Volkswagen Radio Code
In factory car radios and navigations, Volkswagen uses the anti-theft protection of the vehicle by encrypting it with a 4-digit PIN code. In theory, disconnection of the power supply should not cause the need to re-enter the code. In practice, radio or navigation can sometimes display SAFE or CODE message. This is connected with the need to enter the factory PIN code. Entering the code will always be unavoidable during the replacement of radio or navigation (e.g. to a newer model).
The radio or navigation code should be inscribed in the vehicle’s book or on a special card – Radio Code. The code is assigned to a 14-digit serial number of the device (VWZ***). Some older VW models of radios (such as Alpha, Beta or Gamma) can be decoded with the use of decoders (code calculators) for free. Newer models are encoded with the use of “strong” algorithms, and unlocking requires the use of special software and an interface. Services related to the remote unlocking of the car (ON-LINE) are provided by specialized online providers. You can also get help in authorized VW services.
