That will be a problem. I believe that without one of the original master keys the transponder key ECU has to be replaced with a new one in order to register a new key with no existing keys.

Do you mean I have to replace a new ECU? How much will it cost?Could I buy a transponder key from ebay and let the dealship cut and program it?
