The main difference between car keys with and without chips is their functionality and security. 1. Functional difference: The main function of the car key belt chip is to identify and unlock the vehicle wirelessly. It is usually connected to the vehicle's wireless remote control and can remotely control the vehicle's opening and closing. The car key without the chip only has the function of physically opening and closing the vehicle, which needs to be inserted directly into the door or the ignition switch. 2. Security difference: The car key belt chip usually uses encryption and authentication technology to make the vehicle more secure. A unique identification code is stored inside the chip and can only be unlocked if it matches the vehicle's receiver. This prevents theft and copying of vehicle keys. Car keys without chips are relatively easy to copy and steal. 3. Convenience difference: the car key belt chip can realize remote unlock and remote control function, so that the driver can easily switch the vehicle. This is very convenient for users. The car key without a chip requires close contact with the vehicle or manual operation of the switch, which is relatively complicated.
In short, car keys with chips have more features, higher security and greater convenience than car keys without chips.
Simply put, there is a chip in the key that has been transmitting information to the outside, and the transmitting range is relatively small. When the person with the key walks to the car, the receiver in the car receives the key information (the information is encrypted and authenticated), and recognizes that the key is the key of the car and the key is already beside the car. At this time, as long as the door is opened, the receiver will control the automatic unlocking. In the same way, the key and the car have changed from the traditional physical contact pairing to the wireless signal pairing, eliminating the action of picking the key, but the key still needs to be carried on the body
