What is the method for matching keys for the old Santana?

[BrielleLynn]

The chip in the Passat is located inside the key. If you replace the ignition lock, you only need to take out the "chip" and place it into the new key. Below is the relevant information: Additional Information: The remote key not only has a remote function but also a primary function, which is anti-theft. After the matching is completed, the new remote key can be activated, and the lost key will immediately become invalid. Even if someone finds the lost key, they can only open the car door mechanically but cannot start the vehicle. Remote Key: A remote key utilizes the wireless remote function of the central locking system, allowing you to unlock and lock the doors from a distance without inserting the key into the lock. It achieves the basic function of opening and closing the car doors.
