Where can I get a car key duplicated?

[AdalynnLee]

You can directly go to a car 4S store to duplicate a car key, or you can also go to an auto parts market to duplicate a car key. Here is some relevant information: Car key functions: In addition to controlling the opening and closing of car doors, car keys can also control the opening and closing of windows and the trunk. These two functions are also commonly used in daily life. When you want to increase air circulation inside the car for ventilation or to remove odors, you can conveniently use the remote control to roll down the windows. Working principle: When the car owner presses the button on the key, the key sends a signal containing corresponding command information. The car's antenna receives the radio wave signal, and after authentication by the Body Control Module (BCM), the actuator performs the unlocking/locking action.
