Confession: I have never once unlocked a door to our house with a key, and entered that way. 

Every single time I've come home, I've entered through the garage.  My car has a built in button to open the door from inside the car.  And if that were ever to fail, I have the actual garage door opener in my glove box.  This week my car happens to be getting some minor work done, so I've been driving a rental, and using that spare garage door opener. Tom does the same thing.
