✓Editorial verdict
Which Should You Pick: Klevio or Sifely?
Pick Klevio if you operate UK short-term rentals with existing analogue or electric intercoms (Paxton, BPT, URMET, Comelit, PAC GDX) and want a mains-powered retrofit that electrifies the existing lock. Pick Sifely if you want the lowest per-door hardware cost ($79.99 starting) with five unlock methods including fingerprint and fob, plus direct Auto Booking Code automation for Airbnb, Guesty, and Hostaway.

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 SifelyWhat 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 Sifely does well
Auto Booking Code pulls reservation data and generates time-limited passcodes automatically
The feature integrates with Airbnb, Guesty, Hostaway, and other platforms to create guest codes without manual entry — a meaningful time-saver at 5+ properties.
Five unlock methods give guests multiple fallback options
Fingerprint, code, fob, smartphone, and physical key mean a single failure mode rarely locks a guest out entirely. The reversible handle simplifies installation on any door.
Configurable auto-lock prevents the common STR problem of unsecured doors
The lock re-engages after a set delay, removing reliance on guests remembering to lock up — a frequent pain point flagged in STR operator forums.
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 Sifely falls short
Touchpad responsiveness is inconsistent, working roughly 90% of the time
User reviews report intermittent touchpad failures. For high-turnover STRs where every check-in matters, a 10% failure rate creates real guest friction and support burden.
Remote management requires purchasing a separate WiFi gateway
The base lock is Bluetooth-only. Remote code management — the core value for multi-property hosts — is locked behind an additional hardware purchase at undisclosed pricing.
Fingerprint scanner reliability is a recurring user complaint
Reports describe the scanner reading correctly (green light) but failing to unlock. For hosts relying on biometric access as the primary unlock method, this undermines the convenience promise.
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 Sifely if
STR hosts managing multiple properties who need automated passcode generation tied to booking platforms like Airbnb, Guesty, or Hostaway — and want to avoid monthly lock software fees.
Skip Sifely if
You need guaranteed 24/7 hardware reliability for high-turnover properties, require integrations with PMS platforms beyond the currently supported list, or need enterprise-grade remote fleet management.
Where Klevio and Sifely actually differ
- Sifely is a one-time hardware purchase starting at $79.99 per lock with verified USD pricing on the vendor shop page; Klevio's pricing page returned HTTP 404 on 2026-04-26 and every buyer must complete a sales form for a quote.
- Sifely's Auto Booking Code natively integrates with Airbnb, Guesty, and Hostaway for auto-generated per-reservation passcodes; Klevio has no verified PMS or channel-manager integration as of 2026-04-26.
- Klevio is a UK-specific retrofit for existing locks and analogue/electric intercoms (Paxton, BPT, URMET, Comelit, PAC GDX); Sifely is a full lock replacement built for US-standard door preparations with a reversible handle for left/right-hand configurations.
- Klevio is mains-powered with no batteries to manage; Sifely is Bluetooth-first and battery-powered, with a separately purchased WiFi gateway required per property for remote code management.
- Sifely offers five unlock methods (fingerprint, code, fob, smartphone, physical key) but has a reported ~10% touchpad failure rate and fingerprint read-but-fail issues; Klevio's documented unlock options are app-based plus an app-less access option, with no biometric or fob support — and Capterra/GetApp both show 0 user reviews.
Common objections
- Sifely is $79.99 with no monthly fees and Klevio hides pricing behind a sales form — why even consider Klevio?
- For most operators, Sifely's economics are genuinely better and Klevio is hard to justify. Klevio earns its keep only when its specific retrofit angle matters — UK properties with existing Paxton/BPT/URMET/Comelit intercoms you can't replace, leased flats where freeholder rules forbid cylinder swaps, or operators who specifically want mains-powered hardware. Sifely doesn't physically fit those UK intercom scenarios at all. Outside that narrow retrofit case, Sifely's transparent pricing and direct PMS automation win.
- Klevio is mains-powered — doesn't that beat Sifely's battery-powered design?
- On battery management, yes — Klevio's mains-powered architecture genuinely sidesteps a real failure mode for battery smart locks across a portfolio. The honest trade-off is that Klevio's iOS app reviews flag forced re-auth on every door open and unreliable swipe-to-unlock against a 3.7/5 average from just 22 ratings — software reliability concerns. Sifely's failure mode is hardware (touchpad, fingerprint) with four other unlock methods as fallback at the door. Klevio sidesteps batteries but trades them for app-side friction; Sifely has more unlock redundancy when individual mechanisms fail.
- Sifely integrates natively with Airbnb, Guesty, and Hostaway — isn't Klevio's lack of any PMS integration a dealbreaker?
- For multi-property operators who need automated per-reservation codes, yes — Sifely's Auto Booking Code solves a problem Klevio architecturally doesn't address today. No verified Hostaway/Guesty/Lodgify/OwnerRez integration was found on klevio.com or help.klevio.com as of 2026-04-26, and Capterra references an unspecified API with no public developer docs. Klevio's value is physical retrofitting of UK intercoms; Sifely's is workflow automation at the lowest hardware cost in the category. Different problems, different right answers.
