H once had to use a drill in another house garage to open the house door when I was traveling…so there’s that.
We now have a key pad on the garage door and the door to the house is then locked. If we forget our key, one is hidden in the garage.
Once a freak snow storm happened when we were walking in shorts and a tshirt- it went from like 55 to 15 with a snow squall in 10 minutes and the electricity went out, therefore the garage door would not open. Our neighbor had a key and happened to be home. We solved that dilemma with carrying a house key on walks and hiding a key outside.
