Landlord scenario with mobile unlocks only

Use case example

As a tenant in a multi-office building, you may encounter a main entrance door that uses a legacy access control system. However, with Kisi, you can still ensure continuous access from the entrance door all the way to your own office door.

By wiring the existing legacy controller to the Kisi controller, you can utilize Kisi's mobile tap in-app unlocks to unlock the main entrance. This allows for a seamless transition between the two doors, providing a secure and efficient solution for accessing your office.


  • Minimum hardware changes
  • Maintain the landlord’s system’s functionality
  • Enable mobile in-app unlocks at the main entrance with Kisi

How it works

  1. The user taps to unlock in the Kisi mobile app
  2. The signal is sent to the Kisi controller
  3. From there, the signal is transmitted to the legacy controller through the Wiegand board's output channel
  4. The legacy system verifies and authorizes the credential
  5. The legacy controller unlocks the door
