I don’t seem to find in your posts the year, model, and current miles on your Insight. This is basic information one would need to help you.
Thanks for putting your location in your profile, that kinda helps too.
Do register your Honda at:
With your VIN number and it will tell you if there are any open recalls, allow you to store your radio code, tell you exactly what model it is, and give you access to owner’s manuals.
The locking/unlocking behavior is controlled by settings in the MID (multi information display) How to do that is in the manual.
The CVT fluid is OK if anywhere between the two marks.
What did the dealer have to say about it on their inspection report?
