vin with ownership proof
write the vin down and take it to the dealership WITH PROOF OF OWNERSHIP, ie...insurance card/bill/papers, title, plate registration, ANYTHING THAT SHOWS DEFINITE PROOF that it belongs to you. They can cut ya' one on the spot, but may be some $$$
MOST IMPORTANT BRING PROOF OF DEFINITE OWNERSHIP...hell even get a police report that your locked out of your car in YOUR driveway without the key
