My Fob and Mobile Key stopped working about a month ago. I called 2 weeks before I left for vacation - the 800# person told me the local service center would be in touch. It took 3 weeks for a response. New Tech showed up last week and couldn't figure out the issue. He said today he's bringing an experienced tech out that has experience with this issue. For me, it's a proximity issue - neither fob nor mobile key is recognized by the car after numerous deleting them from my profile, adding them back, etc.
This happened about 9 months ago and the Tech that came out did get it going by disconnecting/reconnecting something in the trunk. After that, it started working again. Because others are having similar issues now, it may be something related to software...
