No if the transponder don't work you couldn't synchronize the remote with the car. If you are able to synchronize the first key (what starts the car) pusch the open button 5 times and within 5 sec put the key in the ignition switch and go to pos2 there are a few shops who can make you a third key of a fully funktional key.
