I was on the road for three weeks. My MS90D was garaged and plugged in the entire time.
When I got home, I tried to open the car to do a system update. Neither keyfob worked. One is my daily driver (and sits out of range). The other is my backup and sits in a lock box. I was able to open the car with my mobile phone and did the update. I tried both keyfobs again... nothing. I tried all the fixes that I could think of... changed the battery in each keyfob, rebooted the car, etc. As a final test, I tried putting the keyfobs in the positions that the manual says will work if the battery is dead. Nothing. I called roadside assistance and was told it had to go into service.
I made an appointment on the mobile app. A ranger was scheduled to come to my house... (wait for it) in 3 WEEKS!
Following the suggestion of the non-trolls (people who don't use terms like RTFM) of several people in the forum, I showed up at the service center this morning. The check-in staffer did everything I did to no avail. The car was handed off to a tech. Two hours later both of my keyfobs were working. The car had to be reprogrammed to recognize them. No complaint about the service in general. They did open the units to check for "water damage" which was one of the reasons it took so long. I guess they have had people try to scam them for the new 80-bit keyfobs or something.
The tech said this was a first for him. He had no explanation. It was just 'one of those things'.
