My independent mechanic did the service, but his analyzer isn't finding the proper location to reset the service warning. I've found/seen several videos on YouTube, but several of them are contradicting each other and none of them seem to start off with the car shut down. I tried several videos repeatedly and can't do it correctly.
Any help greatly appreciated.

Well I googled it, but holy chips in dip there are so many strange answers out there (e.g. you have to remove the keyless go button, which is false)
