Or just their keys! 
In nice weather we used leave the garage door open. I’ve never heard of people having their snow shovels, etc., stolen from garages in the neighborhood.
But now we have a cat who sometimes tries to escape, so we use the garage door as a catlock. (Like an airlock.) I’ve never worried, “did i close the garage door?” though.
This is the real problem.
I live in a low-crime area. Maybe once a year I have to pick up the contents of my glove boxes off the passenger seat and put them back in, in all of my cars, which I dutifully keep unlocked either on the street or in my driveway.
I do this because when I was 16, someone smashed my window looking for valuables. There were none, of course, so all I got out of the experience was a valuable lesson in the cost of a window replacement. I also drove a Miata up until recently, and everyone with a ragtop knows you don’t lock the doors unless you want to be ass-out for the cost of a replacement top.
This is a frequent topic of discussion on my neighborhood’s FB group, with lots of frustrated citizens insisting that our local police force “do something” about this problem because they’re tired of replacing their windows. The right wingers point out that they’re all armed to the teeth and if the cops don’t take care of the problem, someone is going to get shot. Not by them, of course, they’re too level-headed for that. But, you know, wink wink.
Meh. Keeping the doors unlocked and the car empty has kept my windows intact for 30 years.
Weirdly none of the thieves in this particular neighborhood rummage through garages. That’s been a problem in other places I lived, but I keep a lot of valuable tools in my garage and it’d be trivially easy to break into. That doesn’t seem to be a pattern, though. Maybe because that’d take it from a misdemeanor to a felony? I don’t know the laws about B&E.
Back when I owned an easily breakintoable older car, I considered parking it unlocked and making a sign to keep on the dash saying, “Nothing worth stealing inside.”
This for sure.
My wife and I where in the middle of moving one house to another. 100 miles away from each other. I got to my (now) old house and realized I had forgoten to close the garage door. Shit. There are thousands of dollars of tools in the new houses garage, and the door from the garage to the house is not locked.
I wasn’t going to the new house for days, I had to load up my car with shit to move.
We had just moved in, I did not have any neighboors phone numbers.
I did NOT want to just turn around and drive back 100 miles to close the door.
So, I called the small town that we live in. I think it’s called ‘Community Service Dept’. I explained my dilema. The woman on the phone said ‘Sure, I’ll close the garage door, what’s your address?’
She had to go into the garage, press the button and dash out as the door was closing.
She called 20 minutes later ‘Done’.
I think I’m gonna like this town. THAT’S Community Service.
That does sound like a nice place to live.
And - amazingly - done without some “smart” internet subscription! Amazing what meat puppets are capable of!
(Not to get you concerned or anything, but bonus points if you are able to locate the various surveillance trackers the community service officer planted while they had access…) 
Yeah. I was trying to figure out what to do. Call the Sheriffs office or local cops next. But the nice woman in town government said ‘Sure, no problem’.
I must say, I was impressed. But also must gloat. I worked in GIS for county Government for 33 years. We had access to all the data. Had to have it for our work.
Often things came across our desks that where a ‘What? OK. We can do it’.
Our attitude was that IF we can’t do it, by god we’ll find someone who can. This is often after people had already been transfered from deparment to deparment. Weird stuff always landed on GIS.
In my house, the door from the garage into the house is a steel exterior door that locks. I thought they were all like that. In a situation where a delivery person was given access to the garage, I’d definitely keep that door locked.
A million years ago when I was a dedicated regular back-country hiker, it was common at the trailhead parking lot for every other car to have a hand-lettered sign on the dash: “NO RADIO.”
I don’t get this. If I pull into the garage & go inside, I press the button on the wall & close the garage door as I step into the house. If I pull the car out to go somewhere (as opposed to just wash/fix something) I close the garage door before I pull out of the driveway. If I somehow brain-farted & didn’t close it at one of those two times there’s no reason later on to think I need to check on it because I already assume it’s closed
Do you have kids?
That’s how I feel. But I understand different people think/act/prefer to think/act differently.
So what do you do? Continually check:
Have the kids left the garage door open? Apparently not.
10 seconds later…
I’d say I leave one of the garage doors open once or twice a year. When I do, I get a text on my phone (and watch) at exactly 10:00 p.m. telling me that MyQ is closing the door. I think it’s a great feature.
I’d say another 3 or 4 times per year we have an occasion to open or close the doors when where not at home. (not for deliveries, that’s weird).
The other thing I love about MyQ is that we have our adult children get the App and give them access (full or limited) so they can come by when we’re not home and take out the garbage, let out our dog, or pick up something.
Speaking of smart garage door things, our Tesla X is programed to open the door when we are 50 feet away, and close it automatically when we leave.
What don’t you get? I’m very, very good at remembering things. But there are a few times when life puts so much in your lap that you do forget… something. Ever made a grocery list?
My house/garage isn’t configured that way. The garage is connected to the house but you can’t enter the house from the garage. I can walk past the front of the car through an exterior door where the button is or out through the big garage door. It’s easier to walk out the second way, especially if I’m unloading groceries or something. There’s a clicker on the foyer right when I enter the house but I forget sometimes especially when I’ve brought in a couple trips of groceries or just opened the garage to bring out or in the garbage cans. This is an issue particular to me.
Yeah, but I’m not sure the garage door is so unique (my personal opinion) that if I’m unsure whether I did something, that I need an app to clarify it. Only exception (for me) is if leaving on a trip. In which cases we make sure we sit there and watch the door close.
You can set it up to notify you if the door is open more than a set amount of time.
The point is that the door can open automatically when you drive up the driveway and close when you leave, based on your phone’s location (a geofence). No manual person-phone interaction necessary.
No, I ask because my garage is not just a car hold. It’s a tool shed, bike depot, toy bin, and mechanics bay. During the summer people are always going in and out for something. It mostly stays open during the day. As you suggest, the use case Spiderman suggests where the only reason the door opens is when a car passes through it is not everyone’s reality.
I don’t really care if someone left the door open so I don’t check my app ever but I suppose I could.
