at the tail end
While many reviewers praise support, Simon L. on Capterra writes 'Absolutely horrific customer support 12 days issue is still not fixed,' and Jaren B. reports the vendor 'just decided to discontinue operations one day without telling this customers.'
Thermostat integration is limited to Ecobee
Capterra review aggregation states 'Currently, Ecobee is the only thermostat Operto integrates with,' which constrains operators standardized on Nest, Honeywell, or other brands.
Which Should You Pick
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 Operto Access if
Multi-unit STR operators and boutique hotels who want a single access-control layer across multiple lock brands and already use a PMS Operto integrates with (Hostaway, Guesty, Cloudbeds, Hostfully).
Skip Operto Access if
You manage only 1-3 listings and want a one-time hardware purchase with a DIY codebook — Operto's rental subscription and sales-led pricing are overkill at that scale.
Where Klevio and Operto Access actually differ
- Klevio is a UK-specific retrofit that turns existing intercoms and locks into app-controlled access via mains-powered hardware; Operto Access doesn't make hardware and instead bundles five third-party lock brands (Salto KS, Yale, August, Schlage, Igloohome) under a sales-quoted rental subscription.
- Klevio is mains-powered with no batteries to manage across the portfolio; Operto's reliability profile depends on whichever battery-powered lock brand you deploy through the platform.
- Operto integrates with Hostaway, Guesty, Cloudbeds, and Hostfully for PMS-driven access automation; Klevio has no verified PMS or channel-manager integration and Capterra references an unspecified API with no public developer docs as of 2026-04-26.
- Both publish no list pricing — Klevio's pricing page returned HTTP 404 on 2026-04-26 and Operto's Capterra listing confirms 'Contact vendor for pricing' with no free trial — but Operto bundles broader operations (Ecobee thermostats, NoiseAware noise monitoring) under contract while Klevio is access-only.
- Klevio has essentially zero third-party review evidence (Capterra and GetApp both show 0 reviews); Operto has verified Capterra reviews praising stability and support, alongside concrete escalation complaints — limited social proof versus mixed but real signal.
Common objections
- Operto integrates with major PMS platforms and Klevio doesn't — isn't that a dealbreaker for any serious operator?
- For multi-channel operators who need access codes flowing automatically from reservations, yes — Operto's Hostaway/Guesty/Cloudbeds/Hostfully coverage solves a problem Klevio architecturally doesn't address today. Klevio's value is narrower and physical: electrifying UK intercoms and existing cylinders that you can't or won't replace. If your binding constraint is leased-flat door hardware or a listed-building intercom, Klevio is one of the few viable retrofits; if it's PMS-driven automation, Operto wins.
- Both vendors hide pricing behind a sales call — why pick the one with almost no third-party reviews?
- Honest answer: Klevio's review thinness is a real procurement risk and Operto has more verified Capterra signal — both positive (Gustavo S., Amanda M.) and negative (Simon L.'s 12-day support escalation). Klevio is a better choice only when its specific retrofit angle matters (UK intercoms, mains power, no cylinder swap). For everything else, Operto's documented track record across boutique hotels and multi-unit STR portfolios is the safer bet.
- Klevio is mains-powered with no batteries — doesn't that beat Operto's lock brands across the board?
- On battery management, yes — Klevio sidesteps a real failure mode that affects every battery-powered smart lock in Operto's supported list. But Operto's value isn't lock chemistry; it's PMS-driven automation across multiple brands plus optional Ecobee and NoiseAware integrations under one contract. If batteries are the binding pain and you operate UK properties with compatible intercoms, Klevio's mains-powered architecture is a genuine edge. Otherwise, Operto's broader operational scope outweighs the battery question.
