SO....I did what I'm about to share and my Pixel 8 Pro which used to be fairly unreliable, became reliable to where I only have used my key fob ONCE in all of last month and that too as added insurance as I knew it may rain. Its made the whole thing way more predictable in that I know that at a certain radius away from teh car, the door is about to unlock.
Anyway...here's what I did...I went to an open space (I think it was a parking space for a large public park) and I redid my Bluetooth carkey and audio connections from my phone slowly and diligently. Since then, I've had zero issues. And now I agree with all the tech folks who are going to tell me that doing it in my garage vs an open space shouldn't matter...and I agree as someone with a EE in Digital Signal Processing that what I am suggesting absolutely should not matter...but it somehow did. My sense/logic was that I simply wanted to pair my phone and car in as less 'noisy' an environment as possible...in tech jargon, I was looking for as low a 'noise floor' as possible so that the Signal-to-Noise-Ratio (SNR) for my devices' Tx/Rx was as less immune to noise spikes as possible...and again...YES I agree that it shouldn't matter...but since I did the setup in a very low EMF noise environment...and I've really had drastically better results. If someone could try this and see if they can replicate this I'd be grateful! Thanks!
