Every reservation becomes a guest access code
When a booking lands on your calendar, Seam generates a guest code on the right lock, activates it at check-in, and removes it at checkout. You don't lift a finger — and your guests never wait on a key handoff.
Reservation lands
Booking comes in from Airbnb, Vrbo, Booking.com, your PMS — anywhere with an iCal feed or supported integration.
Code is set on the lock
Seam picks the right lock for the property and programs a unique code timed to check-in and checkout.
Code expires automatically
When the guest checks out, the code is removed from the lock. No lingering access, no manual cleanup.
Every lock, every battery, every code — in one grid
See lock state, battery level, and active access codes across every property at once. Drop into any device for full activity history and current credentials.
Lock and unlock from the dashboard
Battery and connectivity badges on every card
Live access-code count per device
Filter by property, status, or attention needed
Works with the tools you already use
Paste an iCal URL or connect a supported PMS — Seam picks up reservations and keeps them in sync. Map devices to properties once; the automations follow your bookings from there.
Bring your booking platform
Airbnb, Vrbo, Booking.com — anything with an iCal URL works out of the box. Direct PMS connections for Guesty, Hostaway, Lodgify, Hospitable, and more.
Map devices to properties
Group locks, thermostats, and sensors under each rental. The assistant suggests mappings based on names and connection accounts.
One code per stay, automatically
Codes activate at check-in, expire at checkout, and never overlap between guests — even on back-to-back bookings.
Compatible with 100+ smart lock brands
Bring the locks you already have, or pick from any of the brands Seam supports. New brands are added every month.
Ready to put your rentals on autopilot?
Spin up a workspace in minutes — no credit card, no API setup. Bring your first property and lock; the assistant takes it from there.
—“Discovering Seam was one of these Aha moments in the business. I couldn’t believe what I was seeing. I mean, it was exactly what we were looking for: a simple API that we could integrate and have access to all these devices in a matter of seconds.”
