If the code is missing or incorrect, the engine will shut down after one or 2 seconds.Component Protection: In newer A3 models, the key is part of a "part protection" community. This means the key is digitally married to the automobile's VIN (Vehicle Identification Number) and can not be quickly "single" to be used on another automobile.Approximated Costs of Replacement
