When I first got mine, we went to Canino's on Airline.
We milled around in and out, it was an extremely hot day.
We paid and made our way to the car. I unlocked it by pushing the button, dh put our purchases in back. As I opened the door I said omg wtf, it's running and freezing cold.
The key was in my pocket, we moved to a better parking spot and there were a few of us caught up talking.
I now make a point to check sunroof and windows, lights and I'm mindful about shutting it off.
I have dropped dh off at the store to run and grab with him having the key in his pocket. It is displayed on the dash, no key. If I had gone to the pumps while he was in the store I would have to wait for him. You have to have the key in the car for it to start. He can't be loading the back and me start the car.
We like it, however we have changed the batteries in the fobs once. While changing the one we carry, we change the spares too. We have never used them but if needed, they need to work.
We've never tried to use the key manually. I don't think mine has e er been out of the fob. 4951
