Watt Key — Watch App for Tesla Android

Watt Key — Watch App for Tesla

Turn your watch into a key fob for your Tesla

Features & Capabilities

Turn your Wear OS watch into a key fob for your Tesla. This app connects to your Tesla(s) via Bluetooth and allows you to:

* Automatically unlock/lock as you walk towards/away from your Tesla
* Automatically unlatch the driver's door as you approach
* Unlatch any door (or all of them!)
* Manually lock/unlock
* Open the frunk
* Open and close the trunk
* Open, close and unlock the charge port
* Tile for quick access to commands

Only works on Tesla's with Bluetooth key functionality: Model 3/Y and the new refresh Model S/X.

You MUST have Bluetooth and Location enabled or Watt Key won't be able to find your Tesla. The Watt Key notification must be allowed or the app won't be able to run in the foreground.

No internet connection is required, just your Wear OS watch with Bluetooth turned on. As the app connects directly to the car, actions are immediate and there's no noticeable delay between pressing the buttons and the car performing the action.

Works best on Samsung Galaxy Watch 6 and higher, and the Google Pixel watch.

This app requires your watch to have Wear OS version 2 or higher. Unfortunately older versions of Galaxy Watch have Tizen OS and not Wear OS so you'll be unable to use this app on those watches.

Security and privacy:
This app generates a secure cryptographic key that it uses to authenticate with your vehicle. This key is stored encrypted on your watch and can only be accessed by the app. At any time you can delete the key or all keys from this app via the Settings menu and also delete them from within the Lock menu on your Tesla. Watt Key supports Tesla's new end-to-end encrypted commands.

Disclaimer:
This app is not endorsed by Tesla. Use at your own risk. No guarantees are given as to functionality or uptime as this is very dependent on Tesla. You are responsible for any changes you make to your vehicle using this app.
