Iphone 12 won't unlock my Model 3 but does auto lock on walk away.

I have just been delivered a model 3 and have phone key installed. I am able to control the car from the app (lock and unlock, climate, driving etc) and automatic lock when I walk away from the vehicle works. The car doesn't however unlock when I walk up to it. I have to manually unlock it from my phone every time. Does anyone know why this issue is occurring? I have an iPhone 12 and Model 3 with the latest updates.

I have tried deleting the key, reinstalling the app and bluetooth and location is 'always on' and the app is running in the background (not force closed).

I have a 2019 M3 with v10.2 (2021.32.21) and a new iPhone 12 with 14.4.1. This is my wife's commuter car, and (tragically) I only drive it 5% of the time. Since I got the new phone a month ago, I was able to unlock the car with the app, but not drive it. The car recognized the phone because the app and my settings migrated from the old phone via iCloud, but that was it. I had the car "forget" the Bluetooth settings of that phone and that did nothing, and then I reset the Bluetooth connection (twice) but that did nothing. I did the steering-wheel-two-button screen reset, and I shut down and rebooted my phone, and that did nothing. Came here for more answers.
Ten minutes later I went out and the phone key was working, without me having done anything new. I could get in the car and drive it, and when I walked away it would lock itself, but it wouldn't enact my driver profile and I had to tap my name on the screen so I could override my wife's shrimpy-little-leg setting so I would fit behind the wheel. So I'm 90% of the way there, but would love to have the driver profile recognized.
On another thread (Auto phone key not working) I saw the comment:

"Delete the phone as key from your car and set it up again. Note, its not the same bluetooth setup as pairing for music."

How do I do that? I don't want to delete all my drivers settings- seat/mirrors, etc... TIA!
