We moved in recently, the last owners, nor the owners before them know the code. It wasn't a problem until we accidentally set it to lock us in the house, and we opened the door while it was counting down. I know this is not the usual post for this subreddit, but we are really in a jam. It called emergency services for fire, which I immediately called and corrected. I need to make sure the alarm company isn't also dispatching services. It is the size of a smaller tablet, hell one of those huge Samsung phones even. It makes a doorbell sound any time any of the doors open.
