The other evening my wife mentioned that she thought the fob for her 2016 Hyundai Tucson needed a new battery since the driver’s door wasn’t as responsive any more. I had some CR2032 batteries handy and went ahead and replaced hers. In the process, it occurred to me that I’ve owned my 2009 Corolla f…

I have never replaced a battery in the key for my 1991 Honda CRX. :wink:

The batteries last longer in older cars. I got about 3 years from the battery in my 2015 Accord EX-L key fob. It doesn’t seem long compared to my 1998 Buick Regal, with battery replacement at about 8 years. They serve different functions though. The Accord fob does everything the Buick fob does, but…

I will probably replace the batteries in our 2017 fobs in the net year. Some cars give you a low battery fob warning.

Before I started my practice of leasing a new car for my wife, she had a 2008 Chrysler Pacifica that we bought new. When we traded it in August 2016, the key fob battery had never been changed.

I haven’t paid much attention. I think my secondary key for my 16 yo truck still has the original battery. But I never use it. The primary has has 2 or 3 batteries and a replacement case and button covers. I changed batteries a few times on our old Saab in 15 years in each key.

2000 Dodge Stratus my wife bought new april 2000 with 2 fob’s baterry’s still going strong in june 2015 when it got totaled.

I don’t really keep track and I’m not interested in seeing how long they will go, but I think it was 3 years on the Acura when I got the message to replace the battery. Now on the remotes for the garage door openers I’m a little more concerned and replace them all about every year. I have one on t…

Original batteries in both fobs for my 2003 Camry still working when sold a month ago…

I’m at 6yrs for the fob battery for my 2015 Forester, I’ll buy a new battery just to have since it’s simple to change

It might be more of a range issue than just not working. I know with a good battery I can hit the auto start from half way across a parking lot but not with an older one.

The fob for my 96 Lincoln still has the original battery and it still works for some strange reason. I would have thought it would have needed to be buried a long time ago.
