Thanks. I was under the impression the app simply communicated to the car via the Internet using LTE or (hopefully in the near future for our 3s) WiFi.

Is the phone supposed to be tied to a driver profile? We thought so but it has never worked for us. We always need to change manually. And like most others it takes a few tries for the phone to work.
I heard that several months ago as well.... it’s supoosed to be. Maybe it’ll come in an update. But the car can handle multiple simultaneous connections, so how does it distinguish between driver and passenger if they both have profiles tied to their phones?

Yes I know...also it keeps the robbers from taking my credit card info. My wife got hacked in New York just using a bathroom. She does not have rfid. Why I got it.

I would have thought who approached First or if it can tell which phone is on drivers side. But either way it does not work.
The payment card industry has moved on to EMV chips. If your cards have the chip, you don't need to worry about RFID skimming anymore because chip cards don't use RFID. If you still do have an RFID card, demand that they send you a new one that uses the chip, or stop carrying that card around.
Regarding phone key being tied to a profile in the car, this functionality doesn't exist today, but I feel like it's very likely that it will be in the future. From an engineering perspective, it'd be really easy to do.

It was good that Tesla listened to the people who were having issues when their houses were very close to their car, but they should have made it a choice. I'd rather it unlock 10-15 away, because I don't have that issue.
That being said, about 90% of the time it unlocks when i pull the handle, and only 10% do I have to wait a few seconds.

It wouldn’t even be that much. The fobs for the S/X use RFID, just like the key card for the 3. Personally I MUCH prefer the key card and phone solution - it’s one less thing to carry since the card just fits in my wallet (like a credit/debit card).

Try turning Bluetooth off on your phone and then on again. I find this seems to prompt the car into pairing and then it will unlock.
Tesla switched to Bluetooth FOBs in 2016. At least for the X, not sure if the S ever made the switch. Tesla starts shipping new key fob with Bluetooth Low Energy (BLE)
It does for times when you are out of range of Bluetooth (i.e. you want to check your battery/charging status while you're shopping, or turn the heater on a couple minutes in advance on so your car is warm when you get in), but if that was the only means of communicating with the car, then you'd always have to have the card key with you in case you drive into a poor-LTE reception area. You pair it with Bluetooth when you set up the phone as key - it then uses that connectivity with your phone when it can. If it always used LTE, you wouldn't be able to auto-lock/unlock in a parking garage that was deep underground, for example, because there would be no signal for it to know where you are.
I've been trying to pay attention to how the phone key fails, and I'm starting to conclude that it's not due to the car sleeping, and at least for my phone, the problem is not phone-side. It's the car's BLE module. It must crash or get hung up at times and can't re-establish a connection with the phone, or the existing connection is stale and is waiting for some timeout before it tries a new connection. The solution is either to reboot the center console or to toggle BT/Airplane on the phone. That forces a fresh connection, and things start working again.
To me this feels like something that can be refined on the firmware side of things. I'm quite familiar with issues like this when I flash custom firmware on my Android phones. The bluetooth stack is notoriously difficult to get right for whatever reason. Hopefully Tesla will polish theirs up soon.

Exactly!!! The other problem is that my charger doesn't allow me to remove it until I open a door, this is real pain!! Anyone else hate this???
