Just got the passive entry fob. Paired it to the car and then turned off Bluetooth on my phone.
Then I went to the post office. It worked on the way there but then I went to put the package I got in the trunk and the trunk wouldn't open. Tried to open one of the doors and it wouldn't open neither rear nor front. Had to double tap the middle button to unlock the doors. Then subsequently locked the car and tried a door handle and it eventually worked.
Drove home and parked. Walked away and car locked itself. Got home and realized I forgot the package in the trunk. Same thing happened trunk wouldn't open rear door wouldn't open. Eventually holding the fob in my hand long enough the door did open and I was able to open the trunk.
Tldr; seems passive entry fob is not any more reliable than my phone. Based on my very limited experience so far, actually less reliable than my phone.
I'm carrying the fob in the rubber carrier from the Tesla store in the front right coin pocket of my pants.
