TIL, if I lock my phone in the car on purpose (using the keycard), so, for example, my phone can keep charging, my car is still not really locked. If I wish to do that, turning off Bluetooth solves the 'problem' of the doors opening if anyone tries them.
I leave my phone in the car all the time by accident (black phone on black charging pad is not a visible reminder.) I solve that issue two ways:
1. Pin to drive so anyone getting in the car can't take it unless they know they can start the car via the app on my phone. If I leave my phone in the car by accident, in theory all that gets stolen in the phone.
2. Honk on walkaway lock. And while I apparently have been unable to train myself to take the phone when I leave, I have trained myself to listen and if I don't hear the honk, I check to make sure my phone is with me and lock the car with the app.
