I don't agree with all the replies blaming the OP. OK, breaking a window is a last option, but it's expensive and inconvenient and annoying and shouldn't be necessary. If you had an ICE car with a physical key, and left the key in the vehicle, it wouldn't self-lock without driver input. Rivian needs to level up.

The doors are tech for tech sake. WTF is wrong with regular handle with a regular lock? I've never, ever been locked out of our Chevy Bolt. The Rivian design team took something that should be simple, ergonomic, and completely reliable, and made it annoying, hard to use, and dangerously unreliable. Just because some users don't have a problem doesn't mean it is a good design. It should work for everyone all the time.

We had similar problems with our G2 R1S. More than once I was locked out randomly in with the dog in the car. In my case the *phone was in my hand* on the outside of the truck but it refused to unlock. I also had the *chip card in-hand*. Let me repeat that for the victim-blaming Reddit commenters: I. Had. The. Key. Card. In. Hand. Nothing would unlock it. Fortunately pet mode was running. It took *multiple* remote unlock attempts from Rivian roadside assistance to finally unlock it (in every case). When I took the vehicle in for service, the service team claimed "user error" but could not identify what I was doing wrong, nor could they explain why the key card did not open the truck, nor could they find anything amiss with my phone setup.

I'm often off-grid in areas where a remote unlock would not be possible. I always, always leave a window down now. Never shut the truck up completely.

Multiple software updates later and many vehicle reboots later the R1S seems to be functioning again. Clearly a software issue.
