Virtual Keyfob for Watch

This app will allow you to lock and unlock your Model 3,Y,S,X car without an active internet connection. The app acts as a key fob to the vehicle, allowing you to lock and unlock the car without an internet connection. This app will let you leave your phone or keycard home and drive your vehicle with only your Apple Watch.
This app is compatible with all Model 3/Y and 2021+ S/X.
The pairing process is similar to pairing the 'car key' feature in the official Tesla app. When you install the app on your watch, you will click 'Enroll Key' inside your car. A popup will ask you to tap your keycard to the center console, at which you should see an unknown key added to the locks setting screen on the car itself.
After you pair, you can use the controls in the app to lock, open the trunk, open the charge port, or open the frunk from the app.
Due to power saving in the WatchOS, the app must remain active (screen on) to stay connected to the car.
