yeah, a coat hanger, but its horrable on the weatherstripping. I would think a dealer would be able to make a key providing you get the VIN, and you actually own the car.
Just call a towing co. They have the tool to get in it. I've been able to get in them using a slimjim, but it isn't the right tool for it, and it's difficult.
Or you can bust out a window. (not reccomended) The coathanger would be the first thing you want to try. If you still cant get in, call a local locksmith. (prolly cheaper than getting a key made at the dealer)
