Can Car Remote Keys Be Duplicated?

Car remote keys can be duplicated. The 4S shop needs to query the anti-theft password for configuring the key through the database based on the vehicle license and the owner's ID card provided by the owner, and then configure a new metal key according to the key tooth shape number. The functions of the car remote key: 1. Remotely lock and unlock car doors; 2. Press and hold the lock button on the remote key after turning off the engine to close the windows; 3. Press the red horn-shaped button on the car key to locate the vehicle or send a distress signal; 4. Press and hold the trunk unlock button to automatically open the trunk; 5. Press the unlock button on the remote key once to open only the driver's door, press twice to open all doors.
Of course, car remote keys can be duplicated! I once lost my keys and got it sorted at the 4S shop directly. They scanned my car's VIN with a computer and made a new key for me—the whole process took about half an hour. However, you need to bring the car along with the owner's ID, or they won’t proceed. The complexity of key duplication varies by car model—older cars are simpler, while newer ones cost more, usually around 200-300 RMB. It’s a good idea to keep a spare key at home just in case. Duplicating a key can also fix issues like unresponsive buttons on old keys—after I got a new one, the remote range even improved. In short, it’s no big deal, so don’t worry.
I tried pairing a car remote key myself, which was quite fun. You can buy a pairing tool online for a few dozen to over a hundred yuan, connect it to the car's OBD port, and then follow the steps in an app. Just make sure not to get the model wrong when doing it yourself—some cars require entering a specific code, otherwise the pairing will fail and all your effort will be wasted. This method saves money, especially for ordinary car models, but inexperienced people should watch video tutorials first to practice. The key is to replace the old key in time to avoid poor contact due to wear. Overall, DIY isn't difficult, just a bit time-consuming.
