It doesn't fix the problem, but it resets the clock until they fall off again. In Texas, it was <48 hours between dropping my Macbook off at the Apple shop and receiving it on my doorstep.
I just followed your link, and had an interesting experience. Of all of the Apple Stores and Authorized Repair they do not appear to be accepting repairs. Everyone of them tell me:
"This location has no available reservations.
You can check another location now, or check this location again tomorrow."
Can't even get far enough to see if the repair would be covered. Good job Apple
48 hours is pretty optimistic. At least for the 2016 model they can't just change the keycaps but they'll have to change the whole bottom case. This took a few weeks for me since I had to send it to a certified repair center.
That's the same for the 2017 model that I had to fix. I got a new mobo + battery. Convenient because my battery was in dire need to servicing.
I heard it would take weeks and even had a backup laptop ready, so it surprised me when it came <2 days later. It was my original laptop too (had all my data and the same dent).
Oh well, the new models don't have this issue anymore. What a fuck up.
The big question is will they extend the warranty by the number of months the Apple Stores were closed due to pandemic lock down? My keycaps didn't start misbehaving until about April.
If you still have time, get your keyboard replaced for free: https://support.apple.com/keyboard-service-program-for-mac-n... (it also means they have to replace your mobo and battery due to brilliant Apple engineering).
