No.

 

Which means (pure speculation) that, like most similar tech, the phone app uses a server somewhere and there is no guarantee that somehow the vendor can't lock you out of, or, otherwise control your vehicle. No thanks.

 

Many functions of the Tesla app including tire pressure, opening the frunk/trunk/doors, locking/unlocking, lowering/raising windows, operating the climate control/heated steering wheel/heated seats, turning on/off Sentry Mode (video recording), honking the horn, flashing the lights, opening/closing the charging port door, adjusting the volume, displaying the odometer/VIN/software version, download/install software updates, activating Bioweapon Defense Mode, or remotely "starting" the vehicle so someone near the vehicle who doesn't have a key can drive it all go through a server. You can also see where the vehicle is at all times, how fast it is traveling, what is playing on audio system, how much range is left, and which door(s) are open - this is one reason Teslas have such a low theft rate. And, there is no extra charge for this capability.

However, using a smartphone to unlock the vehicle is done locally without going through a server.

 

Here is a great thread about installing a Firstech Drone system to do what you want. I plan to install this in my 2022 when I can get to it.

I wonder if @securityguy left the Firstech Drone system in his RL when he sold it?

 

I'm not buying anything that requires a subscription if I can possibly avoid it.

 

 

'FOB' is not an acronym (in the context of keys).

It's just 'fob'.

 

fob is a noun:

Definition of FOB

watch pocket; a short strap, ribbon, or chain attached especially to a pocket watch; an ornament attached to a fob chain… See the full definition

Correct. Meaning it is not ALL CAPS.

'FOB' implies acronym or abbreviation. 'fob' is a noun.

 

Does the local unlock use Bluetooth?

Yes - the vehicle shows up as a Bluetooth phone key.

Does the connectivity for other functions use cellular?

That appears to be the case since there have been a few instances where I could not communicate with the vehicle due to no cellular data connectivity in the vehicle (AT&T) or my phone (Verizon) even while within Bluetooth range.
