WTF??? involves a locksmith

Went to court with BFF and ignition key broke off in door- how was I suppost to know which key is which? I guess you cannot have camera phones in court and we needed to put ours back in the car. She handed me the keys and i ran back to car to put phones in. I only have one car key that opens door and starts car, she doesn't. Key broke in two pieces. Yikes- now what? Put phones on the wheel well of her car and prayed no one would see them and went back inside. After like 2 hours in court, we had to get a locksmith. $184 later she drove off.
