So just got a low battery notice in my 2017 for the key fob. I followed the video someone posted here on how to open the fob but now I am wondering if this battery can be just bought at any store like Canadian Tire? and once I install it am I good to go or do I have to reprogram the fob, the car or sync them at all? Also if the battery fails totally I guess I can use the key to get into the car but will it start?

The US 2017 CR-V Owners Manual has a page that shows how to replace the batteries in both the Master Key with Remote Transmitter and the and the Smart Entry Remote. It lists what type of battery each takes, and from the battery numbers I know they are available at most places that sell the "coin" style round batteries.

They instructions are titled "Remote Transmitter Care". What does your Owners Manual say?

you can buy the CR2032 battery literally at any local drug store, hardware store, department store, or online.

All you have to do is follow the instructions in the owners manual to change the battery, or follow the video you referenced.

NO reprogramming is required of the FOB after a battery change... as long as you don't beak it.

Note: the most common issue owners have is allowing one or more of the buttons to get misaligned during the change process... which is why they tell you to lay the fob down flat on a surface before "gently" removing the battery and replacing it.

Thanks, I bought the battery today, pried the fob apart, installed it and put back together carefully and it works just fine!

I have had my CRV for 2 yrs 6 mths. the FOB battery warning popped up today.
Just curious how long before others got the warning...
I know these new FOB continually work off the signal..... and my 2001 Accord key battery lasted 12 yrs.

My "Low Battery" warning just came on tonight (have not been driving very often under COVID). The car was made, as I recall, in Feb. 2018 and it is now Sept. 2020, about 2.5 years. Although I was surprised by that seemingly short time period, the owner's manual says to expect about 2 years:
Communication between the smart entry remote and
the vehicle consumes the smart entry remote鈥檚
battery.
Battery life is about two years, but this varies
depending on regularity of use.
The battery is consumed whenever the smart entry
remote is receiving strong radio waves. Avoid placing
it near electrical appliances such as televisions and
personal computers.
I originally left the remote in the car for several days, until I read (somewhere) that doing so can shorten the battery life because the car will constantly be talking to it (sounds like my wife...). I am careful now to keep it away form such things (yes, my wife, too) -- but it is a pain to go into the garage to grab something and not have it with me....

Thanks to all here. I could not find it in the manual, because I don't call it a "Remote Transmitter." It's a KEY, dadburn it!

Welcome to the forum, R.F.M!

I can't tell you how many times I have walked in your steps, to the garage with my FOB (this what I call it), Both my and my wife's car have FOBs. I USUALLY have my FOB in my pocket, but almost never have my wifes, yet somehow, it seems I more often am after something from her car. After owning Hondas with this tech for about three years now, I have finally trained myself to grab her FOB before going out to the garage.
