I think I know what he is talking about. If you are installing a DEI product and you don't have a bit writer then you have to use a transponder which has a copy of the key in it. If the installer did not take the time to properly hide the transponder and alarm brain then all some one has to do is crack open the transponder and take the spare key and drive away with the car.
