Having the front camera replaced in my 580 SUV due to a crack in the front camera from a road rock. It is at the dealership. Sometime early today I received notification the doors were unlocked and out of habit, and not thinking things over, used the phone App to lock the doors. Dealership phoned this afternoon and said the new camera had arrived but they couldn’t get into 580 as the doors were locked with the keys inside. It was fun unlocking the doors for them some 30 miles away….😊

 

Makes sense if you accidentally leave the fob in the car, you should be able to lock it remotely from the app.

 

Most likely have to the key being inactive due to the sleep function in the car and the car thinks the key isn't there and therefore allowed the locking to occur, especially if the ignition wasn't on.
