如果你买了一辆备有新的无钥匙的开门系统的汽车,则你只要走近汽车,汽车门就会自动为你打开,十分方便。当你离开汽车时,钥匙链式发射器会自动发出信号,锁上安全系统,使它万无一失。如果钥匙插在点火孔内,车门就不会锁上。这就是装有新式自动车门的“康维蒂”轿车,它颇受人们的青睐。 If you buy a car with a new keyless door opener, you can easily open the car door as soon as you approach the car. When you leave your car, the key chain launcher automatically signals that the safety system has been locked to make it foolproof. If the key is inserted in the ignition hole, the door will not be locked. This is the “Comviti” sedan with a new automatic door, which is popular with people.
