<human>: I have a friend that is in a bit of a bind.  He lent his brand new car to his ex-girlfriend while she got "back on her feet".  That was a year ago.  She's still driving the car and he wants it back.  She gives him the run around all the time.  He keeps telling her to either take over the payments or give it back but she's not giving it back.

The car is completely in his name, I believe insurance as well.  The car has a loan which is in his name at his bank.  He does not have a set of keys for it.  He gave both keys to her.  It's literally as if he just handed his keys to someone and said "Here, drive this around as needed."

I keep telling him he needs to take the car back, because she apparently won't give it back.  The plan is to go to the dealership and get another set of keys made for the vehicle (he has all the paperwork).  Then simply go pick the car up, right out of her driveway (she parks it outside).

My concern, is there anything illegal about this?  If she still has something inside the car when he takes it, can she press charges for taking her stuff?  Can she press charges for simply taking his car back unannounced?  What if she claims she had a diamond ring in the car worth thousands when the car was taken? etc.

Can you condense the text into three sentences or less?
<bot>: My friend lent a car to his ex....she won't give it back.  Is it legal to simple go take it from her driveway?
