Less of a worry if it’s in your garage. I’d worry if it was in a driveway though. It’s very possible. You’ll be able to see clearly on the app. It doesn’t tell you that you’re still connected though unless you physically check the app. I’m not complaining, the range is a good thing compared to my BMW with a key fob but as someone who uses the phone for a key the range can be almost too good. I was at a bar the other night and my car was parked out front and was still connected. In that case I just check and turn off the Bluetooth on my phone
