Phone key disconnected issues

Recently my phone key has been disconnecting, usually happens when I haven’t driven the car in few hrs or used any of the functions. My car wouldn’t unlock when I pull the handle or phone wouldn’t connect even when I’m close to it, but all the other features in the app works. I restarted my phone, logged in and out of app, re-paired my phone with the car, updated with latest software, but issue keeps coming back. Any advice on this? Thanks!

On Android at least, it helps to use the Settings app to turn off battery optimization for the Tesla app. That will allow the app to run in the background on the phone when the car needs to communicate with it.

Sometimes restarting the app (or the phone) helps.

The Bluetooth connection for the Phone Key is separate from the connection for audio streaming and phone calls, so re-pairing won't help.

Another thing you can try is the two-thumb reboot of the car's UI.
