The Bluetooth key on Apple Watch

Apple Watch can have its own Bluetooth key, separate from the iPhone’s. With it, the watch commands the car over Bluetooth when you’re next to it, even without a network.

Adding it

1. Sit in the car, with your key card.
2. On the watch, tap … at the top right, then Bluetooth Key.
3. Tap Set up, then Start.
4. Place your key card on the center console, then confirm the new key on the car’s screen.
5. Once the key is active, tap Test the key: the car flashes its lights.

If the watch shows “Bluetooth is off” or “Copeel has no Bluetooth access”, turn it on or allow it in the watch’s Settings.

Removing it

On the same page, tap Remove key, then Remove. If the car couldn’t drop it, the watch shows “Key still in the car”: remove it from the car, under Controls › Locks.

Each key, the watch’s as well as the iPhone’s, counts toward the 19 keys a car takes at most.
