33 Lock Review: Smart Locks for Hotels & Vacation Rentals (2026)
Overview
33 Lock is a hospitality‑focused smart‑lock brand aimed at hotels, motels, multifamily and vacation rentals. Its IntelliBolt, IntelliLever, IntelliMortise and IntelliReader locks provide PIN, card, and mobile access with retrofit‑friendly hardware that works with PMS, access‑control platforms, and APIs like Seam.
- It’s especially appealing if you want hotel‑grade hardware at lower cost and deep automation, but it relies on TTLock gateways and integrations for remote control and is less plug‑and‑play than consumer locks.
At a glance
- Built specifically for hospitality and multifamily—covering hotels, motels, hostels, resorts, vacation rentals and apartments—rather than retrofitting consumer locks into pro use.
- Retrofit‑friendly hardware (IntelliBolt, IntelliLever, IntelliMortise, IntelliReader) that installs on most existing doors without rewiring or major door modifications.
- Multiple unlock methods per lock—PIN codes, RFID cards, mobile access, plus physical key override—so operators can mix and match according to property or guest preference.
- Property managers and teams
- Hosts who want a clean UI
- Automation-first workflows
- Requires TTLock app and compatible TTLock gateway for remote control, adding a configuration layer versus Wi‑Fi‑native consumer locks.
- Public pricing is not listed; case studies emphasize “about half the cost of competitors” but you must request a quote for concrete numbers.
Pros & Cons
Highlights and considerations for 33 Lock.
- Built specifically for hospitality and multifamily—covering hotels, motels, hostels, resorts, vacation rentals and apartments—rather than retrofitting consumer locks into pro use.
- Retrofit‑friendly hardware (IntelliBolt, IntelliLever, IntelliMortise, IntelliReader) that installs on most existing doors without rewiring or major door modifications.
- Multiple unlock methods per lock—PIN codes, RFID cards, mobile access, plus physical key override—so operators can mix and match according to property or guest preference.
- Designed for portfolio‑wide management: centralized control of rooms and shared spaces, time‑bound access for staff and guests, and one system across multiple buildings.
- Works with automation platforms like HelloShift and SuiteOp, and can be controlled via the Seam API, enabling automatic, per‑reservation PIN codes and fully contactless check‑in/out.
- Requires TTLock app and compatible TTLock gateway for remote control, adding a configuration layer versus Wi‑Fi‑native consumer locks.
- Public pricing is not listed; case studies emphasize “about half the cost of competitors” but you must request a quote for concrete numbers.
- Targeted at hotels and larger portfolios; overkill if you’re just equipping one or two standalone STR units and don’t need multi‑building control.
- You’ll usually use 33 Lock via an intermediary platform (PMS, SuiteOp, HelloShift, Seam) rather than a first‑party STR app, which adds complexity.
- No built‑in dynamic pricing or messaging; it’s pure access control and depends on your PMS/automation stack for workflows.
Scores
Strong in / OTA sync and value for money; weaker in setup.
Hands-on Review Notes
Pricing
| Plan | Monthly | Base includes |
|---|---|---|
| Hardware (Locks & Readers) | No public MSRP; case‑study partners report 33 Lock came in at “nearly half the cost of comparable locks,” but specific per‑door pricing requires a quote. | IntelliBolt, IntelliLever, IntelliMortise and IntelliReader devices with integrated keypads; hospitality‑grade housings; support for PIN, card and mobile credentials; retrofit‑oriented installation. |
| Access Control via Integrators / APIs | Billed by the partner platform (e.g., HelloShift, SuiteOp) on a per‑room or per‑door basis; 33 Lock itself does not advertise direct SaaS pricing. | Cloud control, code management, logs and automations typically come from integrated platforms (HelloShift, Seam‑based apps, SuiteOp, PMS vendors) rather than a direct 33 Lock SaaS fee. |
