Have you tried holding the phone right next to the spot where you put the card key? I have a 4a 5G and at times I have to hold it close to that spot to get recognized. Same with the door pillar spot when unlocking. May happen more when my phone battery is low.I just realized I too have been leaving my car unlocked. I am now trying to reconnect the phone key after removing and reinstalling app and it fails to connect. Bluetooth will connect, but the car, key card and phone will not communicate. Who do I escalate this to? Google? (Have a Pixel 4a (5G).
