Part: Key

To perform this operation, a specific tool is necessary that allows you to code your key without issues. Once you have equipped yourself with the required tool, connect it to the OBD port to interact with your vehicle's onboard computer. Now, simply turn on the tool and connect it to the vehicle following the steps described in the video. As you will notice, it will be necessary to let the panel run for a while before the operations can be completed, so when prompted, insert the key to program it, and you're done!
