The Key Fob widget included with Flow operates some interactive elements in airports and sceneries.
It works on channels — there is no limit to how many — and the scenery developer picks the channel for each interaction. Signs posted next to interactive elements always show the channel to use.

Add the widget
- Enter editor mode in Flow.
- Search for the “Key Fob” widget.
- Add it to an available tile on a wheel of your choice.

Operate the Key Fob
- Read the channel from the sign near the object.
- Scroll up or down in the widget to select that channel.
- Click the widget in the Flow wheel.
Transmission range is roughly 150 yards.

Developers who want to integrate the Key Fob can find the source code on our GitHub.
