I got app Tesla remote $30. Use on my watch. Hey Siri unlock, start climate, open trunk, etc. on shortcuts. Took awhile to get working properly(delete short cut app and reinstall) but fine now. Very convenient.I see a bunch in the app store, and have been sifting through them. But before I buy one (or two) I thought I'd see if anyone has a favorite.
I'm mainly looking to use my watch as a key, and to open the trunk and frunk. Things that would be helpful to be able to do when outside the car and perhaps you left your phone in the house, a bag, etc. Or in case you locked your phone in the car. Ugh.
