I don't know what dealer you spoke to but the only way to reset a two button plip (fob) is to plug the car into a diagnostic computer.
To get the car to the dealers, you should have a security code with your handbook. You can use this code in the door lock to get you going. If you don't have the code a dealer can supply it with proof of ownership and proof of ID.
