汽车钥匙，指的是开关汽车的工具。现在汽车钥匙均使用芯片，为磁性芯片系统。汽车点火锁芯的读识线圈将对钥匙的芯片进行读取；芯片都有固定的数字信息。
Car key refers to the tool for opening and closing the car. Now the car keys all use the chip, for the magnetic chip system. The reading coil of the ignition lock cylinder will read the chip of the key; the chip has fixed digital information.
遥控钥匙，是指不用把钥匙键插入锁孔中就可以远距离开门和锁门，其最大优点是：不管白天黑夜，无需探明锁孔，可以远距离、方便地进行开锁和闭锁。 从车主身边发出微弱的电波，由汽车天线接收该电波信号，经电子控制器ECU识别信号代码，再由该系统的执行器（电动机或电磁经理圈）执行启/闭锁的动作。该系统主要由发射机和接收机两部分组成。
Remote control key means that you can leave the door and lock the door at a long distance without inserting the key key into the lock hole. Its biggest advantage is that it can unlock and lock the door at a long distance and conveniently, no matter day or night, without exploring the lock hole. A weak electric wave is sent out from the owner's side, and the electric wave signal is received by the car antenna. The signal code is identified by the electronic controller ECU, and then the actuator (motor or electromagnetic manager circle) of the system performs the opening / locking action. The system consists of transmitter and receiver.
