Just got my car last week. Today I realized I could open the car with the keys in my pocket and just by grabbing the door. I have apparently also discovered a way to open the gas tank door without pressing the button. I've done it 3 times now and I have no idea how. Is there a way to do it by grabbing the door handle or something? The button is out of the way and I'm pretty sure I haven't accidentally hit it 3 separate times today without ever doing it before.
