Can car remote keys be duplicated?

[Ingrid]

Car remote keys can be duplicated. Each remote key has a unique code that is also stored in the vehicle's anti-theft system. To duplicate a new remote key, it needs to be matched with the code in the original vehicle. It is recommended that car owners go to an authorized 4S store for duplication to ensure vehicle safety. Remote keys are used to open and close doors as well as start the engine. The working principle is: the remote key emits radio waves, and after the car antenna receives the waves, it controls the car to perform a series of actions. Nowadays, remote keys and mechanical keys are used together, with remote keys handling door opening and closing, and engine starting also controlled by the remote key.
