I was able to complete it myself and it was not overly complicated. The website did not properly load up directions for myself on my phone. Only after playing around for a while was able to get the instructions there were dead links on the actual website. The instructions were followed to the letter and repeated when it did not work after the installing the extension kit and pairing the fobs and getting confirmation blanks. My vehicle would not crank over in my engine through a half dozen codes, my dashboard lit up as well. After disconnecting the unit, it still did not start the engine. Long story short. I followed the original instructions after connecting the rf edition and now everything works, including the new fobs and current key click link in description for more reviews.
