Seam Instant Key is the fastest way to share access—whether it’s a hotel guest, a real estate visitor, or an on-site contractor. With a single API call, you can create a mobile key and send it through text or email, or in your own app. There’s no app to install and no account to create. The user just taps a link and gets a lightweight, native-feeling experience using an iOS App Clip or an Instant App on Android. We’ve designed Instant Key to feel instant, intuitive, and secure. For issuing Bluetooth mobile keys, this is the most streamlined mobile access experience available today.
  • No app store visit required: The Instant Key opens instantly from a shared link.
  • Works offline: Uses Bluetooth, so even in areas with poor cellular or Wi-Fi, like elevator banks or concrete-walled hallways, the key still works.
  • Great for short-term or one-time access: Hotels, self-touring, vendors, or temporary staff.
  • Embeddable: Use the Instant Key link or launch the experience from within your own app.
Whether you’re phasing out plastic key cards or offering self-guided tours, Instant Key delivers secure access without the usual friction.
