I had in my pocket a brand new key that was just purchased a week ago, so it can't need replacing yet!
The message does not go away if I change keys.
I'm thinking it's some sort of bug.

New fob, or new battery? If you just bought a new fob, it's possible the fob was sitting somewhere for a while, with the battery slowly draining.

I wouldn't be surprised if that "new" battery you bought from them has been sitting around for a while too.
If 2 fobs are doing it it is probably not the fob. First try a reboot. If that does not work take it into the SC.
I had that message on my screen for a month. I had taken it into the service center a week after this message started happening. Brought both fobs with me. They replaced the fob batteries and said the message should go away soon. It didn't. I replaced both batteries on my own twice and still had the message. A mobile service tech came to take care of a different issue on the car and I explained the situation to him about the fobs and he replaced both of them on the spot for me under warranty. He said if I had gone through that whole process that many times then most likely one of the fobs was malfunctioning and it would be best to replace.

Previously when I replaced the battery in my key, the message went off, but today, I had to replace the battery in both my keys to get rid of the message. The difference this time was that my wife used my 2nd key while the message was ON. Therefore I believe it works like this:
The message goes ON when the car sees a key with a low battery and goes OFF when it sees that SAME KEY with a new battery.
However, if the message is ON and the car sees the 2nd key with a low battery, the message goes DOUBLE-ON so it needs to see both keys with new batteries before it goes OFF.
Both my batteries measured 2.99 volts, so it seems like a battery is low if it is under 3 volts (new batteries are 3.3 volts).
BTW - a pack of 20 Sony batteries are only $7.50 on Amazon.

In my case, my replacement batteries, while new and reading over 3 V where knockoff batteries. I then purchased brand-name and the problem went away.
I have 3 fobs, so I guess I'll have to change all three and see.
What type of battery is this? I'll get on Amazon and by a pack

Right, for a Model X it is a 2354. I have the same problem and haven't been able to find the battery anywhere.
I bought a pack of 5 off of eBay for $3 shipped. The service center put a new one in the key fob they had and gave me a battery for the other one.

I just bought 2 of the CR2354s at BatteriesPlus. There were too many bad reviews of various CR2354s on Amazon that I felt like I didn't want to trust any of them. I'd have preferred cheaper batteries, but $11/year for 2 new fob batteries isn't something I'll worry about.
