How to Replace the Only Car Key If Lost?

[McCollin]

Every car comes with an anti-theft code configured with the vehicle. As long as the owner provides the vehicle license and identity information to the 4S store, the 4S store can obtain the vehicle's anti-theft code based on the provided information and configure a new key. The following is a partial introduction about car keys: 1. Classification: Car keys are divided into two types, one without an anti-theft chip and the other with an anti-theft chip. Keys with anti-theft chips are commonly found in some low-end models, which don't even have a remote control and are rarely seen nowadays. 2. Smart key: A smart key is equivalent to a small radio wave transmitter. The chip inside the key contains a unique ID code that matches the owner's car. When the smart key emits a radio wave, which is received by the car, the car's anti-theft system control unit confirms the key's authenticity, allowing the door to be unlocked and the engine to be started.
