Yale

Ask hosts which keypad sits on their rental doors and Yale comes up early — the Assure line was designed around exactly this: a clean keypad on the outside, no key to hide under a mat. But the lock has no idea a Friday check-in exists. Someone still has to decide the code, program it, send it, and clear it out again on Sunday.

Hand that job to ProhostAI. Connect the account you already use in the Yale Access or Yale Home app, assign each lock to a listing, and from the next reservation on every booking carries its own code with a validity window built from the stay dates. Where the lock supports it, the code is the last four digits of the guest’s phone number — a number they already know — with a safe random fallback otherwise.

The code travels on its own: a template variable places it into your scheduled check-in messages and the digital guidebook, so the digits the guest reads always match the digits on the keypad. And the code exists early: it’s minted the moment the booking is confirmed, its window opens 12 hours before check-in by default, and it closes at checkout exactly.

On the hardware side, some Yale models pair with a Yale Connect WiFi Bridge for remote access. If a lock is reachable remotely from your Yale account, ProhostAI can manage it.

With your Yale account connected and each lock assigned to a listing, the routine runs itself:

Guest access

• One code per booking, windowed to the stay Every reservation gets its own entry code that activates shortly before check-in and stops working after checkout — nothing to program, nothing to remember to delete.
• Phone-digit codes guests don’t forget Where supported, the code is the last four digits of the guest’s phone number, with a random fallback when those digits aren’t available or are already on the lock.
• Sent inside the messages you already schedule A template variable drops each stay’s code into your check-in messages and the guest guidebook, so access instructions never go out with stale digits. "The keypad code for your stay is 7302 — active from 3pm Friday."

Automation

• Guests can work the door from the guidebook If you enable it, guests can lock and unlock the door straight from their digital guidebook during the stay — no app to install, and every action is rate-limited.
• Date changes carry the code with them Extended stay, shifted dates, cancellation — the code’s window moves or the code is removed to match, so last month’s guests can’t open next month’s door.
• Set-and-confirm, with failures surfaced Code changes are driven through to confirmation from the lock. If a Yale lock is offline or its battery dies, the failure is tracked and raised instead of silently dropped.
• A timeline per lock Unlocks, code changes and failures collect in a per-device history, so questions like “when did the cleaner arrive?” have an answer.

Connecting Yale takes a few minutes, entirely in the browser:

1. In ProhostAI, open Smart Devices and choose Connect account.
2. Pick Yale in the secure connection window and sign in with the account you use in the Yale Access or Yale Home app.
3. Your Yale locks sync in as devices, each showing battery and connection status.
4. Assign every lock to its listing with a name guests would recognize — a building entrance and a unit door can both belong to one listing.
5. From the next reservation on, codes are created, delivered and removed on schedule.

• ProhostAI manages Yale locks that have remote access through your Yale account — some models get there with a Yale Connect WiFi Bridge, so check the lock is reachable in the Yale app first.
• Codes you programmed yourself — owner, cleaner, maintenance — are never touched. ProhostAI only manages the per-reservation codes it created.
• Connected devices are a paid add-on billed per device, so a single Assure on one listing costs the same to run as any lock in a larger rollout.
• The connection is a secure, OAuth-style sign-in — ProhostAI never sees or stores your Yale password.
