Did a search and couldn't find any threads specifically for the Gravity key fob problems.
We've (wife and I) have been having key fob problems whereby sometimes the key fob would take a long time to work both for unlock and lock and sometimes would not work at all. Seeing that the key fob has downloaded software I decided to give the "remove battery" method a try, I opened the case (use a small blade screwdriver) and popped the battery out and left the battery out for about 15 to 30 seconds. Since the removal of the battery and reinsertion the key fob's have been working great, I'm a very happy key fob user at least currently. I did not replace the battery, only removed and reinserted the same battery. I've not tried using the buttons on the key fob since removing and reinstalling the battery
I'm of the opinion that removing the battery does a hard reset of the hardware and software on the key fob and gets key fob back to a known good state. How long this will last probably varies depending on how one uses the key fob (pressing the buttons, ...).
I'll note that I've never had a problem with the NFC card
I'll also note that my wife and I both have profiles on the Gravity and each of us has our profile assigned to the key fob and NFC card we each have.
I've setup a poll question on how your key fob works (hopefully the poll works)
