The car pass contains important information to enable programming to be carried out on your vehicle. The most important details are the Security Code and the Mechanical Key Number.
It is not possible to carry out much programming or retrofits without this information.
Here at tech2.guru we have developed a method to extract the security code from the vehicle directly. So unlike others we never turn a customer away for not having their security code.
We can request the Security Code with just the VIN if you provide proof of ownership of the vehicle.
