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 lock/unlock your car as you walk towards/away from it (You will need to occasionally manually open the app as WearOS will stop the app to save power)
* Summon forward and reverse (Enable in settings - your Tesla must have EAP or FSD)
* Automatically unlatch the driver's door when close to your Tesla (Enable in settings)
* Unlatch driver and passenger doors
* Manually lock/unlock
* Open the frunk
* Open and close the trunk
* Open, close and unlock the charge port

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

To install you can open Google Play Store app on your Wear OS watch and search: "Watt Key" or open Google Play Store in your web browser and search "Watt Key". For some reason the Google Play Store phone app will show the app as incompatible with your devices. You MUST have Bluetooth and Location enabled or Watt Key won't be able to find your Tesla.

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.

This app runs in the foreground as a service so that it can auto connect to the car as you get close to it. This avoids you having to always wait for the app to connect on every open and command you send. You must leave this service running and not block the notification or the app will cease to work. This foreground service will occasionally be closed by WearOS to save power and you will need to open the app to get it running again.

If you have any issues while using the app please email me so I can help: joshendy89@gmail.com

Works best on Samsung Galaxy Watch 4 and 5, 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.
