You can leave it unlocked, but take the key out of the car. If the key stays in the car may not go completely off as it will read the key.

I think the battery test was not accurate so I would ignore that and have a proper mechanic test it. It does sound like that's the issue.

I Love LA. It lets me ride in the winter with the top down.
