Did the key from your 2003 fit into the cylinder easily, but you applied a lot of torque trying to get it to turn, or was it difficult to get the key inserted into the cylinder? You may have bent/broken tumblers or wedged the casting of the cylinder.

I'm not aware of a way to fix this without removing the key cylinder and inspecting it.

Are you able to get into the car either through a lock on the passenger door or by climbing through the trunk so that you can get the driver's door unlocked and open?
