The keys do not have to be in the ignition and the car does not have to be running in order for you to be convicted of a DUI. Whether you can be deemed as in "actual physical control" of the vehicle, as the law requires, depends on all of the relevant facts, but from what you've stated in your question, it appears that you could be convicted of a DUI. You can still always choose to take the charge to trial, but it does not sound like your public defender's suggestion is completely off base, as you'd have to prove a lot more than just the fact that the keys were not in the ignition or visible.
