If your VW has an immobilizer, you will need to program it before it will work. There are a few different ways to program an immobilizer, and the specific steps will vary depending on the model of your VW. Here are the general steps to follow to program an immobilizer:
1. Locate the Immobilizer Control Unit (ICU) on your VW. This is usually located in the dash or near the steering column.
2. insert your key into the ignition and turn it to the On position.
3. Press and hold the Lock and Unlock buttons on your remote control at the same time for approximately five seconds.
4. Press and release the Lock button on your remote control. The doors of your VW should lock and then unlock to indicate that the immobilizer has been programmed.
