Still unsure of problem. Upon return from work the door was wide open, I texted owners about the issue, and they asked about the possibility of the battery for doorknob keyless entry being dead. Which did not explain why the bag of mulch was spread out in the front garden area. Also the temperature is Bluetooth controlled so if you want to come back to a nice cool place after a hot walk to the townhouse don’t bank on it, the heat was turned up to 75 while we were gone which also brings the question of how did the owners know we were not there when my car was still present.
