Has anyone installed a digital key? Is this thing actually useful?

Doesn't the new car come with a digital key? My '25 model has it and it's free for the first year. I find it pretty useful—you can start the engine remotely, control the AC, and adjust the seat heating and ventilation. You can also lock and unlock the doors and windows. I'll use it for free the first year, and then decide next year.

Not very useful, not worth the annual fee.
