Control Access Remotely with Latch Latch C1

The Latch C1 by Latch 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.
