Hardware 3.0 Upgrade and Phone as Key Issues

I have 2018 LR RWD (June 2018 Build) that I just got upgraded to the 3.0 hardware computer about two weeks. Ever since then I've been having all sorts of issues with using my phone as a key - currently using an iPhone 11 Pro Max. So I am unable to automatically open my car or drive it. As far as using this phone with the 2.5 hardware, I never had any issues. It seems like every other day, I get a message in the Tesla app stating to connect my phone as key. Sometimes I have to reconnect my phone 2-3 times in a day. The app does not log me out and and I am able to perform all other functionality within the app (vent windows, honk, unlock doors, etc..) but for whatever reason, it keeps kicking my phone out as the key. I checked the vehicle itself and it has my phone listed on the list along with my two other key cards. Every time I've reconnected my phone as a key, it is listed again on they key list in the vehicle. I have deleted my phone from the list in the car's settings, I've deleted the Tesla app and downloaded it again only for it to keep happening. I'm on the latest version of iOS and the latest version of the Tesla app. I'm currently on software build 2020.24.6.1. Has anyone else had this issue?

TL/DR: Ever since upgrading to hardware 3.0, app keeps telling me to connect phone as key. Makes me do it every other day even though I've connected it multiple times. Updated all apps and software. Can't fix :(

They sometimes end up resetting the profiles during the upgrade. It doesn't seem like that's the case for you, but maybe it was improperly migrated.

A thing you can try which might not work at all (probably won't, but maybe):
  • Delete your phone from the vehicle
  • Clear the data from the Tesla app (I don't remember how to do this on iOS, sorry, but it's in Settings somewhere, not in the Tesla app)
  • Create a new driver profile (you will need to redo all your settings, including Sentry/Summon/etc.)
  • Delete your old driver profile
  • Pair your phone again
As a side note, people have been having Bluetooth issues in general with a recent update. It could easily be related to that and not the hardware swap.

Possibly one other thing to try before wiping all data and profiles, is just change the password on your Tesla accout, and then log out and back in on the phone/car/etc. It seems changing the password has some effect in terms of resting things for some types of issues.

Also have recently upgraded to HW3 in a 2018 LR RWD (end of April). Had to re-pair the phone with the car after the upgrade. I use a Samsung Galaxy S6 Edge as key. Performance with HW2.5 and HW3 seems to be about the same; namely, about a 99% success rate at unlocking the car as I walk up. There have been a couple of times the car did not unlock after the HW3 upgrade so I used my fob to open, but the same thing happened with the older hardware as well. I believe that walkaway lock has been 100% reliable; there were a few times where I didn't hear the confirmation beep because of ambient noise so I pressed the fob just to be sure.

I experienced this today for the first time. Try going into your phone settings and turning airplane mode on and then off again. That was what the app suggested. It worked for now, will see if that holds up over a few days.

BTW, never had that happen on HW 2.5 Car was upgraded to HW 3 end of April and this was the first time it happened tome.

I think it's a good idea to change your Tesla password just in case your old hardware was not destroyed properly and ended up on eBay. I also changed my home WiFi SSID and passwords as well.

Changing the wifi, fine, that’s a good idea if you want to take care of the compromised MCU issue. But: The car has no idea what your Tesla logon is. Your phone uses it to talk to Tesla’s servers, not to the car and it’s not stored in the car.

The car talks to Tesla’s servers with its own security keys and has nothing to do with with your login or password. Just FYI.

I don’t want people to know my wifi SSID and password and address to my house and drive up and send death threats to the President or download child porn or try to hack the systems on my home network. That has nothing to do with Tesla info and why I stated the WiFi comment on its own.

Yes the chance is practically 0 percent but why risk it. The effort to change these things is minimal and costs nothing.
