Automate Access with TTLock Entr

Check requirements: Requires connectivity setup

A core use case is syncing access codes with reservations from your booking system. With Seam, you can plug calendar tools like Calendly, Cal.com, Google Calendar, and iCal; e-commerce backends like WooCommerce or Shopify; or even class- or appointment-booking software like Mindbody and Acuity. Every confirmed reservation can be set to automatically create a unique, time-bound code on the Entr at check-in and revoke it at check-out—no manual handling, no shared codes.

The Entr by TTLock can be used to automate secure access for your customers, guests, or users using Seam's self-serve solution.

With support for time-based access codes, you can automatically grant and revoke access based on real-world events like bookings, schedules, or user actions—without manual intervention.

This is especially useful for:

Using Seam, you can connect your Entr, listen to events from your booking system or backend, and programmatically create access codes that are valid only during the desired time window.

Control Access Remotely with TTLock Entr

Check requirements: Requires connectivity setup

The Entr by TTLock supports remote unlocking via the Seam API.

Beyond admin or staff workflows, you can embed an "Unlock" button directly inside your customer-facing app, allowing authorized end-users to open a door, gate, or locker themselves during their reservation or membership window—no front-desk hand-off required.

This pattern works particularly well for:

You can also trigger unlock actions programmatically—for example:

  • Add a button in your app or admin dashboard to unlock a door or gate
  • Allow staff to remotely grant access during a reservation
  • Enable backup access in case a user cannot use their code
  • Build simple interfaces for operators to manage access live

Combined with scheduling or reservation logic, this allows you to create flexible access experiences—for example, enabling a "Unlock" button that only works during an active booking time window.
