It can't be the timing. I watched a video of a guy where it works for him, and I followed his timing. The only thing in his timing that was slightly different from mine to begin with was the ending where you turn the key on and then off. After adjusting to the way he did it, which was a slightly longer pause, there was no change. I tried it all.

I tried all of the above 100 times or more, and it never does the final step where the door locks and then unlocks.
