Taught a lesson by remote start..

So, I went to pick up by spawn at school on Thursday of this week. BTW, I'm in the San Antonio area, and a cold snap has hit here. Turned off my ct, and left the key behind on accident. Waited and waited in what felt like a freezer for about 10 mins. Remote started the car via the mysubaru app, and I was successful. However, it did lock all the doors in the process. Luckily, I was able to unlock it via the app. I'm gonna assume (I know) that it's probably to prevent it from being stolen or maybe for safety. Just wanted to let people know what would (most likely) happen.
