 Get another one. Or if you've got one key, just get another key for your car. They're just not that much. They'll save you. But I think in this case, what happens with these remotes, a lot of times you've got them in your pocket. You've got them anywhere where there's moisture exposed to them and the circuitry just starts breaking down and they do not transmit and receive as well as they used to. And they can get weak and just not start the car. But they seem to fail at the least opportune time. You'll go to get in it.
