How does the repo man get a key to your car?

I am a repo-Woman. If you purchased your car from a car lot, the car lot keeps a copy to the keys in case they need to reposess the car in the future when you dont pay. The repo-person can also get a key to the car from a dealer, such as GMC, etc. Or they can have a blank key, that accesses any car. If they dont have a key, they can tow it without a key. Pay for your car and you dont have to worry about it, :O)
