How to Duplicate a Car Key Without the Original Key?

[DeJayla]

To duplicate a car key without the original key, you can take your vehicle documents and personal ID to a 4S shop or a repair station. In this case, you need to provide the 17-digit anti-theft code and the key tooth shape number. Alternatively, you can directly replace the entire car lock. Additional Information: 1. Spare Key: Usually, cars come with two keys, one for regular use and the other as a spare. When the regular key is lost, the spare key can be used to open the car door normally. 2. Anti-theft Code: Each car has a built-in anti-theft code. The reading coil of the car ignition lock cylinder can read the chip of the key to obtain the fixed anti-theft code. At the same time, it erases the original key information read, making the lost key an illegal key.
