That’s exactly what it is. My old neighborhood had a rash of vehicles ransacked and items stolen. The individual(s) would go house to house in the middle of the night and check the doors of vehicles parked in the driveways. They’d take whatever they could stick in their bag(s) and go on to the next vehicle. As they never damaged vehicles to take items...the sheriffs department would take a report, but I’m guessing it went right in the trash.
I followed-up on a report and never got a callback. My old Land Cruiser had a very sketchy keyless entry fob. It worked maybe half the time on the first press. I’m guessing that I pressed the button that one night, was in a hurry, and didn’t confirm that it was actually locked.
