That is what mine does, but since it stays unlocked it is only the has the noise, not the lock cycle. First time it caught me by surprise, especially since I was working on the other car. It was a what did I just do moment. I know the WiFi connection and the auto updates are off so it is not related to any updates and my phone is the only one with the app which is/was on the work bench. It may be related to one of the key fobs being nearby. I don't really worry about it anymore.
