Thanks for the video, I have the same issue with driver door ajar and the same smart lock/alarm etc.. Do you happen to recall the part number for the Door Latch Assembly you purchased?
the cable to my door latch snapped and I am attempting to repair it versus replacing it, it snapped right where the cable meets the end part that goes into the hole
Could you tell us why you had to replace it in the first place, just out of curiosity? My door ajar light keeps flickering on and off while driving and I'm wondering if this replacement would fix the issue...
