Car won’t unlock unless app is open?

I have had the same issue intermittently and was told by Apple that apps even running in the background are eventually killed (ie turned off) to save on battery and computing power.

I have had the same issue on an intermittent basis on Model Y using my iPhone. I was told by Apple that even apps running in the background are eventually killed to save on battery and compute power.

Android has a way to keep them from being killed. Are you certain iOS doesn't also?

I would never rely solely on the phone as a key - it's very convenient, but, at least with iPhones, sometimes weird stuff happens and the phone needs a full shut down and restart, or the latest update changed some of the setting you didn't know were reset, etc. So, just know you have an RFID way to enter and start you car, whether you use the card, a key fob, or a ring.

Sometimes I forget to launch the app on my iPhoneSE before getting to my car. Occasionally I can get in, but it won't let me drive and I need to launch the app. I don't think I've had a problem when the app was still running in the background.

It was nearly the opposite when I had my old iPhone 6. I almost never had to launch the app and could get in and drive away.

How do you keep apps running in the background on iPhone?

My wife had the same problem with her Iphone. It never resolved and has always been hit and miss.

I'm an android purist, and have rarely if ever had problems with my phone.

My 3 definitely unlocks/locks WITHOUT the App running. I'm wondering if it has something to do with "background app refresh" running on IOS?

Simple question I can't find an answer to: Does my cell phone need to be powered on to open my car doors?

The cell phone needs to be on, not powered off.
You must be “logged-in” the app.
You must have Bluetooth on the cell phone so that the car can sense your presence.

Not if you want to open your door with a card key or fob. If you want to use the app, your phone must be on (with Bluetooth connection on), but not necessarily awake.
