When I have my dog with me I will leave any car I am in running with the air on. Tried that this weekend with the Niro and it will not lock when running. Where I live that will work, never lock the car anyway so I am not worried about it running with it unlocked even when at Walmart. But this weekend I was in the city so the girlfriend had to wait in the car with it running. It is a big problem for me. Any way around this?
