Re: IoT - where the S really is for Security
I suppose you could have it on the inside; as you said, if you're on the outside and the lock installs a bad update, you're out of luck. If the lock is anything like the August one I used to use (don't shoot!), it updates via a user command on the app, not over WiFi and not automatically. In this scenario, the app could tell you to make sure you're inside before initiating the install. Just a thought; I don't design smart locks so you're safe for the time being.
