Hello,
An indicator on my dashboard told me that my key fob battery was low. I purchased the 2017 Civic Sedan Touring new in December 2016. That would make the battery a little over two years old.

The battery in my CRV fob was still going strong after seven years.

What should be the life expectancy of the battery? I went to the dealer and it only cost five bucks and took five minutes for them to replace the battery – that was nice.

I have a feeling I'm pocket-pressing the buttons. Once, first thing in the morning, the rear passenger window was down. Once the trunk was open. I've seen the lights flash for no apparent reason.

I keep the keys in my pocket. Has anyone found a tightly fitting case? All the ones I have seen seem to be much too big – they are probably 5 times larger than the fob. A hard shell case that tightly fits the fob and protects the buttons from being accidentally pressed would be perfect.

Barry.

FWIW (of course I can't find the thread now) - a good number of people said they had to replace their key fob battery after about 2 years, including me.

Mine was almost exactly 2 years. It's a $2 battery, so NBD.

Up until a few years ago, I can't remember ever having to change the battery in a fob, and a few of the cars I had for 5-6 years. Now, everything I've had since about 2014-15 have all needed new batteries at right around the two year mark.

Thanks for all replies. I found one on Amazon that seems to work – I just got it today.

It looks good. I don't use the belt hook and I used scissors to cut off the flaps at the bottom. It fits snugly around the key fob and hopefully will protect a little against accidental pocket-presses. The case can be easily removed if I need to get the key or press the buttons.

My key fob battery lasted about two years – I guess this is the new normal. My dealer replaced the battery in less than five minutes for five bucks. Unless I go online that is almost cheaper than I could buy a battery and replace it myself.

I found this on page 138 of the Owners Manual.

Communication between the smart entry remote and
the vehicle consumes the smart entry remote’s
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.

If you do try to replace the batteries, be careful of the actual buttons falling out of the shell. I did this in the dark dimly lit cabin of the car and lost 3 of the 5 button. I still have the electronics guts, so swapping it into a replacement fob when it comes in.https://www.carandtruckremotes.com/honda-remotes-civic-remotes.html

3 years and changed twice. But I use it a lot. At least 20 to 30 press each day. but why ask the dealer? $5 can buy some high quality pack of 4.
