How to program an incorrect Volkswagen key 01179?

Remove the cover of the driver's side door handle (some models like the new Jetta do not have a door handle cover, so no need to remove it). After pressing the unlock button on the car key once, stand next to the car and within 1 minute, use the spare key or key head to insert into the lock cylinder to unlock the car. Turn on the ignition with the car key, and the synchronization process is now complete. Reinsert the spare key back into the car key or fold the key head, and reinstall the door handle cover. The remote transmitter and battery are both installed inside the remote key.
I've repaired many Volkswagen vehicles encountering the 01179 key error issue, which is actually the immobilizer system failing to recognize the key. You need to use professional equipment like ODIS or VCDS, plug into the OBD port, and access the immobilizer control unit. First, check the password—it's on the key tag or that small slip of paper in the vehicle manual. Entering it wrong three times will lock the system, making it even more troublesome. When matching a new key, you must have all existing keys placed inside the car; missing even one won't work. Last time when handling this for a client, it failed twice in a row—later, we found out the car wasn't completely turned off. You must switch it to the OFF position and wait until the dashboard is completely dark before proceeding. The whole process is most vulnerable to power loss, so it's best to connect a voltage stabilizer for stability.
