Most key codes are blind codes, and publication of code books or software is restricted to licensed locksmiths in most jurisdictions for security reasons.

VW and other European manufacturers are requiring that the key transmits the unique VIN of the vehicle. To increase security, some OEMs are requiring the key to transmit more than just the ID code. Chrysler, VW and other makes require PIN codes depending on specific model years. But, some key programming tools can harvest the PIN code from the modules. You can contact the OEM for the code or in some cases it might be found in the owners manual in the glove box if you are lucky. This code resides in the module for the immobilizer system. One of the changes made to some late-model vehicles is the requirement to have a three- or four-digit PIN code to perform onboard programming. The vehicle gets the key’s transponder to transmit, and the unique ID is learned by the vehicle during the procedure. Onboard procedures use the antenna coil on the vehicle to read the transponder or ID number in the new key or remote. You might already do this at your shop if you have the right scan tool and software. Newer vehicles require a scan tool to learn a new key or remote to perform onboard programming.
