So this afternoon I got a "Low battery key fob" warning. First car I can recall giving me that warning. Most of the time it just won't unlock doors or start with you anymore. However, I can't quite figure out how to replace the battery. I took the physical key out of the fob, so now does it just pull apart to get to the battery? Afraid to just pry open for fear of breaking a tab or something. Any advice?

Well you are the first why did you not video and share.
Guess I am the one going to do a video exchange on how do I open a fob and show.
Your key fob contains all the tools needed to replace the battery:

2017 CRV EX-L with Nav Turbo. Real world key fob battery life: 2 years & 2 months. I have used the Fob to remotely start/lock the CRV almost exclusively several times a day so, more conservative use should get even longer battery life.
The CRV will show on the car display when the Key battery gets low with a message you can't miss or misinterpret. I did not have to reprogram the Fob or manually reset the low key battery message after putting in a new Key battery but it did take 2 starts for the message to go away.
(This is not the OEM Honda Key Fob battery but a lithium Energizer CR 2032 3-volts replacement I bought at Walmart. 6 for less than $6 with tax. 10 year shelf life. I replaced the original crazy acting Fob battery for a reason that turned out to be an OEM car battery issue which caused the Key Fob to act up.)
**Simple to open Fob & replace battery but my big issue was getting the two halves to snap back together properly; one side always seemed not to snap down fully. Just had to work at it. Couple of good how-to videos on the internet about how to do this & one for what to do if the buttons, etc fall out. Work on a flat surface such as a table to prevent all of the buttons from falling out. (I still have not found instructions in the owner's manual for how to replace the Key battery.)
--Remove metal key from Fob & use the metal key to pry the two parts of the Fob apart.
--Coin battery is held down by 4 plastic tabs. Use a small screwdriver to gently pry out the battery. (I was using a larger screwdriver from my key chain but saw it lifting the whole face with the buttons up & went for smaller screwdriver to slip under battery.)
--Put new battery under 2 tabs & press down to lock it in place under all 4 tabs. Don't forget to peel sticky plastic protector off the new battery.
--Put battery half on flat surface. Align the 2 halves of the Fob together & press down to snap in place. Check entire Fob perimeter to be sure there are no gaps.
--Put the metal key back in.
--TEST the key fob functions!! Don't wait until you need it to find it does not work.

What i do is I leave a spare battery in the car. if they smell like vinegar . then you can get some salad, no toss to the trash correctly recycle the bat. if they made these rechargable and usb typed imagine the fun that be?
I have only owned my CR-V for a few months but I also have a 2014 Accord. I have used the Accord for food delivery for almost the entire 3 years I have owned it. I lock and unlock the doors probably 30-50 times a day and have yet to replace the battery in the fob.
I buy the batteries in bulk on Amazon... for a range of different devices I need them for. It is a very common battery size, and I pay ~$0.50 per unit buying them in blocks of 20 or 40... and these are top tier name brand Sony batteries and they have always had long shelf life remaining when purchased and have long service life in the family fitness trackers.. which is my standard for battery life metric in our home.
Note: My 2017 is over 3 years old now and still on it's original batteries in the fobs. Then again.. I NEVER use the fob to lock/unlock, or remote start, or any other feature that uses the high power transmitting mode of the fob.. so mine is in low power passive mode all the time.
