What to Do If Your Car Key Is Stolen?

[EmilianoMarie]

Immediately go to the 4S store to replace the entire set of lock cylinders. Since it's uncertain whether the key was lost or stolen, and if someone knows your car, it could be troublesome, so it's best to replace them all. When replacing the lock cylinders, the identification codes will be rematched, making it even more secure. Below is an introduction to remote keys: 1. Advantages of remote keys: A remote key allows you to unlock and lock the door from a distance without inserting the key into the lock hole. Its greatest advantage is that, regardless of day or night, you don't need to locate the lock hole to conveniently unlock or lock the car from a distance. 2. Principle of remote keys: The key emits a weak radio wave, which is received by the car's antenna. The electronic control unit (ECU) identifies the signal code, and then the system's actuator (motor or electromagnetic coil) executes the action of unlocking or locking. The system mainly consists of two parts: the transmitter and the receiver.
