The lorry's computer system confirms the key's distinct hash code.Teaching the Key: In older models, the key may need to remain in the ignition for up to an hour while the car "finds out" the new transponder code.Keyless-Go Setup: For cars with push-button start, a different programs action is frequently required to ensure the proximity sensors recognize the key when the driver approaches the automobile.Maintenance and Care for Mercedes-Benz Keys
