OBD2 programming is a popular choice due to its direct access to the vehicle’s electronic systems. It generally offers a more robust and versatile programming capability compared to onboard methods. However, it does require a compatible key programmer OBD2 tool and appropriate software. It’s also important to note that not all vehicles support key programming via the OBD2 port for security reasons.
“On-Bench” or EEPROM Programming: This more advanced technique, often referred to as “on-bench programming” or EEPROM (Electrically Erasable Programmable Read-Only Memory) programming, involves a more hands-on approach. It requires physically removing the vehicle’s electronic control module (ECM) or immobilizer unit from the car and programming the key using specialized equipment on a workbench.
The ECM or immobilizer unit contains an EEPROM chip that stores crucial key-related data. On-bench programming directly targets this chip to program keys. This method is often employed for older vehicles or those with complex security systems where OBD2 programming might be limited or impossible. While more time-consuming and requiring specialized skills, on-bench programming is a valuable technique for professional locksmiths and automotive technicians for intricate key programming tasks.

VIN and Key Programming: What You Need to Know
It’s a common question: “Can I program a key with just the VIN?” The answer is generally no. While your Vehicle Identification Number (VIN) contains crucial information about your car, including its make, model, and year of manufacture, it does not contain the specific cryptographic key programming data required to add or reprogram keys.
Key programming is a security-sensitive process that typically necessitates direct access to the vehicle’s onboard computer system or immobilizer unit. This access is needed to input unique codes or data associated with the new key. This process usually requires either a working existing key for the vehicle or a key programmer OBD2 connected to the vehicle’s OBD2 port for secure communication and programming. Resources like “Where to Connect OBD2 Scanner” can guide you to the OBD2 port location in your vehicle.
While some locksmiths or automotive specialists might be able to generate key codes based on the VIN for certain vehicle models, this is not a universally applicable method and may not be possible for all makes and models due to security measures. Even if key codes can be generated from the VIN, access to the vehicle itself is still typically required for the actual programming process.
In summary, while the VIN is essential for vehicle identification and part look-up, key programmer OBD2 tools and direct vehicle access are usually necessary for successful key programming.
