KOS keys with panic alarm

I myself registered with the MUT3 4 KOS key with panic alarm.

The panic alarm button is actually only available in America and was never offered in Europe. However, it's a feature you might need someday.

I also have a Smart Key, which allows you to unlock the car simply by approaching it, and also via the app. But it's more of a nice-to-have feature.

I find the original KOS keys more attractive, more practical, and not so bulky.
