How do you legally scrap an abandoned car?

Follow up question. What's the best way to get it onto a trailer? Basically I'll have to knock the window out to get inside, once I get permission from the manager. Can you shift a car from park to neutral/drive without turning it on since I won't have a key to start it with? (my lack of interest in automotive mechanics is really coming back to bite me haha)

After all the legal stuff, then you might have to pop the ignition lock to free up the steering wheel and take it out of park for easy rolling. A winch or come-along will put it on the trailer/ or tow dolly.
