33 Lock integration

Hospitality-built deadbolts, reservation-driven codes.

33 Lock built a deadbolt for turnover. ProhostAI supplies the turnover.

Connect your 33 Lock account once and ProhostAI syncs every deadbolt to the reservation calendar — a fresh code per stay, delivered before arrival, expired after checkout.

Overview

33 Lock designs smart deadbolts for hospitality — hotels, motels and rentals — which means the hardware assumes what residential locks do not: a new guest every few days, forever. Codes, cards and phone entry on the lock, a metal key as backup, and pricing meant for outfitting whole properties rather than one front door.

A lock that expects turnover still needs something to feed it the turnover. ProhostAI is that feed: connect your 33 Lock account, assign each deadbolt to its listing, and every reservation becomes a door code with a validity window built from the stay — active shortly before check-in, removed after checkout, reshaped whenever the dates move.

The guest side is automatic. A template variable drops the code into scheduled check-in messages and the digital guidebook, and where the lock supports it the code is the last four digits of the guest’s phone number. If it still goes missing mid-stay, your AI employee can look the code up or unlock the door on request — audited, rate-limited, and never for a cancelled or past booking.

Across a hallway of doors, the accounting matters as much as the access: each device keeps a timeline of unlocks, code changes and failures, and any code that fails to set is surfaced for action instead of discovered by a guest holding luggage.

What ProhostAI can do with 33 Lock

Once your 33 Lock account is connected and deadbolts are assigned to listings, this runs on its own:

Guest access

A stay-synced code per reservation — Every booking gets its own code with a window built from the stay dates — active shortly before check-in, expired after checkout.
Codes guests do not have to memorize — Where the lock supports it, the code is the last four digits of the guest’s phone number, with a safe random fallback when needed.“Room 7 code: 4413, active from 3pm on your arrival day.”
Delivered with the arrival details — A template variable inserts each reservation’s code into scheduled messages and the guest guidebook, so instructions always match the door.

Automation

Guests can work the door from the guidebook — For deadbolts you enable, guests can lock and unlock straight from their digital guidebook during the stay — rate-limited, and only while the booking is active.
Codes follow the booking — Date changes move the code’s window; cancellations remove it. A rebooked room never keeps the old guest’s code.
Every door keeps its receipts — Unlocks, code changes and failures land in a per-device timeline — useful when you run many doors and need to know what happened at one.
Failures surface for action — Code-setting is confirmed by the lock; anything that fails — offline device, dead battery — is tracked and raised before it becomes an arrival-day problem.

How to connect 33 Lock

Connecting 33 Lock takes a few minutes and happens entirely in the browser:

1In ProhostAI, open Smart Devices and choose Connect account.
2Pick 33 Lock in the secure connection window and sign in with your 33 Lock account credentials.
3Your deadbolts sync in automatically with battery and connection status.
4Assign each deadbolt to its listing and name it for guests (Room 7, Main entrance).
5From the next reservation on, codes are created, delivered and expired automatically.

Good to know

33 Lock hardware is aimed at hospitality and multifamily doors — locks that expect constant guest turnover, with a metal key kept as physical backup.

ProhostAI manages only the per-reservation codes it creates; staff and owner codes stay on the lock untouched.

Multiple deadbolts per listing are supported — a building entrance plus a room door — each assigned with its own recognizable name, and the guest’s PIN matches across them.

Connected devices are a paid add-on billed per device, and ProhostAI never sees or stores your 33 Lock password.

Yes. Connect your 33 Lock account and ProhostAI creates a unique door code for every reservation, delivers it in your check-in messages and guidebook, and expires it after checkout.

They are built for hospitality — hotels, motels and rentals with constant turnover. Paired with ProhostAI, the per-stay code work that turnover creates is handled automatically.

Automatically. A template variable inserts each reservation’s code into your scheduled messages and the digital guidebook, so the guest reads the code alongside the rest of the arrival details.

Yes. Each code’s validity window is built from the reservation — it activates shortly before check-in and is removed after checkout, and the window follows if the stay’s dates change.

Yes. Guests can lock and unlock enabled deadbolts from their digital guidebook during the stay, and your AI employee can look up or regenerate the stay’s code on request — every action audited and rate-limited.
